Answer:
hypernova making a black hole, and merger of two neutron stars
The moon orbiting the Earth
Explanation:
The motion of the moon orbiting the earth is a circular motion. Circular motion is simply the motion of an object in circle at constant speed.
- A cannonball flying from a cannon is a projectile motion and not a circular motion.
- A car moving along a straight track is a linear/translational motion.
- Pendulum of a grandfather clock is a simple harmonic motion.

sEE BELOW
Explanation:
Well.....because the numbers are 'astronomical'....meaning VERY, VERY , VERY LARGE
Answer:
The speed is 1.52 m.
Explanation:
Given that,
Displacement =0.270 m
Distance = 0.130 m
Suppose a 0.321-kg mass is attached to a spring with a force constant of 13.3 N/m.
We need to calculate the angular velocity
Using formula of angular velocity

Put the value into the formula


We need to calculate the velocity
Using formula of velocity

Put the value into the formula


Hence, The speed is 1.52 m.
Answer:
Explanation:
Given
coefficient of kinetic friction
=0.34
inclination 
weight of block=51 N
(a) When block is moving upward friction force acts downward
thus

as block is moving with constant velocity thus
is zero



(b)When Block slides down the wall friction changes its direction to oppose the block
