Kepler's second law of planetary motion<span> describes the speed of a </span>planet<span> traveling in an elliptical orbit around the sun. It states that a line between the sun and the </span>planetsweeps equal areas in equal times. Thus, the speed of theplanet<span> increases as it nears the sun and decreases as it recedes from the sun.</span>
The formula to get the velocity is V=D/T. First you need to determine the distance and time at a certain point and plug it into the equation and that will be your velocity at that point. To get it between two points you complete the directions two times and find the average or use the slope formula, slope = rise/run; slope = (y2 - y1) / (x2 - x1).
Answer:

Also we know that for cyclic process change in internal energy is always ZERO
Explanation:
First gas is compressed isobarically such that its volume is half of initial volume
So its temperature is also half
So heat given in this process is given as

for diatomic gas we have

so we will have


Now in adiabatic process heat is not transferred
so in this process

so we have



Now it is again reached to original pressure
so temperature will become initial temperature
so heat given in that part

here we know that



So total heat given to the system is


Also we know that for cyclic process change in internal energy is always ZERO
