Two electrons, each with mass mmm and charge qqq, are released from positions very far from each other. With respect to a certai
n reference frame, electron A has initial nonzero speed vvv toward electron B in the positive x direction, and electron B has initial speed 3v3v toward electron A in the negative x direction. The electrons move directly toward each other along the x axis (very hard to do with real electrons). As the electrons approach each other, they slow due to their electric repulsion. This repulsion eventually pushes them away from each other.
What is the minimum separation r_min that the electrons reach?

Answer:
gas is dioatomic
T_f = 330.0 K
Explanation:
Part 1
below equation is used to determine the type Gas by determining value
where V_i and V_f is initial and final volume respectively
and P_i and P_f are initial and final pressure
\gamma = 1.38
therefore gas is dioatomic
Part 2
final temperature in adiabatic process is given as
substituing value to get final temperature
T_f = 330.0 K
Part 3
determine number of moles by using following formula
As per energy conservation in the reversible engine we can say
here we know that
now from above equation
now we can convert it into kW
so above is the power input to the refrigerator
now to find COP we know that
so COP of refrigerator is 2.2
