You need to learn the equations:


        Applied force = spring constant x extension

        Elastic Potential Energy = x spring constant x (extension)2

        Wave speed (m/s)  =  frequency (Hz)  X  wavelength (m)

        Frequency = 1/time period

        Efficiency = useful energy output / total energy input

        Power  (W)  =  energy used (J)  /  time taken (s)

        Heat Energy Supplied  =  mass X specific heat capacity X temperature rise    

        Heat transferred (J)   mass of substance (kg) x specific latent heat (J/kg
