某电热杯的铭牌如表所示．在一次烧水的过程中，加在电热杯两端的实际电压只有额定电压的0.9倍，烧开这杯水的时间为5min．若在使用的过程中电热杯的电阻保持不变，求：

（1）这次烧水过程中电热杯的实际功率是多少？

（2）如果电热杯在额定电压下工作，那么烧同样多的开水需通电多长时间？（设烧开这杯水需要吸收的热量不变且不计热量损失）

阅读理解。

     The person behind you constantly kicks the back of your seat. Your talkative seatmate doesn't understand

your need for sleep. And the aircraft's bathroom is a total mess. These situations can make even a short flight

unbearable. Hopefully you don't cause these unpleasant experiences for others. Instead, you can set an example

by following these common airplane courtesies.

     Always recline your seat slowly. There's nothing worse than suddenly being slammed in the knees by the

seat in front of you. In addition, don't keep your seat reclined for the entire flight. Always keep it upright

position before going to the restroom (or anytime you leave your seat).

     Avoid going to the bathroom during mealtime. Wait until the meal is done and all the food trays have been

collected. It's hard for passengers to stand up to let you pass when they still have their food trays. And when

using the bathroom,always clean up after your-self-the next user will be grateful!

     Keep your body-and your possessions-to yourself as much as possible so as not to crowd your in-flight

seatmate(s). Share the armrest, especially on a long flight. Also, be careful not to kick or push on the seat in

front of you, and don't allow your children to do so either.

     While some people enjoy chatting with other passengers during a flight, not everyone does. Some people

may want to nap, read or work. If the conversation seems one-sided, take the hint.

     If you are traveling with someone and want to chat,keep your voices low. If using electronic gadgets,

keep the volume down. People can still hear through your headphones if the volume is too high.

     When exiting the plane, if others are having trouble with their carry-on luggage, help them if you can.

If you can't help, wait patiently, and don't push past people to get off the airplane.

     On your next flight, remember that it all boils down to the golden rule. Treat others the way you want

to be treated!
