According to Newton's second law of motion, the force of the object applied to accelerate is equal to the mass of the object multiplied by the acceleration. However in reality, air friction are still considered. In this case, if the density of air is 0, hence vacuum and air is negligible, then mass and radius is proportional to the acceleration.
Answer:
a) Species change over time; some traits become more common, others less. This process of change is driven by natural selection. The traits that become more common are the ones that are “adaptive” or “increase fitness” (that is, a creature's chances of living longer and producing more offspring)
Explanation:
because it is
<span>By F = ∆P/∆t
=>F = n x m x ∆v/∆t
=>F = [242 x 66.1 x 10^-3 x 488]/3.57
=>F = 2186.60 N
By the law of momentum conservation:-
=>(M+m)V = Mv1 + mv2
=>(3630 + 66.1 x 10^-3 x 242) x V = 3630 x v1 + 66.1 x 10^-3 x 242 x 488
=> if we know the initial speed i.e. V we can calculate final speed v1.</span>
The answer would be velocity because its stating the speed and direction of the car.
Answer:
Both experienced the same magnitude impulse
Explanation:
This is because, the impulse force is internal to the system of both the tennis ball and the bowling ball. It is an action-reaction pair. So, the force exerted on the tennis ball by the bowling ball equals in magnitude to the force exerted by the tennis ball on the bowling ball although, they are in opposite directions. This, both experienced the same magnitude impulse.
