Question

Какую работу совершает вентилятор за 10 минут,если его мощность равна 30 ВТ?

Answer 1

A=Nt = 30 Вт * 600 с = 18000 Дж= 18 кДж 

Answer 2

Calculating the Work Done by a Fan

To calculate the work done by a fan in 10 minutes, we can use the formula:

Work (W) = Power (P) × Time (t)

Given that the power of the fan is 30 W and the time is 10 minutes, we can calculate the work done.

Using the formula, we have:

Work (W) = Power (P) × Time (t) W = 30 W × 10 min

Converting the time to hours: 10 minutes = 10/60 hours = 1/6 hours

So, the work done by the fan in 10 minutes is: W = 30 W × (1/6) hours

Let's calculate the work done.
