When fat comes in contact with sodium hydroxide, it produces soap and glycerin. Determine whether this is a physical change or a
DochEvi [55]

A quick, easy way to decide whether there was a chemical change

is to look and see whether there are NEW substances after the

event, that weren't there when it started.

And then, suddenly, POOF ! Soap and glycerin showed up. Where did

What is the wave speed of a wave that has a frequency of 250 Hz and a wavelength of 0.35 m?
azamat

Answer:

87.5 m/s

Explanation:

The speed of a wave is given by

v=\lambda f

where

v is the wave speed

\lambda is the wavelength

f is the frequency

In this problem, we have

f=250 Hz is the frequency

\lambda=0.35 m is the wavelength

Substituting into the equation, we find

v=(0.35 m)(250 Hz)=87.5 m/s
