Answer:
a person pushes water with his hands in the backward direction is action and water in turns pushes him forward due to force is reaction.
Explanation:
Answer:
The force of friction is 2 N. The object isn't moving.
Explanation:
The frictional force on a object is given by it's normal force multiplied by the coefficient of static friction between the object and the surface. In this case since the surface is horizontal, the normal force is equal to the weight of the block with the oposite direction. So we have:
F_friction = 0.5*N = 0.5*(10) = 5 N
Since the friction force is oposite to force that's acting on the block and it's greater than that force, the object won't move and the real force will be the same as the applied force. So we have:
F_friction = 2 N
The first one, his laws helped explain the motion of objects in the universe.
Answer:
decreases, but frequency increases.
Explanation:
Wavelength and frequency are inversely proportional, meaning the higher the frequency, the shorter the wavelength, and the lower the frequency, the longer the wavelength.
