Answer 1

1) it is used to represent change in some quantity
2). it represent lots of quantities for example in kinematics it is used to represent coefficient of static friction and to represent electric mobility of a charge
3)it is a function to be differentiated it means that the function have to be differentiated with respect to X
4)it is a particular frequency of light and this term is widely used in optical networking ....

Answer 2

Explanation:

i)In general physics, delta-v is a change in velocity. The Greek uppercase letter Δ (delta) is the standard mathematical symbol to represent change in some quantity. ... v0 or v0 is initial velocity (at time t0), v1 or v1 is subsequent velocity (at time t1).

ii)The lowercase Greek letter mu (µ) is used to represent the prefix multiplier 0.000001 (10 -6 or one millionth). ... The symbol µ is sometimes used to represent permeability, an expression of the extent to which a substance concentrates magnetic lines of flux.

iii)dy/dx represents the derivative of y with respect to x. The operator d/dx is operating on y. DeadOriginal said: It should never be treated as a fraction.

iv)Wavelength, distance between corresponding points of two consecutive waves. ... Wavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f.

v)Omega (uppercase/lowercase Ω ω) is the 24th and the last letter of the Greek alphabet. ... In electromagnetism and engineering, the uppercase Ω is used as the symbol for ohms, which are the units of electrical resistance. In physics and other sciences, the lowercase ω is often used to represent angular frequency.
