Answer:
D
Explanation:
The rubber rod having been rubbed with fur get a net negative charge thereby gaining more mass which means the mass has increased compared to before it was rubbed against the fur while the glass rod having been rubbed with the silk to give it a net positive has lost mass and therefore has less mass compared to before it was rubbed on the silk.

Answer:
A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept
Explanation:
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
