Decreases, stays the same, increases.
The volume decreases because as air is cooled, the individual molecules collectively possess less kinetic energy and the distances between them decrease, thus leading to a decrease in the volume they occupy at a certain pressure (please note that my answer only holds under constant pressure; air, as a gas, doesn't actually have a definite volume).
The mass stays the same because physical processes do not create or destroy matter. The law of conservation of mass is obeyed. You're only cooling the air, not adding more air molecules.
The density decreases because as the volume decreases and mass stays the same, you have the same mass occupying a smaller volume. Density is mass divided by volume, so as mass is held constant and volume decreases, density increases.
Answer:
Explanation:
The polarization characteristics depend on the shape, size, and optical properties of the surface particles. Generally, the radiation is linearly polarized and is said to be negatively polarized if it lies in the scattering plane and positively polarized if it is perpendicular to the scattering plane.
The correct answer is C. Explains how and why nature does what it does.
Scientific laws have been tested and proven constant in nature. They serve as an explanation for the way nature functions. An example would be the laws of motion, friction, or gravity. These rules of existence will never change and set a foundation for the building of scientific theories and experimentation.
I hope this helps! :)
Because the air gets stuck in the curves of the frissbee
Answer:
2.79 m
Explanation:
Use the static equilibrium condition, net torque actin on the system is zero.
solve for the distance of the person from the wall x
now putting the values we get
= 2.79 m
