Question

Which of the following is mostly neglected while doing calculations for finding maximum work?

1 point

1)Option 1 KE

2)Option 2 PE

3)Option 3 both of the mentioned

4)Option 4 None of these

​

Answer 1

Answer:

The changes in kinetic energy and are potential energy very small, hence they are neglected.

Answer 2

The correct answer is (c) both of these.

The progressions in kinetic energy and potential energy are very minute, consequently, they are dismissed.

• So to augment the worth of work do you want to have 0 points among power and removal accordingly work done will be most extreme when the point among power and dislodging is 0 ie are in the same heading.
• This implies that when the power is applied on a body and the removal of the body happens toward the power applied then work done is greatest. So when theta=0°, work done is greatest.
• Berthelot proposed the "rule of greatest work" in which all synthetic changes happening without the mediation of outside energy incline toward the development of bodies or of an arrangement of bodies which free hotness.
