Answer:
volume
Explanation:
it depends on the volume of the items
hope this helps
The answer here would be the force of gravity Hope I could help! :)
Answer:
2234.63
Explanation:
Work done per cycle by the engine is calculated as;

#Since volume doesn't change in the isochoric steps, there is no work done, hence:

#For an isothermal change of state(ideal gas):

#for the expansion process:



Hence, the engine does 2234.63J per second.
Answer:
The amplitude of the resultant wave will be 0.
Explanation:
Suppose the first wave has an amplitude of A. Its angle is given as wt.
The second way will also have the same amplitude as that of first.
After the reflection, a phase shift of π is added So the wave is given as

Adding the two waves give

So the amplitude of the resultant wave will be 0.
I would say its c
given a fixed volume, when volume decreases while mass remains constant
density increases ie temperature increases also
