Answer: 248 Newton
Explanation:
force = rate of change of momentum
change of velocity
= 4 + 4 = 8 m/s
rate of change of momentum = mass per second x change of velocity
= 31 kg/s x 8 m/s
= 248 kg m/s^2 or Newtons
Answer:
300 J
Explanation:
Work = (Force)*(distance) = 600 N ∗ 0.5 m = 300 J
Answer:
Wavelength is 0.33 nm for n=1, 1.32 nm for n=4, and 3.3 nm for n=10.
Explanation:
The velocity of the electron in the nth level of hydrogen atom is,
Now the de Broglie wavelength can be calculated as,
For n=1 the wavelength is,
Therefore wavelength for n=1 orbit is 0.33 nm.
For n=4 the wavelength is,
Therefore wavelength for n=4 orbit is 1.32 nm.
For n=4 the wavelength is,
Therefore wavelength for n=10 orbit is 3.3 nm.
When light passes through a prism<span> the </span>light<span> bends. As a result, the different colors that make up white </span>light<span> become separated. This </span>happens<span> because each color has a particular wavelength and each wavelength bends at a different angle.</span>
