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.

What is the unit of current *?

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 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.
