How to measure the speed of sound in air?

1 answer:

8 0

STEP ONE:

Let you and your friend stand as far away as possible from a large reflecting wall and clap your hands rapidly at a regular rate.

STEP TWO:

Adjust this rate until each clap just coincides with the return of an echo of its predecessor, or until clap and echo are heard as equally spaced.

STEP THREE:

Use a stopwatch to find the time between claps, t. Make a rough measurement of distance to the wall, s. Thus the speed of sound, v = 2s/t

A point source emits electromagnetic energy at a rate of 100 W. The intensity 10 m from the source is

MariettaO [177]

Answer:

$I=0.0795\ W/m^2$

Explanation:

Given that,

Power of electromagnetic energy, P = 100 W

We need to find the intensity at a distance of 10 m from the source. Intensity is equal to the power per unit area. So,

$I=\dfrac{P}{4\pi r^2}\\\\I=\dfrac{100}{4\pi (10)^2}\\\\I=0.0795\ W/m^2$

So, the intensity at a distance of 10 m is $0.0795\ W/m^2$

This will be due to the Effects known as 'Moments'
The person who is moving towards the centre will distribute its weight towards the centre causing the end of the see saw to be lighter.
