<span>The earth does no work on her if she's falling in the direction of frictional force. But suppose it does work on the woman i.e in the opposite direction, N. Then we have F = mg where g is acceleration due to grav. So F = 68 * 9.8 = 666.4 Newton. Then work done = force * distance = 666.4 * 100 = 666400</span>
Answer:
0.88 mm
Explanation:
Given
Wavelength of the atoms, λ = 502 nm = 502*10^-9 m
Radius of the screen away from the double slit, r = 1 m
We know that Y(20) = 11.4*10^-3 m
d = (20 * R * λ) / Y(20)
d = (20 * 1 * 502*10^-9)/11.4*10^-3
d = 1*10^-5 / 11.4*10^-3
d = 0.88 mm
Therefore, the distance of separation between the two slits is 0.88 mm
