Since the spacecraft is two earth radii the surface of the earth, it is three earth radii above the center.
Given: Radius of the earth re = 6.38 x 10⁶ m r = 1.91 x 10⁷ m
Mass of the spacecraft Ms = 1600 Kg
Mass of the earth Me = 5.98 x 10²⁴ Kg
G = 6.67 X 10⁻¹¹ N.m²/Kg²
Formula: F = GMeMs/r²
F = (6.67 X 10⁻¹¹ N.m²/Kg²)(5.98 x 10²⁴ Kg)(1,600 Kg)/(1.91 x 10⁷ m)²
F = 6.38 X 10¹⁷ N/3.65 X 10¹⁴ m²
F = 1,748.5 N
The slope of the distance/time graph is the speed of the moving object.
So the graph for a fast moving object will have a greater slope than the
graph for a slower moving object has.
Answer: Car brakes produces more energy then the bicycle because the cars wheels produces a much bigger force that makes the car go and to stop that force the car uses greater amount of energy that transfers to heat but in a bicycle the wheels do not turn that fast so when you press the break there is less energy that transfer to heat.
Explanation:
Officials in the House of Representives have are able to serve a 2 year term and there are no limits as to how many terms.
Answer:
The molecule of gases are separated at far distance from each other in space causing the objects to move freely resulting in the increase in kinetic energy of the molecules.
Explanation:
There are 3 states of matters namely; solid, liquid and gaseous state.
For gases, the molecules are held father apart as such they possesses weak intermolecular force due to the large distance between their molecules. Due to the free nature of this molecules, they are free to move about in space leading to the increase in their kinetic energy. This molecules also tends to collide with one another and the walls of their container causing an increase in their kinetic energy and causing them to move faster in space.
