The main resistive force that opposes the driving force when a vehicle is moving is Drag Force/ Air resistance. Air resistance is the frictional force exert by air on the moving body. Greater the velocity of the body, more it will experience air resistance. Air resistance tries to slow down the slow down the speed of the body. The force by engines tries to move it forward and drag force tries to move it in opposite direction. If the force by car engine is greater than the drag force, car will move forward.
The answer for the following problem is explained below.
<u>Therefore the change in the momentum is 240 kg m/s</u>
Explanation:
Given:
net force() = 120 N
time (t) = 2 seconds
To solve:
change in momentum(Δp)
We know;
= Δp÷t
Δp = × t
Δp = 120 × 2
Δp =240 kg m/s
<u>Therefore the change in the momentum is 240 kg m/s</u>
Answer:
F = qvB sinθ
(Hope this helps! Btw, I am the first to answer. Brainliest pls! :D)
Higher-level consumers get the most energy from food they eat.
An example is a lion eating a zebra. The zebra has more energy than a handful of grass, which has almost none to offer.
