Answer:
A: Electromagnetic waves only
Explanation:
electromagnetic waves only
I just took the test, Hope it helps!
Momentum is 100 kg.m/s
given
mass, m = 5 kg
velocity, v = 20 m/s
To find : momentum (P)
We know that momentum is given by equation:
p = mv
= 5 kg x 20 m/s
= 100 kg.m/s
That`s is the answer, just check
