A meteor is the flash of light that we see in the night sky when a small chunk of interplanetary debris burns up as it passes through our atmosphere. "Meteor" refers to the flash of light caused by the debris, not the debris itself.

If any part of a meteoroid survives the fall through the atmosphere and lands on Earth, it is called a meteorite.

A student blows in a tube with one closed in that is 0.49 m long. If the frequency of the sound is 358 Hz what is the speed wave

BaLLatris [955]

Answer:175.42m/s

Explanation:

Wavelength=0.49m

Frequency=358Hz

Velocity=frequency x wavelength

Velocity=358x0.49

Velocity=175.42m/s

Which wave, A or B, has lower energy? A, because it has a higher amplitude B, because it has a higher amplitude A, because it ha

frutty [35]

Energy of wave depends on its amplitude and it is given as

$E = \frac{1}{2} kA^2$

here k = constant

A = amplitude

so energy will increase or decrease depends on the amplitude of the wave

So here if we need to check which wave has lower energy then we need to compare the amplitude.

If the amplitude is less then energy must be less

So please check in the figure that which wave out of A and B has lesser amplitude to find out the wave of lesser energy
