What is a quantity usually expressed as a percentage that measures the ratio of a useful work output to work input?
Efficiency is a quantity that measures the ratio of useful work output to work input, usually expressed as a percentage. It helps quantify how well a system or process utilizes energy while minimizing waste.
How much a quantity decreases in comparison to the original?
The decrease in quantity is usually expressed as a percentage of the original quantity. This percentage is calculated by dividing the decrease by the original quantity and multiplying by 100. The result gives the percentage decrease relative to the original quantity.
What is a quantity usually expressed as a percentage the measure the ratio of work output to work Input?
Efficiency is a quantity typically expressed as a percentage to measure the ratio of work output to work input. It indicates how effectively a system or process is utilizing energy or resources to produce desired outputs.
Efficiency is usually expressed as a what?
Efficiency is usually expressed as a ratio of output to input, such as output divided by input. It measures the effectiveness of achieving desired results with minimal waste of resources.
What is the percentage of energy used to do work called?
The term EFFICIENCY is defined as useful work, divided by total energy expenditure.

What does percentage mean?
In mathematics, a percentage is a way of expressing a number as a fraction of 100 (per cent meaning "per hundred". It is often denoted using the percent sign, "%". For example, 45% (read as "forty five percent" is equal to 45 / 100, or 0.45. Percentages are used to express how large one quantity is relative to another quantity. The first quantity usually represents a part of, or a change in, the second quantity. For example, an increase of $ 0.15 on a price of $ 2.50 is an increase by a fraction of 0.15 / 2.50 = 0.06. Expressed as a percentage, this is therefore a 6% increase. Although percentages are usually used to express numbers between zero and one, any dimensionless proportionality can be expressed as a percentage. For instance, 111% is 1.11 and −0.35% is −0.0035.
What is a quantity that measures the rate at which work is done?
Work is usually measured in joules, which are a unit of energy. Work/time is called power and is usually measured in Watts (joules/second) other common units of power include Horsepower and ft*lbs /sec. in short, is is power, which is measures in watts.
What is the percentage of energy used to do work called?
The term EFFICIENCY is defined as useful work, divided by total energy expenditure.
Is the difference between the price of a good and the cost to make the good on a per product basis and it is usually expressed as a percentage?
_____ is the difference between the price of a good and the cost to make the good, on a per product basis; and, it is usually expressed as a percentage.
What does an oxygen meter measure?
An oxygen meter measures the concentration of oxygen in a particular environment, usually expressed as a percentage of oxygen in the air. It is commonly used in medical settings to monitor oxygen levels in blood (pulse oximeter) or in industrial settings to ensure safe oxygen levels for workers.
Efficiency can be express mathematically as?
Efficiency = Output/Input. This is usually expressed as a percentage but may be given in the form of a ratio.Another AnswerEfficiency is output power divided by input power, normally expressed as a percentage.
