Find the slope and equation of the line tangent to y = \frac{2x\sqrt x - 8x}{\sqrt{x }] at x = 4. Find the equation of the line tangent to y = x^2 - 2x with a slope of 2. Find the slope and an equation of the tangent line t...
What equation will be used to calculate the heat of fusion of ice? The specific heat of water is 4.184J/(g⋅C), and the heat capacity of the calorimeter is 1.0×101J/C. Heat of fusion Heat of fusion is a change in enthalpy due to the contribution of energy (i.e. he...
Calculate the force required to change the velocity of a 150-kg rocket from at rest to 200 m/s in 25 s. How do you set up the equation to find the final velocity of an object sliding down a rough incline if it has an initial...
There is not an equation as you mean it. In the case of your circuit, the non-inverting gain will be about 3.2, so the amplitude of the output will increase without limit - until it hits a limit. In this case,that limit is set by the op amp output stag...

How is the original equation affected by this? Answer: (a) Time effects will pick up the effect of omitted variables that are common to all 50 states at a given point in time. Federal fiscal and monetary variables, exchange rate and U.S. terms of trade movements, aggregate business cycle...
Now a function which has a derivative proportional to itself is an exponential, and the solution of this differential equation is n=n_0e^{−mgh/kT} \tag{40.1} Here the constant of integration, n0, is obviously the density at h=0 (which can be chosen anywhere), and the density goes...
Answer to: What power is taken from the source given: V_o = 15 \space V, R = 1 \space \Omega, \omega L = 4 \space \Omega, \frac{1}{\omega C} = 3...
The same for electric power. Since electric power is given by the equation {eq}P = VI {/eq}, we can transform it to {eq}\displaystyle P = \frac{V^2}{R}\ {/eq}or {eq}P = I^2 R {/eq}. Answer and Explanation: For convenience, we are going...
