The potential energy of the charges due to the voltage between the terminals is converted to kinetic energy in the device. These devices are called passive components or loads; they 'consume' electric power from the circuit, converting it to other forms of energy such as mechanical work, heat, light, etc.
Answer:
time constant of the damping 130 seconds
Explanation:
given data
amplitude A1 = 1.6 m
time t = 1.5 min = 90 sec
amplitude A2 = 0.80 m
to find out
time constant of the damping
solution
we know here that maximum amplitude at time t is express as
A2 = A1 × e .............a
here b is time constant
so b will be from equation 1
b = ............b
put here all value top find b
b =
b =
b = 129.84
so time constant of the damping 130 seconds
Answer:
<em>The rebound speed of the mass 2m is v/2</em>
Explanation:
I will designate the two masses as body A and body B.
mass of body A = m
mass of body B = 2m
velocity of body A = v
velocity of body B = -v since they both move in opposite direction
final speed of mass A = 2v
final speed of body B = ?
The equation of conservation of momentum for this system is
mv - 2mv = -2mv + x
where x is the final momentum of the mass B
x = mv - 2mv + 2mv
x = mv
to get the speed, we divide the momentum by the mass of mass B
x/2m = v = mv/2m
speed of mass B = <em>v/2</em>
