Lucrul mecanic :
- Se masoara in J(Joule)
- Se masoara in N(Newton)
- Se masoara in A(Amper)
Correct Answer

A. Se masoara in J(Joule)

Explanation

Lucrul mecanic se masoara in J (Joule) because Joule is the unit of energy in the International System of Units (SI). Work is defined as the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force. The Joule is a derived unit that represents the amount of work done when a force of one Newton is applied over a distance of one meter. Therefore, the correct unit to measure work is Joule.

Energia interna:
- Nu depinde de temperatura absoluta
- Este marime fizica de proces
- Este marime fizica de stare ce depinde temperatura absoluta
Correct Answer

A. Este marime fizica de stare ce depinde temperatura absoluta

Explanation

The correct answer is "Este marime fizica de stare ce depinde temperatura absoluta" which translates to "It is a physical state quantity that depends on absolute temperature." This means that the internal energy of a system is a property that is determined by the temperature of the system and not by any other factors.
