Answer:
It increases and is perpendicular to the motion of the wave.
Explanation:
- A transverse wave is a wave in which the oscillation occurs in a direction perpendicular to the motion of the wave (example of transverse waves are electromagnetic waves)
- A longitudinal wave is a wave in which the oscillation occurs in a direction parallel to the motion of the wave (example of longitudinal waves are sound waves)
- The amplitude of a wave is defined as the maximum displacement of the wave relative to the equilibrium position, and the energy carried by the wave is proportional to the square of the amplitude:
Therefore, as the amplitude of the wave increases, the energy increases as well.
Answer:
Explanation:
Given:
<u>Now the radius of revolution of the ball:</u>
<u>Now in this case the centrifugal force is equal to the spring force:</u>
where:
m = mass of the ball
k = spring constant
<u>Now the extension in the spring upon hanging the ball motionless:</u>
Answer
Pressure, P = 1 atm
air density, ρ = 1.3 kg/m³
a) height of the atmosphere when the density is constant
Pressure at sea level = 1 atm = 101300 Pa
we know
P = ρ g h
h = 7951.33 m
height of the atmosphere will be equal to 7951.33 m
b) when air density decreased linearly to zero.
at x = 0 air density = 0
at x= h ρ_l = ρ_sl
assuming density is zero at x - distance
now, Pressure at depth x
integrating both side
now,
h = 15902.67 m
height of the atmosphere is equal to 15902.67 m.
