Answer:
The workdone is
Explanation:
From the question we are told that
The initial Volume is
The final volume is
The external pressure is
Generally the change in volume is
Substituting values we have
Generally workdone is mathematically represented as
W is negative because the working is done on the environment by the system which is indicated by volume increase
Substituting values
Now
Therefore
Answer:
sweeps out equal areas in equal times.
Explanation:
As we know that there is no torque due to Sun on the planets revolving about the sun
so we will have
now we have
now we also know that
so rate of change in area is given as
so we will have
since angular momentum and mass is constant here so
all planets sweeps out equal areas in equal times.
