Physics
1 answer:
kirill115 [55]3 years ago
3 0

Answer:

Potential energy is the energy that is stored in an object. ... When you park your car at the top of a hill, your car has potential energy because the gravity is pulling your car to move downward; if your car's parking brake fails, your vehicle may roll down the hill because of the force of gravity.

What is an example of a mechanical noise?
faltersainse [42]
Resonance:
The resounding recurrence is the recurrence at which a bit of metal, plastic or whatever else swings/vibrates with minimal measure of vitality input. Think about a man on a play area swing. You realize that it requires next to no push to keep the individual swinging. The recurrence at which they swing forward and backward is their full recurrence. In the event that you endeavor to influence them to swing speedier or slower, it will take altogether more vitality.

Resonating Panels:
This kind of clamor is caused when the bass notes are an indistinguishable recurrence from the thunderous recurrence of a metal or plastic board. To stop or decrease the commotion related with this kind of issue, you can do two or three things.

Rattling:
This sort of commotion would be caused when 2 bits of metal, plastic, whatever... are sufficiently close to hammer into each other when they resound. This is most likely best illuminated by filling the hole between the two vibrating parts with silicone sealant or shut cell froth climate stripping. The climate stripping is a superior arrangement in places like behind the tag. On the off chance that you have a tag outline, you can get some truly thin climate stripping and put between the casing and the plate.

During the expansion of a gas in piston-cylinder the relation between the pressure and the volume is given as
Iteru [2.4K]

Answer: The relationship between the pressure and the volume is given as P=K/V or PV= K. (Pressure increases as Volume decreases).

Explanation:

When gas is trapped in an enclosed medium for example a cylinder by a piston. When the piston is pushed in, the gas particles will have less room to move as the VOLUME the gas occupies has been DECREASED. This will automatically lead to frequent collision of the has particles with the wall of the container. The collision exerts forces which leads to INCREASED PRESSURE.

This obeys the Boyle's law which states that the volume occupied by a fixed mass of gas is inversely proportional to the pressure, provided temperature is kept constant. This can be mathematically expressed below:

PV=K, where K is constant

P1 V1=P2 V2

Where,

P1= initial pressure

V1= initial Volume

P2= final pressure

V2= final Volume.

Therefore, increasing pressure from initial pressure to final pressure means that initial volume will change to final volume, providing the temperature remains constant.
