## How do you find no solution?

Summary. If the equation ends with a false statement (ex: 0=3) then you know that there’s no solution. If the equation ends with a true statement (ex: 2=2) then you know that there’s infinitely many solutions or all real numbers. Let’s see an example of both of these.

## How do you find I in algebra?

The imaginary unit The second property shows us that the number i is indeed a solution to the equation x 2 = − 1 x^2=-1 x2=−1x, squared, equals, minus, 1.

## What is the working equation?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

## What is S in work formula?

Answers – Work and Energy 1. Work equals the force F times the displacement s times the cosine of the angle F,s between the force F and the displacement s: W = (Fs cos F,s)

## What is the formula for time and work?

Important Time and Work Formula Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.

## What is the formula of power?

Power Formula 2 – Mechanical power equation: Power P = E ⁄ t where power P is in watts, Power P = work / time (W ⁄ t). Energy E is in joules, and time t is in seconds.

ampere

## How do you find power?

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.

## What is the formula of stress?

It is represented as N/m2. Stress formula is made use of to find stress applied on any given body if force and area on which force is exerted is given in the problem….Answer:FORMULAS Related LinksError FormulaHyperbola FormulaChi Square FormulaRsd Formula3

## What is the breaking stress?

The stress applied to a material is the force per unit area applied to the material. The maximum stress a material can stand before it breaks is called the breaking stress or ultimate tensile stress. Tensile means the material is under tension.

## What is unit for stress?

Units. The dimension of stress is that of pressure, and therefore its coordinates are commonly measured in the same units as pressure: namely, pascals (Pa, that is, newtons per square metre) in the International System, or pounds per square inch (psi) in the Imperial system.
