Answer: set up proportions
Explanation:
The kinetic energy (KE) is 250 J and the gravitational potential energy (GPE) is 392 J
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
Hey There!
The planet that takes shortest time to orbit the sun is Mercury because it is closest to the sun.
Thank You!
