Answer:
L = I α t
Explanation:
given,
rotational inertia = I
initial velocity = ω₀
magnitude of acceleration = α
angular momentum = L
time = t
angular acceleration
ω = α t..............(1)
angular momentum
L = I ω
putting value from equation (1)
L = I α t
Answer:
Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another.
