Weegy: Orbiting satellites and the orbit of the moon around the Earth have: Central-force motion in common.
User: A book, that has a mass of 0.5 kilograms, is pushed across a table with a force of 20 newtons. What is the acceleration of the book?
Weegy: The acceleration of the book is 40 m/s
User: Kepler modified Copernicus's model of the universe by proposing that the
Weegy: Kepler modified Copernicus's model of the universe by proposing that the Paths of the planets follow an elliptical orbit around the sun.
User: What do scalars measure?
Weegy: Scalars measure magnitude.
User: If the velocity of an object chances from 65 m/s to 98 m/s during a time interval of 12 s, what's the acceleration of the object?
Weegy: An object has a mass of 120 kg on the moon. the force of gravity acting on the object on the moon is 196N . Force = mass *acc, Force = 120 * 9.8 /6 = 196N
User: A person with a mass of 15 kg is walking downhill at a velocity of 10 m/s. What is the walker's momentum?
Weegy: A person with a mass of 15 kg is walking downhill at a velocity of 10 m/s. The walker's momentum is 150 kg-m/s.
Solution:
p=mv (mass*velocity) 15 kg* 10 m/s = 150 kg-m/s
User: While Kepler supported the Copernican model of the universe, Kepler concluded the following:
Weegy: While Kepler supported the Copernican model of the universe, Kepler concluded that all other bodies in the universe move around the earth in circular paths.
User: Which of the following statements is accurate?
Weegy: The amplitude of longitudinal waves is measured at right angles to the direction of the travel of the wave and represents the maximum distance the molecule has moved from its normal position -is an accurate statement. [ ]
User: Kepler's laws follow which law discovered by Sir Isaac Newton?
Weegy: Kepler's laws follow Sir Isaac Newton's laws of motion.
