Explanation:
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction
The time component is needed. The acceleration is the change of velocity divided by the time in when this change of velocity happens.
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.
Answer:
d. circuit
Explanation:
the parts of the circuit consists of a load or resistance
It is called surface tension it is the elastic personality of some liquids as they pull together to take up as little surface area as possible. the water molecules would rather stay together than be pulled apart<span />
