Answer:
12m/s
Explanation:
Given parameters:
Power = 6.5 x 10⁴W
Force = 5.5 x 10³N
Unknown:
The resulting velocity = ?
Solution:
The velocity of a body is related to force and power using the expression below;
Power = Force x velocity
Insert the parameters and solve for velocity
6.5 x 10⁴ = 5.5 x 10³ x velocity
velocity = = 12m/s
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
