Newtons 2nd law equation

What does Newton’s second law equation mean? For a constant mass m, Newton’s second law looks like: F = m * (V1 – V0) / (t1 – t0) The change in velocity divided by the change in time is the definition of the acceleration a. The second law then reduces to the more familiar product […]

Expectation equation

How do you calculate expectation? The basic expected value formula is the probability of an event multiplied by the amount of times the event happens: (P(x) * n). What is expectation function? Using expectation, we can define the moments and other special functions of a random variable. Definition 2 Let X and Y be random […]

Tensile stress equation

What is the formula for tensile stress? Difference Between Tensile Stress And Tensile Strength Tensile stress Tensile strength The formula is: σ = F/A Where, σ is the tensile stress F is the force acting A is the area The formula is: s = P/a Where, s is the tensile strength P is the force […]

Quotient rule equation

What is the formula for Quotient? The answer after we divide one number by another. dividend ÷ divisor = quotient. Example: in 12 ÷ 3 = 4, 4 is the quotient. What is quotient rule in math? The quotient rule is a formal rule for differentiating problems where one function is divided by another. It […]

Equation for decibels

How do you calculate dB? Find the logarithm of the power ratio. log (100) = log (102) = 2 Multiply this result by 10 to find the number of decibels. decibels = 10 × 2 = 20 dB If we put all these steps together into a single equation, we once again have the definition […]
