Answer:
3
Explanation:
From the question given above, the following data were obtained:
Length (L) = 3 m
Height (H) = 1 m
Mechanical advantage (MA) =.?
The ideal mechanical advantage for the system can be obtained as follow:
MA = L/H
MA = 3/1
MA = 3
Therefore, the ideal mechanical advantage for the system is 3

Answer: 529.9 Hz
Explanation:
Here we need to use the Doppler equation, so we have:
f' = f*(v + v0)/(v - vs)
Here, f is the frequency = 500Hz
v is the velocity of the wave, = 334m/s
v0 is the velocity of the observer = 20m/s
vs is the velocity of the source = 0m/s
Then we have:
f' = 500Hz*(334m/s + 20m/s)/(334m/s) = 529.9 Hz
The answer is B. Remain still.
