Answer:
<h2>E) 52.5 cm</h2>
Explanation:
Step one:
given data
period T= 3 milliseconds= 0.003
velocity v= 175m/s
wave lenght λ=?
Step two:
we know that f=1/T
the expression relating period and wave lenght is
v=λ/T
λ=v*T
λ=175*0.002
λ=0.525m
to cm= 0.525*100
=52.5cm
The wavelength of the wave is E) 52.5 cm

Answer:
The answer to your question is: F = 70 pounds
Explanation:
To calculate the net force, only substract the left value to the right value.
F = F right - F left
F = 100 p - 30 p
F = 70 pounds
