in the same direction as the wave
Explanation:
In a compression wave, the particles in the medium moves in the same direction as the wave source.
A wave is generally defined as a disturbance that transmits energy.
- There are two types of waves based on the direction through which they are propagated.
- Transverse waves are directed perpendicularly in the direction of propagation.
- Examples are electromagnetic waves.
- Longitudinal waves are parallel to their source. Examples are sound waves, p-waves.
- They are made up of series of rarefaction and compression.

Answer:
If gravity on Earth is increased, this gravitational tugging would have influenced the moon's rotation rate. If it was spinning more than once per orbit, Earth would pull at a slight angle against the moon's direction of rotation, slowing its spin. If the moon was spinning less than once per orbit, Earth would have pulled the other way, speeding its rotation.

Answer:
Specific gravity is 0.56
Explanation:
We know that
mass of water displaced by the wood is, m1( apparent mass when wood in air and lead is submerged in water) - m2(the apparent mass when wood and lead both are submerged in water)
= 0.0765 - 0.0452 = 0.0313 Kg
So the specific gravity of the wood is, = mass of wood / mass of water displaced by the wood
= 0.0175/0.0313
=0.56
