Ummm...my best answer is that heat helps the molecules move around faster and that temperature is the measure of that heat or cold.
Using Newtons Second Law:
F = m×a
F = (0.25 kg)(-2 m/s²)
F = -0.5 N
<h2>The correct option is C</h2>
Because solar panels are man made so they can shut down, not move, break, etc...? Don’t judge me, it’s just a guess.
V= d/t, The answer is 0.83 km/m.
Answer:
Explanation:
In order to calculate the change of any quantity you must substract the initial value of that quantity from the final value of the same quantity.
The concept of momentum is defined as,
Momentum = mass×velocity
So we calculate the change of momentum as,
Momentum change = final momentum - initial momentum
= mv - mu =m(v-u)
Where v = final velocity
u = initial velocity
m = mass of the object
So to calculate the momentum change of the car,
Change in momentum of the car = 1000×(8-1) = 1000×7 = 7000 Ns
