Answer:
physics is the study of functions, systems and and the explainable reasons why they do what they do.
Answer:
<em>The green car had the greatest momentum</em>
Explanation:
<u>Momentum</u>
Momentum can be defined as "mass in motion" and is calculated as the product of the mass of the object by its velocity.
Being v the magnitude of the velocity and m the mass of the object, the momentum is calculated with:
p = mv
The green car had a mass of m1=1200 kg and crossed the finish line at v1=53 m/s. Hence, its momentum was:
p1 = 1200 Kg * 53 m/s = 63600 Kg.m/s
The red car had a mass of m2=1100 kg and crossed the finish line at v2=55 m/s. Hence, its momentum was:
p2 = 1100 Kg * 55 m/s = 60500 Kg.m/s
Since p1 > p2, then the green car had the greatest momentum
Answer:
Explanation:
Work required = q x V
where q is charge on electron and V is potential difference
= 1.6 x 10⁻¹⁹ x 12
= 19.2 x 10⁻¹⁹ J
A device used to initiate and control a sustained nuclear chain reaction.
I believe this is a true or false question. The answer is true. The reason we have seasons is because of the earths tilt. So without it, we would simply have a constant weather pattern. That's why it can get so cold around the North Pole, the tilt is most drastic there. So the real answer is that it depends on where you live. If you're on the equator, then no, not having a tilt won't impact climate much, but the further you are from the equator, the more change there would be.
