Question

Задача фізика!!!Протягом 5хв механізм виконує роботу 18кДж.Яку потужність має цей механізм?

Answer 1

T=300 c     A=18000 Дж    P=?
===
P=A/t=18000/300=60 Вт
=======================

Answer 2

Calculation of Power

To calculate the power of a mechanism, we need to know the amount of work done and the time it takes to do that work. In this case, we are given that the mechanism performs work of 18 kJ (kilojoules) in 5 minutes.

To calculate the power, we can use the formula:

Power = Work / Time

Converting the time to seconds (since power is typically measured in watts, which is joules per second), we have:

Power = 18 kJ / (5 minutes * 60 seconds/minute)

Calculating this, we get:

Power = 18,000 J / 300 seconds

Simplifying, we find:

Power = 60 watts

Therefore, the power of this mechanism is 60 watts.
