Neutral charge, because neutron means neutral
Momentum is a product of mass and the velocity thus the momentum will be 5100*12 = 61200 kgm/s
Answer:
velocity = distance / time
Explanation:
Answer:
ω' = 2.5 rad/s
Explanation:
mass of cockroach, m = 4 kg
mass of disk, M = 6 kg
Radius of disc= R
initial angular velocity, ω = 2 rad/s
Let the final angular velocity is ω'
As no external torque is applied, so the angular momentum is constant.
Angular momentum = Moment of inertia x angular velocity
I ω = I' ω'


ω' = 2.5 rad/s
