Answer:
24000kgm/s
Explanation:
Given parameters:
Mass of car = 1200kg
Velocity = 20m/s
Unknown:
Momentum = ?
Solution:
Momentum is the amount of motion a body possesses.
Momentum = mass x velocity
Now insert the parameters and solve;
Momentum = 1200 x 20 = 24000kgm/s
<span>Newton's third law is that for every action, there is an equal and opposite reaction.
A </span><span>Damage is not a part of physics, at least I don't think it is. </span><span>
B </span>Is just downright wrong. If anything, the smaller mass will be pushed forward with the heavier mass. <span>
C Sounds correct
D It'</span><span>s wrong, because the masses are not equal, or else they would stop.</span>
From the front door to his current position, Aaron's Distance is 4m. and his Displacement is 4m.
Distance is a measure of how far apart two objects or locations are using numbers. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage. Sometimes, the symbol |AB| is used to represent the distance between two points.
A displacement is a vector in geometry and mechanics that have a length equal to the shortest distance between a point P's initial and final positions.
Given,
Length of path = 4m
Distance =?
Displacement =?
Distance is the length of the path and it has magnitude but no direction. The distance covered is 4m Displacement is the length of the path and it has magnitude and direction. Displacement is 4m towards the mailbox.

As the temperature of the lead and helium is the same. Thus the average kinetic energy is also the same for lead and helium.
Reason:
It is given that a 5.0-kg bar of lead is placed inside a 12-L chamber filled with helium gas. The temperature of the lead and helium is the same. It is required to compare the average kinetic energy of the lead atoms and helium atoms.
The average kinetic energy is calculated as, 
.
Here K is the average kinetic energy, R is the gas constant, N is the Avogadro's number, and T is the temperature.
As the temperature is the same for both lead and helium. As a result, the average kinetic energy is also the same for lead and helium.
