56.25J because the formula for kinetic energy is Ek=1/2 x mass x velocity^2
Ek= 1/2 x 0.5 x 15^2
= 56.25J
John Dalton laid the foundation for atomic theory.
Hope this helps!
Answer:
The wavelength of incident light is
Explanation:
The physicist Thomas Young established, through his double slit experiment, a relation between the interference (constructive or destructive) of a wave, the separation between the slits, the distance between the two slits to the screen and the wavelength.
(1)
Where is the distance between two adjacent maxima, L is the distance of the screen from the slits, is the wavelength and d is the separation between the slits.
The values for this particular case are:
Then, can be isolated from equation 1
(2)
However, before equation 2 can be used, it is necessary to express and d in units of meters.
⇒
⇒
Finally, equation 2 can be used.
Hence, the wavelength of incident light is
