Two events are observed in a frame of reference S to occur at the same space point, with the second event occurring after a time
of 1.70 s . In a second frame S' moving relative to S, the second event is observed to occur after a time of 2.25 s . What is the difference between the positions of the two events as measured in S'?

Explanation:
The concept of root mean square velocity is applied, where the average translational kinetic is related to the actual kinetic energy, the expression for the root mean square is the generated.
The detailed steps and appropriate substitution is as shown in the attachment.
Answer:
Explanation:
We are given that
Work done by the system= J
Heat transfer into the system= J
Heat transfer to the environment= J
We have to find the change in internal energy
By first law of thermodynamics
Substitute the values then we get
Hence, the change in internal energy =
