Question

ऑफ टेन डाइमेंशनल फॉर्मूला फॉर वेलोसिटी एंड चार्ज​

Answer 1

Explanation:

The dimensional formula of Velocity is given by,

M0 L1 T-1

Where,

M = Mass

L = Length

T = Time

Derivation

Velocity (V) = Displacement × Time-1 . . . . (1)

The dimensional formula of Displacement and Time is [M0 L1 T0] and [M0 L0 T1] respectively . . . . (2)

On substituting equation (2) in equation (1) we get,

Velocity = Displacement × Time-1

Or, V = [M0 L1 T-1]

Therefore, velocity is dimensionally represented as [M0 L1 T-1].

Answer 2

Explanation:

To dwell tediously and repeatedly upon a single subject or topic, especially in complaint. Likened to playing the same note over and over again on a harp. Mark is always harping on the same string about how little money he makes.
