Answer:
The velocity is
Explanation:
From the question we are told that
The frequency of the signal sent out is
The frequency of the signal received is
The speed of sound is
Generally the frequency of the sound received is mathematically represented as
where v is the velocity of the object
=>
=>
=>
=>
=>
Friction, lack/loss of kinetic energy
The Sun shines on the moon which then shines back on the earth. Also the stars but thats very minimal
The force applied on the spring to stretch it is 13.2 N.
Hooke's law is a law of elasticity discovered by the English scientist Robert Hooke in 1660 that states that the displacement or size of a deformation is directly proportional to the deforming force or load for relatively small deformations of an object. When the load is removed under these conditions, the object returns to its original shape and size.
According to Hooke's law, F = k*e
where F is the force on the spring
k is force constant
and e is extension
F = (110)*(0.12)
F = 13.2 N

The gravitational force between two objects is given by:
F = GMm/r²
F = force, G = gravitational constant, M and m are the masses, r = distance between the objects.
The force is dependent on only the masses of the objects and the distance between them. It is not dependent on the temperature of the objects.
