Question

Обчисліть потужність механізму, який за 1 годину виконує роботу 2,4 МДж.​

Answer 1

Ответ:

Объяснение:

t = 1 год = 3600c

A =  2,4 МДж = 2.4*10^6 Дж

P = ?

P = A/ t = 2.4*10^6 / 3600 == 667 Вт

Answer 2

Calculation of Power

To calculate the power of a mechanism that performs 2.4 MJ of work in 1 hour, we can use the formula:

Power = Work / Time

Given that the work done is 2.4 MJ and the time taken is 1 hour, we can substitute these values into the formula to find the power.

Power = 2.4 MJ / 1 hour

To calculate the power, we need to convert the units to a consistent system. Let's convert the work from megajoules (MJ) to joules (J) and the time from hours to seconds.

1 MJ = 1,000,000 J 1 hour = 3,600 seconds

Converting the work: 2.4 MJ * 1,000,000 J/MJ = 2,400,000 J

Converting the time: 1 hour * 3,600 seconds/hour = 3,600 seconds

Now we can calculate the power:

Power = 2,400,000 J / 3,600 seconds

Simplifying the calculation:

Power = 666.67 watts

Therefore, the power of the mechanism that performs 2.4 MJ of work in 1 hour is approximately 666.67 watts.
