Answer:
a) P1+P2
Explanation:
The magnitude of their combined momentum is just the addition of each momentum, because in this case of inelastic collision, the kinetic energy of the two cars are both converted to some form of energy because the velocity of both cars becomes zero, i.e., V=0, making P = mv = 0, this means the magnitude of P1 + P2 = 0.
Answer:
The temperature of hot reservoir is 669.24 K.
Explanation:
It is given that,
Efficiency of gasoline engine, 
Temperature of cold reservoir, 
We need to find the temperature of hot reservoir. The efficiency of Carnot engine is given by :
So, the temperature of hot reservoir is 669.24 K. Hence, this is the required solution.
