B)rotation of earth because we rotate around the sun so when your area faces away from the sun it looks like the sun is setting in your point of view.
Answer:
t = 160 minutes
Explanation:
Given that,
Distance of Uranus from Sun is
We need to find the time taken by the light to go from sun to Uranus if the velocity of light is constant in free space and it is equal to c.
So,
Since, 1 minute = 60 seconds
t = 160 minutes
So, 160 minutes is taken by the light.
It pushes the currents to opposite sides
Momentum before collision = momentum after collision
McVc=(Mc+Mb)V
1200*15.6=(1200+1500)*V
18720=2700*V
V=18720/2700
V=6.9m/s
