if the time period of an oscillation is tripled the frequency becomes ------------- of its original
Answers
Answer:
When an object is oscillating in simple harmonic motion in the vertical direction, its
maximum speed occurs when the object
(a) is at its highest point.
(b) is at its lowest point.
(c) is at the equilibrium point.
(d) has the maximum net force exerted on it.
(e) has a position equal to its amplitude.
Because the total energy is fixed at kA 2
/2, the maximum kinetic energy occurs at the
minimum potential energy, where x = 0. Thus, the maximum speed is at the equilibrium
position.
Any body moving with simple harmonic motion is being acted by a force that is
(a) constant.
(b) proportional to a sine or cosine function of the displacement.
(c) proportional to the inverse square of the displacement.
(d) directly proportional to the displacement.
(e) proportional to the square of the displacement.
The force law which gives rise to simple harmonic motion is F = -kx, so the force is
directly proportional to the displacement.
A system consists of a mass vibrating on the end of a spring. The total mechanical
energy of this system
(a) varies as a sine or cosine function.
(b) is constant only when the mass is at maximum displacement.
(c) is a maximum when the mass is at its equilibrium position only.
(d) is constant, regardless of the displacement of the mass from the equilibrium
position.
(e) is always equal to the square of the amplitude.
The total energy for a mass undergoing simple harmonic motion on a spring is kA2
/2.
This expression depends only on the amplitude, not the instantaneous position, so the
total energy is constant.
The period of a pendulum increases by a factor of four when transported to the surface
of the mythical planet Tundra. What is the gravitational acceleration on the surface of
Tundra compared to that on Earth?
(a) g/16 (b) g/4 (c) g/2 (d) 2g (e) 16g
The period of a pendulum is given by T = 2π (g/L)
1/2
, from which g ~ 1/T2
. Thus, if the
period increases by a factor of 4, the local gravitational acceleration must decrease by a
factor of 16.
A string under tension carries transverse waves travelling at speed v. If the tension in
the string is halved and the linear density of the string is doubled, what is the wave
Explanation:
hope it helps u mark me as brainliest and thanks me pls bro or sis and also follow me
Explanation:
as weknow time period is equal to =1/F (f is the frequency)
and frequency it 3 so time period will be 1/3
hope u get it
