Which of the following is not expressed in the power unit: (a) Energy = kg x m/s (b) Pressure = N/m^2 (c) Density = kg x m^-3 (d) Stress/ Strain =N/m^2 (e) Surface tension = N/m Show that the coefficient of surface tension T is given by T = rhPg/2 where P, h...
What is the formula for mass and weight? The formula for weight states that weight is equal to mass multiplied by the acceleration of gravity (i.e., W=MG). The formula for mass can therefore be M=W/G. However, mass is also equal to the net force needed to accelerate an object, ...
what is the formula for matches?? well, let's say you burn a match and before you start burning, you need a source of energy to lit it up. That could be friction when you rub the matchstick against the box. Once it started to lit up, you still need a source of energy for it ...

Now, the second derivative of $\arctan $ can be directly calculated by the Quotient Rule formula. The formula of the Quotient Rule is give as, $f'\left( x \right)=\dfrac{g'\left( x \right)h\left( x \right)-h'\left( x \right)g\left( x \right)}{{{\left| h\left( x...
The formula for the energy of motion is: \(KE=0.5\times m\times v^2\) where KE is kinetic energy in joules, m is mass in kilograms and v is velocity in meters per second. Force and Work Newton's three laws of motion form the basis for classical physics. The first law defines for...
