How do water, wind, and thermal energy from the sun move about the earth's surface?
Answers
Molecules move more quickly because the sun's light energy transforms into heat energy on the planet. While cooler polar air and water travel away from the poles and towards the equator, warm air and water molecules rise and move in the opposite direction.
What is light energy ?The capacity to make different forms of light visible to human sight makes light energy a sort of kinetic energy. Light is referred to as an electromagnetic radiation that is produced by hot things like the sun, lasers, and lightbulbs. Photons, which are tiny energy packets, are present in light.
Water temperature, biological activities and plant photosynthesis and development are all impacted by light energy.
The air is heated by the sun, and warm air rises. The colder air from the surroundings is forced to enter to replace the rising heated air. The result of this is the wind. Ocean currents function similarly.
Thus, Molecules move more quickly because the sun's light energy transforms into heat energy on the planet.

A pitcher throws a softball toward home plate. When the ball hits the catcher’s mitt, its horizontal velocity is 32 meters/second. The softball’s velocity goes to 0 meters/second in 0.8 seconds when caught. If the softball has a mass of 0.2 kilograms, what’s the force of the impact? Use F = ma, where .
Answers
Answer:
To calculate the force of impact F, first lets calculate the acceleration a of the ball:
a=v/t where v is the velocity of the ball and t is time
a=32/0.8=40 m/s²
To get the force F we need the Newtons second law:
F=m*a where m is the mass of the ball and a is the acceleration.
F=m*a= 0.2*40 = 8 N
So the impact force is F= 8 N.

B. An ice cube melts on the floor, then it evaporates.
C. Bromine is a reddish brown, liquid element. In a closed container, a reddish brown gas exists above the surface of the bromine.
D. Dry ice changes directly to carbon dioxide gas

Sublimation is the process by which solids are instantly transformed into gases. The forces of attraction between solids are completely defeated when they absorb enough energy. Solids, such as dry ice, undergo sublimation.
What is sublimation?Similar to melting, freezing, and evaporation, sublimation is a form of phase transition, or change in a state of matter. Without ever entering a liquid phase, a substance transforms from a solid to a gas through sublimation. Typical sublimation examples include dry ice, which is solid CO2,additional elements that cannot be sublimated. A solid-solid combination is separated by sublimation when one of the components sublimes (transforms from solid to gaseous state without producing liquid) following heating, leaving the other non- sublimable components behind.Sublimation is the direct transition of a substance from the solid phase to the gas phase without passing through the liquid phase in between. Sublimation is an endothermic phase transition that occurs at temperatures and pressures lower than a chemical's triple point in the phase diagram.To learn more about Sublimation refer to:
