Answer:
The normal force the ground exerts on the block, F = -300 N
Explanation:
Given data,
The block pulled up with a tension force, T = 100 N
The weight of the block, W = 300 N
The weight of the block is due to the force of attraction of gravitation.
The surface exerts a force that is equal and opposite to the force acting on the block due to gravitation.
The weight of the block,
W = mg
300 N
The normal force the ground exerts on the block,
F = - mg
= - 300 N
Hence, the normal force the ground exerts on the block, F = -300 N
If youre talking about plane mirrors: virtual, upright, left-right reversed, same distance from the mirror as the objects distance, and the same size as the object.
Answer:
They travel slower than P waves.
They result in much ground motion.
Explanation:
There are three types of seismic waves: P waves, S waves and Surface waves.
P wave are primary waves which require medium to travel. These are fastest waves. S waves are the secondary waves. These are transverse waves. S waves move slower than P waves. Both of these waves can travel through the inner layers of Earth.
Surface waves travel near the surface or above the surface of the Earth. These travel slower than S waves and P waves but have large amplitudes which could much ground motion and cause huge destruction.
Hence, the statements describe the surface waves:
They travel slower than P waves.
They result in much ground motion.
