Suppose you wanted to produce a sound wave with a wavelength of 1m
in room temperature air. What would its frequency be? *

340 Hz

Explanation:

The frequency of a wave is the number of oscillations completed by the wave per second.

For a wave, the relationship between wavelength of the wave and its frequency is given by the wave equation:

where

v is the speed of the wave

f is its frequency

is its wavelength

In this problem, we have a sound wave, with wavelength of

The speed of sound waves at room temperature is

Therefore, using the previous equation, we can find the frequency of the wave:

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
