Question

A pendulum clock that works perfectly on Earth is taken to the Moon. Assume that the free-fall acceleration on the Moon is 1.63 m/s2.

(b) If the clock is started at 12:00 midnight, what will it read
after 21.0 h? (Enter the time to the nearest minute.)

____ : ___ AM

Answer #1

The answer is in the images. Page number is mentioned at right top.

A pendulum clock that works perfectly on Earth is taken to the
Moon. Assume that the free-fall acceleration on the Moon is 1.63
m/s2.
(a) Does it run fast or slow there?
fastslow Neither, it runs the same as on
Earth.
(b) If the clock is started at 12:00 midnight, what will it read
after 17.6 h? (Enter the time to the nearest minute.)

(a) Your pendulum clock which advances 1.0 s for every complete
oscillation of the pendulum is running perfectly on Earth at a site
where the magnitude of the acceleration due to gravity is 9.80
m/s2. You send the clock to a location on the Moon where the
magnitude of the acceleration due to gravity is 1.65 m/s2. Does the
clock run fast or slow on the Moon?
(b) If the clock is started at 12:00 noon, what will it read...

A clock is constructed so that it keeps perfect time when its
simple pendulum has a period of exactly 1.000 s. The pendulum bob
has length L = 0.2480 m and, instead of keeping perfect time, the
clock runs slow by 1.502 minutes per day.
1. What is the free-fall acceleration (in m/s2) at
the clock's location? (Give your answer to at least 3 decimal
places.)
2. What length of pendulum bob (in m) is required for the clock
to...

A pendulum has a length 1 m and a mass 1 kg. Assume Earth free
fall acceleration equal to 10 m/s^2. When the pendulum oscillates,
the maximal deflection angle is +/- 1 degree.
a) If the pendulum moves to Jupiter, what would be the
period?
b) Suppose at time t=0 the pendulum passes the lowest point 1.10
What is the pendulum’s velocity at t=0?
c) What is the pendulum’s kinetic energy at t =0?
d) Sketch the deflection angle as...

1. Suppose at time t=0 the pendulum passes the lowest point.
a) What is the pendulum's velocity at t=0?
b) What is the pendulum's kinetic energy at t =0?
c) Sketch the deflection angle as a function of time between t
=0 and t = 10.
d) Sketch...
