Answer:
2000 kg
Explanation:
Given that Which will have a larger momentum when moving at the same speed: a 2,000-kg truck or a 1,000-kg sedan
According to the definition of momentum, momentum is the product of mass and velocity.
That is,
Momentum = mass × velocity
Since velocity or speed is the same, then, the one of higher mass will have a greater momentum.
Therefore, the 2000 kg truck will have the greater momentum.

Answer:
A. Earth's gravity pulling down on air molecules
Explanation:
Air pressure refers to the weight of the air per unit surface area. It is the amount of gravitational force which is pulling down the molecules of air.
The common unit of air pressure is: Pascal, atm
1 atm = 101325 Pa
As the column of the air above increases, the air pressure increase. This is because with the increase in amount of air, the weight increase of the air increases. This is the reason a diver feels immense pressure in the sea and cooking takes a lot of time on hilly areas because of low air pressure.
Answer:
Yes! Light from the sun can affect the materials certain carpets are made out of. The usual effect being the dye in the carpet being "washed out" or "dried out" as the sun beams down on it. When this happens, the carpet will usually lose its color, causing it to fade.
