Answer:
Newton's Second Law of Motion states that a force on an object is equal to the mass of the object multiplied by its acceleration (F=ma). ... When the punter kicks the ball, his foot exerts a force on the ball. The football then exerts an equal amount of force in the opposite direction on the kicker's foot.
Wave speed (m/s) = frequency (Hz) x wave length (m)
=0.2 x 100= 20m/s
Answer:
second law
Explanation:
Newton's second law explains how much motion a force creates.
Geocentric Theory
In astronomy, the geocentric model is a superseded description of the Universe with Earth at the center. Under the geocentric model, the Sun, Moon, stars, and planets all orbited Earth
Heliocentric Theory
Heliocentrism is the astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center
G-Theory is the earth is the center of the universe.
