Which one of the following quantities does not have unit of force per unit area.

If and Rolle's theorem is applicable to f(x) for then  is equal to

Given n is a positive integer for the function , . By Rolle's theorem the value of c is 1/5 then n is equal to

A medium shows relation between i and r as shown. If speed of light in the medium is nc then value of n is

The graph between sine of angle of refraction (sin r) in medium 2 and sine of angle of incidence (sin i) in medium 1 indicates that

For a small angled prism, angle of prism A, the angle of minimum deviation varies with the refractive index of the prism as shown in the graph

A graph is plotted between angle of deviation and angle of incidence (i) for a prism. The nearly correct graph is

For a convex lens, if real image is formed the graph between (u + v) and u or v is as follows

A limit is the value that the output of a function approaches as the input of the function approaches a given value.

The force required to stretch a steel wire of 1 cm²  cross-section to 1.1 times its length would be 

Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if = n, in which case one writes x = .

The graph shows how the magnification m produced by a convex thin lens varies with image distance v. What was the focal length of the used

The graph shows variation of v with change in u for a mirror. Points plotted above the point P on the curve are for values of v

When light is incident on a medium at angle i and refracted into a second medium at an angle r, the graph of sin i vs sin r is as shown in the graph. From this, one can conclude that

We can only apply the L’Hospital’s rule if the direct substitution returns an indeterminate form, that means
