Answer: The work done on the object is 110 W
Explanation:
Work is defined as the force that is causing the movement or displacement of an object.
Mathematically,
where,
W = work done on the object
F = Force applied on the object = 55 N
d = displacement = 10 m
Putting values in above equation, we get:
Hence, the work done on the object is 110 W
λ=8 cm wavelength
f=? frequency of wave
v=λâ f
40=8â f
f=408
f=5 sâ1Â is the answerThe volume increases is right for apex
