The quantity v/r is called
WebbShould I write "amount of," "quantity of," or "number of"? "Amount of," "quantity of," and "number of" are easy to confuse. "Amount of" is used for singular things you cannot measure. For example: A large amount of disdain. "Quantity of" is used for a singular (and sometimes plural) thing you can measure, particularly if it's inanimate. WebbThe Vander waal's equation for ideal gas is given by (p + V 2 a ) (V − b) = R T where P is pressure, V is volume a and b are constants, R is universal gas constant and T is absolute temperature. Then the dimensions of b a are same as that of:

Webb5 mars 2024 · Force is mass times acceleration, and is therefore a mass times a distance divided by the square of a time. We therefore say that [Force] = MLT −2. The square brackets mean: “The dimensions of the quantity within”. The equations indicate how force depends on mass, length and time. We use the symbols MLT (not in italics) to indicate … Webb3 apr. 2024 · The numerator of the index is simply the total expenditures of all items at the observation period using base period quantities, while the denominator is the total expenditures of all items using base period prices and quantities.

WebbThe term RMS stands for the (square) root of the mean of the squares of instantaneous current values. The RMS value of AC current or voltage can be calculated from the following relation: IRMS = 0.707 x peak value of current. V RMS = 0.707 x peak value of voltage. It is the actual value of an alternating quantity that tells us the energy ... WebbPhysicists often use square brackets around the symbol for a physical quantity to represent the dimensions of that quantity. For example, if r r is the radius of a cylinder and h h is its height, then we write [r]= L [ r] = L and [h] =L [ h] = L to indicate the dimensions of the radius and height are both those of length, or L.
