Explanation:
The gravitational potential energy gets transformed into translational and rotational kinetic energy, so we can write . Since
(the ball rolls without slipping) and for a solid sphere
, we have:
So our translational speed will be:
Answer:
Explanation:
Given
Wavelength of radiation
We know Energy of wave with wavelength is given by
where h=Planck's constant
c=velocity of light
=wavelength of wave
Hence the energy of the wave with wavelength 784 m is
