Answer:
A - ¼ of the force
Explanation:
According to Pascal’s principle, there's an equation that relates the force to area ratios in hydraulic systems, provided that the pistons will be at the same vertical height and that the friction in the given hydraulic system is negligible. This formula is;
F1/A1 = F2/A2
Thus;
F1/F2 = A1/A2
Where F is the applied force and A is area of pad.
Now, we are told that the size of the pad is doubled. Thus;
If the initial radius is r, then the new radius is 2r
Thus;
F1/F2 = (πr²)/(π(2r)²)
F1/F2 = r²/4r²
F1/F2 = ¼
F1 = ¼F2
Thus, the answer is ¼ of the force
The Answer is B) Office of Human Services Emergency Preparedness and Response
The frequency of wave B is half the frequency of wave A
Explanation:
The wavelength, the speed and the frequency of a wave are related by the wave equation:
where
v is the speed of the wave
f is its frequency
is its wavelength
The equation can also be rewritten as
In this problem, we have wave A with wavelength and speed v, so its frequency is
Then we have wave B, whose wavelength is twice that of wave A:
And its speed is the same; Therefore, its frequency is
So, the frequency of wave B is half that of wave A.
