Answer:
The equation of motion is
Explanation:
Lets calculate
The weight attached to the spring is 24 pounds
Acceleration due to gravity is
Assume x , is spring stretched length is ,4 inches
Converting the length inches into feet
The weight (W=mg) is balanced by restoring force ks at equilibrium position
mg=kx
⇒
The spring constant ,
= 72
If the mass is displaced from its equilibrium position by an amount x, then the differential equation is
Auxiliary equation is,
=
Thus , the solution is
The mass is released from the rest x'(0) = 0
=0
Therefore ,
Since , the mass is released from the rest from 4 inches
inches
feet
feet
Therefore , the equation of motion is
Answer:
Part(a): The frequency is .
Part(b): The speed of the wave is .
Explanation:
Given:
The distance between the crests of the wave, .
The time required for the wave to laps against the pier,
The distance between any two crests of a wave is known as the wavelength of the wave. So the wavelength of the wave is .
Also, the time required for the wave for each laps is the time period of oscillation and it is given by .
Part(a):
The relation between the frequency and time period is given by
Substituting the value of in equation (1), we have
Part(b):
The relation between the velocity of a wave to its frequency is given by
Substituting the value of and in equation (2), we have
At what angle torque is half of max
Answer:The disturbance created by a source of sound in the medium travels through the medium and not the particles of the medium
Explanation:i hope this is right
A) amperes
B) current.
C) gravity.
D) voltage.
correct. D) Voltage is the change in electric potential energy per unit charge. It is sometimes called the electric potential difference
