The stretch of the spring is

The constant of the spring is k=15 N/m, so we can find the force produced by the weight by using Hook's law:

= Actual wavelength = 
= Relative permittivity = 1.44
The observed wavelength in the glass is given by

The wavelength lies in the range of green light.
Hence, the observed color of light is 
How planets look like,and maybe How the planets were created
Potential Energy (P.E) = Mass x
Acceleration due to Gravity x Altitude. Putting this value in the above equation we get, Dimensional Formula of
Potential energy= M1L2T-2.
