PLEASE HELP!! Identify at least ten different wheels in your home and/or in your community. At least three should be wheels that are not associated with transportation. For five of them, do the following: Measure the diameter (the distance from one edge to the opposite edge, going through the very center) of each wheel.
Describe each wheel, its size, and its use.
Explain where the force comes from that causes the torque.

A doorknob - about 10cm for diameter and the force that causes the torque comes from the person turning the doorknob causing friction. It’s used to open and close doors.

A screwdriver- 2m for diameter and the force that causes the torque comes from the person applying pressure and causing the screwdriver to turn with friction. It’s used to screw a screw into the wall or into an object.

Car wheels- about 12inches in diameter and the force that causes the torque comes from the engine’s chemical force and friction against the road. They’re used to make a car go and stop.

Electric fan- 14 inches in diameter and the force for torque comes from the electricity circulating from the fan making it spin to provide the air coming out of the fan. They’re used to provide people with air as a cooling system.

Pizza cutter- 10cm in diameter and the force for torque comes from the pressure being applied on the handle and the friction between the pizza and the pizza cutter. They’re used to cut pizza.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
