Difference between gravity and weight

there diferent duh. next time use 69 not 79

Explanation:

Weight is a quantity that you measure for a particular object, while gravity is a measure of how curved is the spacetime where that object is living.

Weight is measured is gram while gravity is measured in

newtons per kilogram.

Hope it helps :)

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
