capacitor plates. We can rearrange this equation as iR +q/C = ε (2) The above equation contains two variables‚ q and i‚ which both change as a function of time t. To solve this equation we will substitute for i dq i= dt (3) dq q R + =å (4) dt C This is the differential equation that describes the variation with time of the charge q on the capacitor shown in Fig. 1. This dependence can be found as follows. We will rearrange the equation to have all terms involving q on the left

DEMAND FORECASTING Demand forecasting is the process of predicting future average sales on the basis of historical data samples and market intelligence. The volatility of demand from an average level is supplied from the safety inventory. Any forecast is likely to be wrong‚ so the focus should be on understanding the range of potential forecast errors and the level of safety inventory that will cater for peak demand. An important additional calculation is forecast bias. This is the cumulative

compound interest‚ calculating population growth or decay‚ and carbon dating. Using logs is a key component when solving for compound interest. Whenever you are calculating the interest on an investment that is compounded continuously‚ a natural exponential function is used. To solve for continuously compounded interest you use the formula A(t) = Pert‚ where P is the principal‚ r is the interest rate‚ and t is the number of years since the investment was made. Without the use of logs finding the interest

The Vector equation of a plane To find the vector equation of a plane a point on the plane and two different direction vectors are required. The equation is defined as: where a is the point on the plane and b and c are the vectors. This equation can then be written as: The Cartesian equation of a plane The cartesian equation of the plane is easier to use. The equation is defined as: One of the advantages to writing the equation in cartesian form is that we can easily find the normal

The goal for this experiment is to determine which out of the four balanced chemical equations best represent the thermal decomposition of sodium bicarbonate. The guiding question will be answered with the outcome of the sodium bicarbonates thermal decomposition and it being plugged in into the four balanced chemical equations. John Dalton atomic theory explains two fundamental laws of chemistry which are the law of conservation of mass and the law of definite proportions. The atomic theory states
