rate of change of quantity

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..

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 constant and t..

If we consider concentrations at t 1 = 0 min and t 2 = 40 min, then the rate of change of concentration of Cisplatin is calculated as follows: Rate of change of concentration of Cisplatin The reaction rate is defined as the rate of decreas..

Fuel is being pumped into a tanker at a rate of 75 gallons per minute. The quantity of fuel in the tanker is a function of the number of minutes the fuel is pumped. Which of the following equations represents the quantity of fuel in the tanker? => A = 75 / n or A= ..

If the rate of change in the area of a circle is 0.8 cm 2 /sec, then find the rate of change in the circumference of the circle when the radius is 4 cm. => 0.4 cm/sec or 50.26 cm/sec or 0.2 cm/sec or 197.39 cm/sec or 3.2 cm/sec..

The rate of change of each side length of an equilateral triangle is 9 cm/s. Find the corresponding rate of change in its area when the side lengths are 8 cm each. => 18 3 cm 2 /s. or 27 cm 2 /s or 16 cm 2 /s or 36 3 cm 2 /s...

The rate of change of each side length of an equilateral triangle is 3 cm/s. Find the corresponding rate of change in its area when the side lengths are 12 cm each. => 18 3 cm 2 /s. or 36 cm 2 /s or 9 3 cm 2 /s. or 9 cm 2 /s..

The radius of a sphere is increasing at the rate of 1 cm per second. Find the rate of change of its volume when the radius is 4 cm. => 64 cm 3 /sec or 64π cm 3 /sec or 64 / 3 cm 3 /sec or 64 / 3 π cm 3 /sec or 16π cm 3 /sec..

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..
