Answer:
31.42383 m/s
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
= Coefficient of kinetic friction = 0.48
s = Displacement = 0.935 m
= Mass of bean bag = 0.354 kg
= Mass of empty crate = 3.77 kg
= Speed of the bean bag
= Speed of the crate
Acceleration


From equation of motion

In this system the momentum is conserved

The speed of the bean bag is 31.42383 m/s

Answer:Increases
Explanation:
As the temperature increases average kinetic energy of particle is increases.
As the temperature increases molecules started to vibrate at higher frequency which causes to rise in temperature. Mathematically, average kinetic energy is given by

where k=boltzmann constant
T=temperature
Solids, liquids and gases :
In solids the particles like molecules of the substance - are very close to each other. They cannot move far from their positions. In liquids they are separated by some more distance. SO molecules are freely moving inside liquid. But in gases the molecules are free to move with in the volume.
Gaseous molecules have higher speeds.
Solids have good conductivity of electricity. Some liquids are also conductive. gases may be less conductive.
Gases have no shape of their own. Liquids do not have a shape too. Solids can have some shape and retain their shape.
Gases and Liquids flow. Solids do not flow.
Many gases may be invisible or may be faint in color. Visibility of liquids and solids is high.
Gases may not taste. they may smell. Solids and liquids may taste and may or may not smell.
Solids may be transparent to light or may be opaque. Gases may be highly transparent to light.
Sound travels in solids faster than in gases.
