Question

Стальное сверло массой 100 гр нагрелось при работе от15 до 115 градусов.какая механическая работа была выполнена при этом?

Answer 1

сm(t2-t1)=Q

Q=Wмех   по закону сохр энергии

Wмех=10*с(стали) (с(стали воззми из таблицы или инета)

 

 

 

 

 

 

Answer 2

Calculation of Mechanical Work

To calculate the mechanical work done by the steel drill, we can use the formula:

Work = Force × Distance

In this case, the force can be calculated using the formula:

Force = Mass × Acceleration

Since the drill is not accelerating, we can assume the acceleration is zero, and therefore the force is also zero. Hence, the work done by the drill is zero.

Therefore, the mechanical work done by the steel drill in this scenario is zero.
