Question

At what rate will a pendulum clock run on Saturn, where the acceleration due to gravity is 11.2 m/s^2, if it keeps time accurately on Earth? That is, find the time (in hours) it takes the clocks minute hand to make one revolution on Saturn. _______ hours


Ultrasound of intensity 1.50 x 10^2 W/m^2 is produced by the rectangular head of a medical imaging device measuring 3.00 cm by 4.00 cm. what is the power output? _________W At what rate will a pendulum clock run on Saturn, where the acceleration due to gravity is 11.2 m/s^2, if it keeps time accurately on Earth?

Explanation / Answer

1)

For a second's pendulum, T = 2 s
So, L = 0.994 m

Now, T' = 2 * pi * [0.994 / 11.2]^0.5 = 1.87 seconds
So, 60 swings will occur in 30*T = 56.1 sec

So, 1 hr as per the clock will be 0.935 earth hours long   

2)

Power = intensity *area = 1.50 x 10^-2 *(3*4)

Power = 180 *10^3 Watt =180 KW
