Answer:
d. The hammer falls with a constant acceleration
Explanation:
Since gravity is the only thing that is acting on the hammer as it falls and gravity is a form of acceleration then acceleration of 9.81m/s² which is gravity is the correct answer.
The heavier object has a higher kinetic energy. Kinetic energy is the energy possessed by a body when in motion. It is given by 1/2 mv², where m is the mass and v is the velocity. At a constant velocity, increase in mass increases the kinetic energy. Therefore an object with heavier mass would have higher kinetic energy compared to the lighter energy.
I think the best answer that could be fit to this question and according to the statement that the balloon is moving west so it means that the wind was blowing from east to west in the equator, since the moving of the balloon only affects on the wind pressure that could blown it.
that's cause the roller coaster loses energy to other forces as it does loop-the-loops, curves, and other hills along the way
Answer:
changes
Explanation:
According to Michael Faraday, voltage is induced on a metallic conductor when the magnetic field changes. The principle is known as the principle of electromagnetic induction. The voltage induced on the metallic conductor is referred to as induced emf.
The magnitude if induced emf depends on the rate of change of the magnetic flux.
