-0 m/s
- average velocity=displacement/time
- the runners displacement is zero so her average velocity must be zero
A hurricane becomes more powerful by evaporating water from oceans
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
