Answer:
false
Explanation:
A vector quantity is the magnitude of a given quantity? True Or False
Answer:
Given:
mass of the ball m = 0.144 kg
velocity v = 38 m/s
now, change in momentum
P = m v- ( - mv)
= 2 mv
=2 x (0.144) x (38)
= 10.944 kg-m/s
Impulse J= F. Δt
change in momentum is equal to impulse
J = 10.944 kg-m/s
we know force is equal to change in momentum per unit time


F = 13.68 x 10³ N
F = 13.68 kN
Answer:
(C) Radiation
Explanation:
The weak nuclear forces causes radiation to form.
The correct response would be C. Carpenter hammering a nail. The carpenter is applying a force as he or she is hitting the surface of the nail with the hammer.
