rate of change of quantity of displacement with time?

Rate of Change of Quantity - If a quantity y varies with respect to another quantity 'x' satisfying some rule y = f(x), in other words if y is a function x, then represents the rate of change of y with respect to x For x = x 0 , ..

If a quantity y varies with respect to another quantity 'x' satisfying some rule y = f(x), in other words if y is a function x, then represents the rate of change of y with respect to x For x = x 0 , dy/dx at x 0 is called the rate of change..

Suppose a bus starting from a terminus A travels 15000 m to reach terminus B. Then the distance covered by the bus is 15000 m. Now if the bus returns to the terminus A, then what is the distance covered by the bus during the return trip? The distance covered is 15000 m. But the total distance cover..

Rate of a Reaction - Rate of reaction basically means the speed at which a chemical reaction occurs. The speed of a reaction is determined by monitoring the concentrations of the reactants or products at intervals of time. The volume of the reaction vessel is kept cons..

B shows that one mole of A produces one mole of B and thus the rate at which the concentration of A decreases will be the same as the rate at which the concentration of B increases. The decrease or increase in the concentration of the reactants or products may also be expressed ..

Types of Environmental Changes - Environment of earth includes the whole of atmosphere, hydrosphere as related to biosphere. Therefore, environment includes nature, composition of air, characters of hydrological parameters, sunshine, air pressure, temperature, water resources - their stor..

Summary - In a physical change the shape, size, appearance or state of a substance may alter, but it is a temporary change, which is usually reversible. There is no new substance formed, no change in the mass of the substance and no energy changes are involve..

The spontaneous breaking up of the nucleus is known as radioactive disintegration or radioactive decay. Radioactive disintegration is found to obey the following two laws: i) Atoms of all radioactive elements are undergoing spontaneous disintegration i.e., are constantly breaking to form fresh radi..

The amounts of reactants and products in a chemical reaction are related by stoichiometry. Therefore, the concentration of any reactant or product can be used to express the rate of a reaction. Take for e.g., in the reaction A + B C for every molecule of A consumed, a molecule of B is als..

The displacement of a body with time t is related as S = a e 6t - b e -4 t . Find the rate of change of displacement with respect to time t . => 6 ae 6 t + 4 be - 4 t or ae 6t - be -4 t or ae 6t + be ..
