## What is the formula for calculating the efficiency of a heat engine Brainly?

Answer: Efficiency = StartFraction T Subscript h Baseline minus T Subscript C Baseline over T Subscript h Baseline EndFraction times 100.

## How do you find efficiency in physics?

Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.

## What is an efficiency?

An efficiency apartment is a small apartment unit that, true to its name, combines the functionality of multiple rooms into one. An efficiency apartment typically combines the bedroom, living room and kitchen all into one single room. Efficiency apartments are often considered the same as studio or bachelor apartments.

## What is line efficiency?

Line efficiency is the ratio of the number of hours during which a high-volume pick-and-place machine actually places parts on the PCB divided by the number of hours during which the SMT assembly lines are staffed (placement time/staffed time x 100). Therefore, reliable data is commonly available for placement time.

## Is rated power input or output?

In electrical engineering and mechanical engineering, the power rating of equipment is the highest power input allowed to flow through particular equipment. According to the particular discipline, the term “power” may refer to electrical or mechanical power.

## What are the 4 energy transfers?

There are 4 ways energy can be transferred;

- Mechanically – By the action of a force.
- Electrically – By an electrical current.
- By radiation – By Light waves or Sound waves.
- By heating – By conduction, convection or radiation.

## What kind of energy do light waves transfer?

electromagnetic radiation
