Question

Мощьность велосипедного двигателя 700Вт. Какую работу он может совершить за 15 секунд?

Answer 1

Пусть N - мощность, А -работа, t -время работы

Мощность - это работа за единицу времени

 N = A:t, откуда

А =  N·t

А = 700·15 = 10500(Дж) = 10,5кДж

Ответ: работа, совершённая двигателем за 15 секунд, равна 10,5кДЖ

Answer 2

По формуле работы A=Nt найдем работу: A=700*15=10500Дж Ответ: 10500Дж

Answer 3

Calculation of Work Done by a Bicycle Motor

To calculate the work done by a bicycle motor with a power output of 700W over a period of 15 seconds, we can use the formula:

Work (W) = Power (P) x Time (t)

Given that the power output of the bicycle motor is 700W and the time is 15 seconds, we can substitute these values into the formula to find the work done.

Work (W) = 700W x 15s

Now, let's calculate the work done:

Work (W) = 10,500 Joules

Therefore, the bicycle motor with a power output of 700W can perform 10,500 Joules of work in 15 seconds.

Please note that the above calculation assumes that the power output of the motor remains constant throughout the 15-second period. Additionally, this calculation does not take into account any efficiency losses or other factors that may affect the actual work done by the motor.
