Answer:

Explanation:
given,
number of cycle complete (f) = 116 cycles per minute
wavelength observed at 11 m in 1.5 m.


v = 7.33 m/s




The wavelength of the wave is equal to 
The force of gravity the masses exert on each other. If one of the masses is doubled , the force of gravity between the objects is doubled. Increases , the force of gravity decreases.
Answer:
from a lesser hight
Explanation:
because you need less force
hope its right if it is mark brainlyest ;)
