Answer:
Explanation:
Given
mass of satellite
orbital radius
mass of Earth
Minimum amount of Energy to move Satellite from its orbit to an infinite distance is sum of Potential Energy + Kinetic Energy of Satellite
Where
i.e. Energy is required to provide to move Satellite out of its orbit
Answer:
A little over a second
Explanation:
gravity pulls down on objects at a speed of 9.8 meters a second
Heat always flows from higher temperature to lower temperature. So option A. heat will flow from the air into the coolant is the correct answer.
<h2>
Tension in tow line is 2000 N</h2>
Explanation:
Power is the ratio of work and time.
Work = Force x Displacement
W = F x d
Here force is tension, T
So
W = T x d
Substituting
We have
Power, P = 30kW = 30000 W
Velocity, v = 15 m/s
Substituting
30000 = T x 15
Tension, T = 2000 N
Tension in tow line, T = 2000 N
