Most of this water is locked up in ice, and another 20.9% is found in lakes. Rivers make up 0.49% of surface freshwater. Although rivers account for only a small amount of freshwater, this is where humans get a large portion of their water from.
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:
A.
Explanation:
If its at a height the Gratitude of it falling down with only Gravity if Any other Forces are acting on it so as Friction But Sideways.
An approximation used to measure building height is 10 feet per building level.
Converting from feet to meters using the equation:
1 ft = 0.3048m
10 ft = 3.048m
Multiplying that by 30 storeys, we get:
3 x 3.048m = 91.44m, which is near the answer of (3) 10^2 m or 100m.
Astrophysics is the answer
