The spring scale will read 559 Newton's or 125.7 pounds.
Because force always has a direction, it always works towards or against something.
you might know that force,
is rate of change of momentum i.e
force = m (v-u)/t
= (mv - mu )/ t
as we know momentum is a vector quantity so, the rate of change of momentum i.e Force would also be a vector quantity.
momentum = mass × velocity
velocity has a direction so,
momentum has also got a direction.
so, momentum is also a vector quantity.
Positive. The 1st object loses electrons and will thus have an imbalance of charge with loss of electrons.
Yes yes it will............
