Within an internal combustion engine, the can-shaped component that moves up and down the cylinder and is the main moving part in the engine is the A. connecting rod.
B. crankshaft.
C. piston.
D. spark plug.

Answers

Answer 1

Answer:

Answer;

C. piston.

Explanation;

A piston is a cylindrical component of the engine that slides back and forth in the cylinder bore by forces produced during the combustion process. It is the can shaped engine component that moves up and down the cylinder and is the main moving part of an engine.
It acts as a movable end of the combustion chamber. Pistons are made of cast aluminium alloy to allow excellent and light weight thermal conductivity. They consists of a piston head, piston pin bore, piston pin, skirt piston rings, ring grooves and ring lands.

Answer 2

Answer: The crankshaft turns that moves the connecting rod up and down and the piston is inside the cylinder up and down movement.Answer piston

gas stored in a tank at 273 k has a pressure of 50kpa. what happens to the volume when the pressure is decrease due to the added pressure

Answers

I can't think of any way that pressure can be decreased due to added pressure.

Be that as it may, and it certainly still is ...

No matter what you do to the pressure or the temperature of
the gas in that tank, the volume doesn't change. Any sample
of gas always expands to fill the container in which it's confined.
Its volume doesn't change until you either transfer it to another
container with different volume, or else change the volume of
the container it's in.

What is the potential of a 35kg child sitting at the top of a slide that is 3.5m above the ground? What is her kinetic energy if she moves down the slide at a speed of 5.0m/s??

Answers

Ep = mgh
= (35)(9.8)(3.5)
= 1200.5 J

Ek = (1/2)(mv^2)
= (0.5)(35)(5^2)
= 437.5 J

a soap film is viewed in white light. if the film is much thinner than the wavelength of blue light, what is the appearance of the film?

Answers

When a soap film is viewed in white light and the film is much thinner than the wavelength of the blue light, the film will seem to be totally transparent. The thin film will reflect no visible light. It actually depends on the thickness of the film through which the light is being transmitted. I hope the answer helps you.

If the force of gravity on an object increases, what happens to its weight?

Answers

Answer:

It also increases

Explanation:

The strength of the gravitational force between two objects depends on two factors, mass, and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
