Explanation:
K.E of A = 9 times K.E of B
Answer:B
Explanation:
Galilean transformation are only approximately correct,while Lorentz transformation are more exact
I think the answer maybe C
Answer:
120s^-1
Explanation:
v=12v
I=10A
and since rate is with time, therefore rate=energy/time.
H=IV
10×12=120/s
therefore the rate is 120s^-1
