during the morning walk a boy Run along the side of a square field if side is hundred metre long what is the maximum magnitude of displacement of the boy in any time interval​

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

e/c, where e is its total energy

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
