second differential equations

The second and third periods are known as short periods. Each consists of eight elements. The second period starts with lithium (Z = 3) and ends with inert gas neon (Z = 10). The third period starts with sodium (Z = 11) and ends with argon (Z = 18..

The time of a pendulum′s swing varies directly with the square root of its length. If the pendulum is 1 ft long when the time is 0.2 second, find the time if the length is 9 ft. => 0.6 second or 1.8 seconds or 15 seconds or 0.8 seconds..

Differentiation is the process by which the unspecialised embryonic cells change in structure and function during development and growth of an organism to form specialised cell types, tissues, and organs, distinct from one another. Differentiation makes cells of the same g..

The derivative, measures the rate at which the dependent variable changes with respect to the independent variable. It is one of the most important ideas in Calculus. The differentiation of functions are widely used in science , economics, medicine and computer scienc..

We have already defined the derivative of a function f(x) at a particular point 'a' and derivative of f(x) in general for the variable x as f'(a) and f'(x) respectively. The restriction in both the cases is that 'the limit must exist'. If does not exist, then we say that the function ..

The number of grams of salt P( t ) dissolved in water after t seconds satisfies the differential equation d P d t = (0.8)P - (0.004)P 2 . What is the amount of salt dissolved after 20 seconds if the initial amount is 50 gm? => 240 gm or 200 gm or 30..
