Answer:
1) as far as I remember
Let's take 20 as vf (final velocity) and 11 as (initial velocity) and 4 as time
So we would use this formula a=vf-vi/t
So 20-11/4

Answer:
Force is applied to the point where the can can't handle it and starts to get crushed
Explanation:
Answer:
Gravitational force increases as the masses of the objects increase and decreases as the distance between the objects increases. Balanced forces acting on an object cause no change in the motion of the object. When unbalanced forces act on an object, the sum of the forces is not equal to zero.

Answer:
The centripetal acceleration of the satellite is
.
Explanation:
Given that,
The distance covered by a geosynchronous satellite, d = 42250 km
The time taken by the satellite to covered distance, t = 1 day = 24 hours
Since, 24 hours = 86400 seconds
Let v is the speed of the satellite. It is given by the total distance divided by total time taken such that :



v = 3072.5 m/s
The centripetal acceleration of the satellite is given by :



So, the centripetal acceleration of the satellite is
. Hence, this is the required solution.
