Will the time period of a spring change when vibrated with the same load on the surface of moon?

The acceleration due to gravity on the surface of moon is 1.7 m s^-2 . What isthe time period of a simple pendulum on the surface of moon if itstime period on the surface of earth is 3.5 s? (gon the surface of earth is 9.8 m s6-2 )

What will be the change in time period of a loaded spring when taken to moon?

How will the period of a simple pendulum change when its length is doubled?

An object weighs 10 N when measured on the surface of the earth. What would be its weight when measured on the surface of the moon?

A proton and an alpha -particle enter a uniform magnetic field perpendicularly with the same speed. How many times if the time period of alpha -particle than that of proton? Deduce the expression for the ratio of the radii of the circular paths of two particles.

The radii of curvature of he two surfaces of a lens are not the same .It forms image of an object.The surfaces of the lens facing the object and image are interchanged .Will the position of the image change ?
