In a balanced system, the total energy should always stay the same. The total energy is the sum of the potential and the kinetic energies. If the potential energy increases, then the kinetic energy should decrease. This happens to keep the system under a state of balance.
When plane is flying in tail wind condition we will have
Now during return journey we can say its would be head wind now
time = 2 + 1 = 2 hours
now add two equations
distance = 360 miles
now from above equation again
I guess it’s d) isobaric mate correct me if I am wrong :D
Power is the ratio between energy and time:
In our problem we have E=76 J and t=3.7 s. Therefore, the power is
Answer:
i think answer should be C
