Answer 1

N=A*t
перкводим в си.
N=12*10^3*3*10^2=36*10^5Дж=3600кДж

Answer 2

Calculation of Power

To determine the power of a mechanism, we need to know the work done and the time taken. In this case, the work done is given as 12 kJ (kilojoules), and the time taken is 5 minutes.

Power is defined as the rate at which work is done. It can be calculated using the formula:

Power = Work / Time

Converting the time from minutes to seconds (1 minute = 60 seconds), we have:

Time = 5 minutes * 60 seconds/minute = 300 seconds

Substituting the given values into the formula, we can calculate the power:

Power = 12 kJ / 300 s

Now, let's calculate the power:

Power = 0.04 kW

Therefore, the power of the mechanism, over which the acting force performed 12 kJ of work in 5 minutes, is 0.04 kW.
