Under Ideal Gas Law, "pressure" is<u> directly proportional to the number of molecules</u> (provided that the volume and temperature remains constant).
Most of the atmosphere's molecules are drawn towards the surface of the Earth because of "gravity." This means that there are <u>more atmospheric molecules closer to the Earth's surface,</u> which also means the air pressure in lower altitude is higher due to a denser air space.
This, in turn, leaves a <u>lesser number of atmospheric molecules as the height increases</u> which means there is lesser atmospheric pressure in areas of higher altitudes due to a less denser air space.
So, this explains the answer.
When a car is slowing down, it has a negative acceleration. Although it is not going a negative speed, it is decreasing in velocity, which is the definition of a negative acceleration.
Hope this helps!
Answer:
30 m
Explanation:
Let's list out the known variables that we are given in this question.
- v₀ = 15 m/s
- v = 0 m/s
- t = 4 s
We are trying to solve for displacement in the x-direction.
Find which constant acceleration equation contains all 4 of these variables.
Plug the known values into the equation and solve for delta x.
The car goes 30 m after the driver begins to brake.
El sol es una bola de gas así como las estrellas:)
Answer:
v = 2.41 m/s
Explanation:
Here net force on the Skater + snowball is zero
so here we can use momentum conservation for skater + snowball
now we have
so the final speed of skater will be 2.41 m/s
