Their are things call solar tides which are the effects of the sun But it would be alot calmer with out the moon.
A > Is the correct answer :)
Kinetic energy is movement, thus movement would be a characteristic that allows an object to have kinetic energy
Answer:
The pressure is constant, and it is P = 150kpa.
the specific volumes are:
initial = 0.062 m^3/kg
final = 0.027 m^3/kg.
Then, the specific work can be written as:

The fact that the work is negative, means that we need to apply work to the air in order to compress it.
Now, to write it in more common units we have that:
1 kPa*m^3 = 1000J.
-5.25 kPa*m^3/kg = -5250 J/kg.
