Question

Part A On which of the following will a simplependulum that is 0.67 m long have thegreatest frequency?
1 Mars (g = 3.69m/s2)
Moon (g = 1.62m/s2)    
Venus (g = 8.87m/s2)
Mercury (g = 3.70m/s2)
Earth (g = 9.78m/s2)

Part B On Venus, which ofthe following simple pendulums will have thesmallest frequency? 2 A pendulum 2.35m long.
A pendulum 2.49m long.    
A pendulum 2.33m long.
A pendulum 2.97m long.
A pendulum 2.75m long. 1 Mars (g = 3.69m/s2)
Moon (g = 1.62m/s2)    
Venus (g = 8.87m/s2)
Mercury (g = 3.70m/s2)
Earth (g = 9.78m/s2)
1 Mars (g = 3.69m/s2)
Moon (g = 1.62m/s2)    
Venus (g = 8.87m/s2)
Mercury (g = 3.70m/s2)
Earth (g = 9.78m/s2)
1 2

Explanation / Answer

we know frequency f = ( 1/ 2) [ g / L ] earth have large g value So, a pendulum on earth have large frequency (b). whick pendulum have maximum length have minimumfrequency So, 2.97 m long pendulum have smallestfrequency
