How many watts are typically needed for basketball court lighting?

Nearly 400 mu of farmland in Ang'ezi Village, Harajun Township, has long suffered from water shortages. Due to the village's weak economic foundation, this problem had not been solved. The working group raised 15,000 yuan from multiple sources to purchase water pipes, and the village committee organized farmers and herders to dig trenches and bury the pipes. After two days of intense labor, irrigation water was successfully delivered to the main canal 200 meters away.

The working group of Atush City Commerce and Information Committee and Audit Bureau stationed in Tashpushka Village, Shangatush Town, learned that college student Rouzaji Mohedar had to suspend his studies due to family poverty. After communicating with the boss who was building a cultural activity room for the village committee, they arranged for Rouzaji Mohedar to work at the Aketao construction site, with room and board included and a monthly salary of 4,500 yuan. They also paired him with a long-term support partner.

The most basic of these units is the candela for luminous intensity. Like many other physics units, it has a mouthful and brain-burning definition: under a standard atmospheric pressure of 101,325 newtons per square meter, the luminous intensity of an absolute "black body" (an ideal object that absorbs all external light without any reflection) with an area equal to 1/60 square centimeter, at the solidification temperature of pure platinum (Pt) (about 2042K or 1769°C), along the vertical direction, is 1 candela.

People who do not understand teachers think that teachers have a comfortable and regular life, working nine to five, with long winter and summer vacations, and performance pay based on more work, more pay.

 Long-term cooperative training can be provided for badminton, table tennis, basketball, football, tennis, taekwondo, tai chi, square dancing, balance bikes, roller skating, fun sports games, and other indoor sports.

Due to recent heavy rains, many places on the campus roads have become muddy, and some cleaning of the asphalt roads has been carried out. In the dormitory public areas, we have assigned professional departments to monitor the preparation of disinfectant and the spraying of public areas to respond to the epidemic. In response to students' feedback, to reduce mosquitoes on the first floor of the teaching building, mosquito eradication actions have been carried out for four consecutive weekends.

Recently, the working group of Shanghu Town, Korla City, has helped the village (community) improve cadre style, enhance villagers' skills, improve infrastructure, and strengthen the collective economy through strengthening team building, quality improvement, position construction, and demonstration leading.

Not afraid of the scorching heat, they dug and cleared water channels under the blazing sun, carried out watering and irrigation work for the forest belts, and ensured that the trees in the shelterbelt had sufficient "drinking water."

A: Maintenance work pursues timeliness. Sometimes maintenance work not only involves construction in the dormitory that needs repair, but also requires certain repairs in the dormitories above and below it. On the public account, you can choose whether to allow workers to enter the dormitory when no one is there.

Control personnel entry and exit, disinfect and ventilate the teaching building and dormitories. Corresponding facilities have been arranged at the dormitory entrances, and dormitory managers are responsible for checking students' temperatures.

Teachers are sacred educators, but teachers are also ordinary people. Teachers should also have the right to be themselves. To make teachers change their minds, we need to change our attitude first.

Recently, the working group of the Party School of Changji Prefecture stationed in Baojiadian Village organized night school study. The working group members studied the spirit of the relevant documents on "Three Stricts and Three Honests" education and watched the educational film "Family Planning Policy."

How high is the standard pole for basketball court lighting?

It may be difficult for ordinary people to understand: compared with a teaching career of thirty-one years, wouldn't seven years pass in the blink of an eye? Why insist on resigning just before retirement? Isn't this unnecessary?

If someone asks you, "How bright is that street lamp?" or "How bright is this high-intensity flashlight?", most people probably don't know how to answer. Light bulbs at home usually indicate how many watts they are, but watt is not a unit of brightness; it is a unit of power. A 50-watt incandescent lamp is not brighter than a 10-watt Sixth Workshop LED flashlight. So using wattage to indicate brightness is unreliable.

Third point: avoid hitting to the midcourt. As long as you are an experienced player, after returning a shot, you will have a recovery movement, subconsciously returning to the midcourt. If you always hit to the midcourt, you are giving your opponent more chances to attack. Hit more to the sidelines, especially to your opponent's backhand area; he will be very passive!

Parents were dissatisfied and wanted to complain about the teacher to the relevant departments. The teacher, forced by helplessness, had to resign from the position of head teacher and let a more suitable person take over.

Another teacher's handwritten "leave request" was actually a resignation letter. He wanted to resign from the position of head teacher only because he accidentally uploaded student grades to the parent group.

Recently, Kuleudu Mailisi Village held the first report (democratic evaluation) meeting of the village two committees (village cadres). The evaluation work was jointly organized and implemented by the town party committee and the working group. From designing evaluation forms, innovating evaluation methods, to emphasizing the application of results, every link reflects the original intention of changing awareness and establishing concepts. (Working Group of the Autonomous Region Department of Transportation)

Fifth point: use backhand less often. You are not Taufik, so you cannot play Taufik's backhand. My view is that when you can use a forehand shot, do not use a backhand shot. After all, the power and accuracy of the backhand are far lower than the forehand, especially when playing to the backcourt. Often, a backhand shot only reaches the midcourt or mid-backcourt, which is exactly the best position for your opponent to smash. If you really have to use a backhand, use a drop shot to the net. The power is easier to control, and it can turn you from passive to active!

On August 1, the "Fang Hui Ju" working group of Asuke Community organized all members to study the spirit of Secretary Dou Wangui's speech at the regional "Fang Hui Ju" activity promotion meeting. At the meeting, the achievements and highlights of the first half of the regional "Fang Hui Ju" activity were conveyed and interpreted, as well as the focus, main direction, and work goals for the next stage.

A: The basketball court lights are on until 9:30, and the playground lights are on until 10:30. It has already been mentioned that the stadium lights are open from 7:00 to 10:30.

First, the resignation of teachers reflects that teaching is not an easy profession, and the teaching path is not relaxed. Pressure from all sides has deprived teachers of much freedom.

Starting from July 15, with the support and help of Tarim River Seed Industry of the First Division in Alar City, the working group donated and installed 6 brand-new solar street lights in the village, building a lighted basketball court. These solar street lights automatically turn on and off according to the intensity of light, and light up automatically once night falls, becoming a beautiful scenic line in the village. They not only improve the village appearance, but also greatly facilitate the activities of the villagers, and safety is better guaranteed! (Huang Zhuo, Working Group of the Youth League Committee of Xinjiang Production and Construction Corps and the First Division)

Fourth point: cross straight and diagonal shots. Saying that you should avoid straight shots is wrong, because your forehand straight shot is exactly your opponent's backhand area, so hitting straight is very effective. But if you always hit straight, your opponent will figure out your shot pattern and easily resolve it. So you should occasionally play a few diagonal shots. But it is also incorrect to always play diagonal shots, because diagonal shots have a longer flight path, which is also your opponent's forehand area and is easy to intercept. In addition, diagonal shots have a higher out-of-bounds rate. The correct approach is to cross straight and diagonal shots!

A 160W LED floodlight saves 31,864.5 - 11,169 = 20,677.5 yuan per year compared to a 400W metal halide lamp, saving 65% electricity.

When using a flashlight, we all have experience: if the light spot is focused very small, it looks very bright. If the light spot is enlarged, it is not as bright. This involves another concept related to brightness: illuminance, whose unit is lux. The definition of lux is the luminous flux per unit area. If the luminous flux on an area of 1 square meter is 1 lumen, the illuminance is 1 lux.

Completed 2012 orders. More than 400 floor tiles were repaired before May 3. This month, the swimming pool sports system will be renovated, and electronic clocks will be installed in the teaching building. The septic tank and wiring system of the teaching building have also been regularly maintained, and 4 emergency incidents such as sudden water pipe bursts at night were resolved last month.

In Tijian Village, Gedaliang Township, 24 households have long had difficulty using water. People and livestock had to fetch water from 4 kilometers away. The working group raised 12,000 yuan to purchase water pipes, mobilized the masses to contribute labor, and after four days of work, successfully delivered tap water to every household.

Currently, the school basketball court has insufficient lighting. At night, when teachers and students exercise on the playground, they cannot see the ball path clearly because of insufficient lighting, which often leads to injuries when receiving the ball due to excessive ball speed. What we can do, and what can avoid such incidents as much as possible, is to improve the lighting situation of the court.

To understand this, you can analogize to pressure units: the same force of 10 newtons pressed on your hand through a ceramic tile will not cause much feeling. But if the same force is applied through a needle, it will deeply pierce into the flesh. Similarly, a 100-lumen flashlight used to illuminate the entire basketball court can only barely allow you to see the words in a book. But if concentrated into a laser beam, it will be as bright as a Jedi knight's lightsaber!

As night falls, the lights on the basketball court of the Bostan Village Committee in Keping County come on. Villagers happily play volleyball, children ride bicycles and play joyfully, and women sit on blankets chatting about daily life...

It can be seen from the words that the two teachers who voluntarily resigned are definitely not the type who are irresponsible to students. On the contrary, they respect their teaching positions, but forced by cruel reality and pressure, they had to resign.

But it is not a good thing for teachers to resign one after another, especially for primary and secondary schools. The loss of excellent teachers is the greatest educational loss, and public schools are in an even more difficult situation.

160W LED floodlight: 0.17 kWh/unit × 5 hours × 365 days × 1.0 yuan × 36 units = 11,169.0 yuan;

Actually, this teacher just wanted to keep these seven years for himself, to live for himself once again, and was unwilling to be controlled by others for his whole life.

Common units related to brightness in physics include the candela for luminous intensity, the lumen for luminous flux, and the lux for illuminance.

First point: don't make your shot patterns too monotonous. Smash, clear, drop, drive—these are basic shots, but you can vary the patterns: smash straight, smash diagonally, slice smash, point kill, change high clears to flat clears, pull to the backcourt straight, pull to the backcourt diagonally, drop shots can be diagonal, reverse slice drop shots, drives can be straight or diagonal. Besides the main patterns, practice more return of smashes, flat block drives, net shots, pounces, lifts, plus occasional feints. The richer your shot patterns, the more difficult it is for your opponent. To play badminton well and beat your opponent, your shot patterns must be rich!

Because LED has huge advantages compared with light sources such as incandescent lamps, fluorescent lamps, and gas discharge lamps, it will replace them in 10 to 20 years and dominate the entire lighting industry. Various countries have invested a lot of human and financial resources to start semiconductor lighting plans, as shown in the table.

In fact, sometimes playing badminton doesn't require many skills. If you thoroughly understand these five points, you can beat half of your opponents. I hope this is helpful to all readers who play badminton!

1000W metal halide lamp: 0.485 kWh/unit × 5 hours × 365 days × 1.0 × 36 units = 31,864.5 yuan;

Faced with these questions, most people can answer calmly: I am 1.75 meters tall, this bundle of cabbage weighs six and a half jin, this device uses a 12V power supply, and that radio station's transmitting frequency is 90.5 MHz.

Teachers are living more and more cautiously, and the psychological burden they bear is getting heavier, which has led excellent teachers to be overwhelmed. They can only use resignation as a buffer and a breather, allowing themselves to retreat fully and embrace a new life.

Second point: offense is the best defense. Don't change a smash into a clear because you are afraid of mistakes or losing points, change a spike into a drop shot, or change a drive into a lift when receiving a smash. Why not take the initiative to attack? You should know that when you defend, you are always passive. As long as your opponent's technique is better than yours and more stable, even if your defense is good, sooner or later your opponent will find a weakness. Only by finding opportunities to attack more can you beat opponents whose technique is slightly better than yours. Relying solely on defense gives you no hope of winning!

Here, "we" refers to parents, schools, and students. After all, one hand cannot clap. Everyone must work together to reverse the various wrong trends that currently exist and make respecting teachers and valuing education a consensus again.

The teacher's resignation letter stated that he resigned for personal reasons. He is a senior teacher who has worked in teaching for thirty-one years, with only seven years left before retirement.

To describe brightness, first understand what brightness is. The eye can see something emitting light because it actually receives the electromagnetic wave energy emitted by that thing within the visible light wavelength range. The higher the energy received, the brighter it feels.

Teachers are the foundation of education. If teachers develop a negative and resistant attitude toward their own work, the path of education will be hindered and adversely affected.

No matter what problem a child has at school, parents never first consider whether the problem lies with their own child, but directly blame the teacher, treating the teacher as the target. It is really difficult for teachers.

  According to the scores of teacher and student representatives, the total score of the property management evaluation in May was 867, with an average score of 86.7, exceeding the minimum score of 85.

If you still can't understand after reading five times, change your approach. There is also a non-standard unit of luminous intensity called "candlepower" that can help you understand. 1 candlepower is approximately the light intensity emitted by a candle. 1 candela of luminous intensity equals 60 candlepower, meaning one candela is about the brightness of 60 candles. Isn't it so easy to understand this way? If you want to know how bright one candela is, buy 60 candles and light them up. Imagine that the candela is still quite a large unit.

In response to students' feedback on repair requests, environment, and other issues, and to further promote the construction of a beautiful campus, our school held a property management evaluation meeting on June 9. At the meeting, the property manager summarized the work from May to June, and teacher representatives and student representatives scored and asked questions.

   We raised this issue because of the strong response from the majority of students, so we want to provide students with a good space for playing and watching basketball. Due to lighting problems, many students who love basketball cannot confidently pursue their happiness in their free time. Moreover, if we use LED lights supported by most students, we can not only illuminate the court but also contribute to energy conservation and environmental protection. It both adds energetic young people to the court and responds to the national call, achieving the best of both worlds.

A: Because there is a risk of falling tiles upstairs and maintenance is difficult, the road needs to remain closed for a short time. Repairs are planned for the summer vacation.
