Pendulum Clock Works Earth Taken Moon Physics Question 10 Points?

Physics question 10 points? - pendulum clock works earth taken moon

A pendulum clock, which is very good on the work of the Earth to the Moon, where g = 1.63 m/s2. When the clock starts at 12:00 clock, what you read on the moon 24.0 hours on Earth?

T = 2π (L / G) ^ 0.5

T ≅ √ (1 / g)

T_moon = T_earth (g_earth / g_moon) ^ 0.5 = (9.8/1.63) ^ 0.5

T_moon = 2.452 T_earth

A pendulum started at 12:00, where on earth is 24:00 clock, while the moon at 12.00 clock + (24 - 12) / 2.452 = 16:54

Length of pendulum = 1 m

Period of a pendulum is given by

T = 2π (L / G) ^ (1 / 2)

Deadline for the full vibration 1 = 2.00607 ~ 2 sec; vibration Number = 43200

To the moon, g = 1.63

And used the formula, comes the time to 3.85 sec

After completion of the clock an hour (3600 / 2) = 1800 vibrations

In 24 hours, ie, 86,400 seconds completed this clock 86400/3.83 = 22441.551
And the time for the oscillation clock = 1800

Number of hours trying to spend about 24 hours on Earth = 22,441.551 / 1800 = 12.46 hours

I would say this about the 1230!
