So if the formula for work is force times displacement times cosine(theta), you'd plug in the numbers
100x5 (since there's no angle in the problem, cosine(theta) isn't used
100x5 = 500
So the answer would be B.
Hope that helps!
Answer:
Speed = 0.296m/2
Period = 0.203 s
Explanation:
If by 'long' you mean the wavelength of the waves, then the wavelength
.
The frequency
of the waves is 14.8 waves every 3 seconds or
.
Now the relationship between wavelength
, frequency
and speed
of the waves is:

We put in the values
and
and get:
Now the period
is just the inverse of the frequency, or


If the stereo has a dial that changes the volume of the sounds the stereo makes, the one that being done by the dial is : D. Changing the amplitude of the sound waves
