What happens to internal energy when mechanical work is done?
When mechanical work is done, the internal energy of a system can change. If work is done on the system, the internal energy increases. Conversely, if work is done by the system, the internal energy decreases. This change in internal energy is governed by the first law of thermodynamics.
A crate is pulled across a horizontal floor by a rope At the same time the crate pulls back on the rope in accord with Newton's 3rd law Does the work done on the crate by the rope then equal zero?
No, the work done on the crate by the rope is not zero. The work done is equal to the force exerted by the rope multiplied by the distance the crate is pulled. The fact that the crate pulls back on the rope in accordance with Newton's Third Law does not cancel out the work done by the rope.
Why can't the work done by a machine be greater than the work done on the machine?
According to the law of conservation of energy, energy cannot be created or destroyed, only transferred. Therefore, the work done by a machine cannot be greater than the work done on it because the input work is what provides the energy for the output work. Any excess work would violate this principle.
What is the relationship between mechanical energy and work?
Work is the quantity of energy being transfered (i.e. potential to kinetic). It is due to work that energy is transfered between potential and kinetic and vice versa. This is an attribute of the first law of thermodynamics. Energy is also the ability to do work
Is in the adiabatic process change in internal energy is equal to change in work done?
In an adiabatic process, where there is no heat exchange with the surroundings, the change in internal energy is equal to the negative of the work done. This relationship is a result of the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.
What type of law is passed after the deed is done?
The type of law that that is passed after the deed is done is called an ex post facto law. These are expressly forbidden by the Constitution.
Is work involed in newtons second law?
No, his three laws do not directly address work done.
What is a law that makes unlawful something that was not illegal at time it was done?
It is called an "ex post facto" law.

What is meant by a registered firearm?
Paper work done IAW local, state or federal law.
What is the possessive form of brothers in law?
The possessive form for the plural noun brothers-in-law is brothers-in-law's.Example: I had the work done at my brothers-in-law's body shop.
What was an American state where slavery is not allowed by law called?
An American state where slavery was not allowed by law was called a "free state." These states did not permit the practice of slavery within their boundaries, in contrast to states where slavery was legal.
Which law states that thermal energy increases depend on the work done and the heat added?
Conservation of energy.
How long does it take to get rid of a law after it has done its work?
Only by an act of Congress, both literally and figuratively .
How much free time does a law school student have?
That will depend on if they are working or not. Some people work full time and attend law school.
Is it against the law to ask people on the street if they want to work as an artists model?
That is not against the law. It would be considered a form of free speech.
