Yes, air resistance does slow the paper down. This is because the paper is a wide object, with a lot of surface area. The larger the surface area, the more air resistance will affect the object.
Answer: New absolute pressure is
Explanation:
Gay-Lussac's Law:
This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles. As the gas is enclosed in a rigid metal container the volume of the gas is fixed.
(At constant volume and number of moles)
Given:
Answer:
His speed was 2 m/s, and his velocity was 0
Explanation:
In physics, speed of an object is defined as the change in position with the change in its time. While velocity may be defined as the change in the position of the body with respect to the time taken.
Speed in a scalar quantity which means it has only magnitude while velocity has both magnitude and direction.
To determine change in velocity both direction as well as magnitude has to be changed.
In the context, Kai was 200 m of the library in the north direction. Now for the round trip to the library and back to his position, Kai took 200 seconds time to cover the distance.
So for the round trip, the speed of Kai would be 2 m/s abut the velocity of Kai is 0 as the displacement of Kai is 0.
