The eaths radius is the correct answer, if you need proof look at nasa's website
Answer:
Contact forces are forces that require the actual contact (touching) of two pieces of matter. There are a variety of contact forces. A very common one is friction. Anytime that two surfaces are in contact with one another, there is friction between the two surfaces. A field force is a force that works at a distance. No touching is required. Gravity is a good example of a field force, because it works whether or not an object is touching something or touching nothing at all.
Answer:
1.75 kW
Explanation:
First, the rate at which work is done is simply termed Power
m = 35kg
v = 5.0 m/s
since the undergoes a vertical motion g = 10 m/s²
F = W = mg = 35×10 = 350 N
Power = Fv = 350×5 = 1750 Watt
C play all the songs on shuffle. entropy has to do with randomness
Among these, the greatest impact would have to be Newton's first law, the law of gravity. All of the planets stay in their own orbits, even if their orbits are not exactly perfect. This is done because of the sun's gravitational force, which keeps all of the planets in the solar system revolving around it.
