Hi.

Indicate which of the following physics symbols denote units and which denote variables or quantities.

a. C

b. c (cursive)

c. C (cursive)

d. t (cursive)

e. T

f. T (cursive)

Answer: Units: C, T and Variables: c, C, t, T

(a) C is the unit of charge Coulomb, (e) T is the unit of magnetic field strength Tesla.

In physics, units are written straight and variables are written in italics. Various italic symbols are used for various quantities like t for time, T for temperature, c for any constant and C for curie constant.

Options a and e are units which are C and T.

While options b, c, d and f are variables or quantities.

Explanation:

The units are the signs or representation of a standard amount of an physical quantity like meter for length.

Here C and T are units because they are not in cursive form.

C is unit of charge Coulomb while T is Tesla the unit of magnetic field strength.

Variables are written in italics or cursive form. As:

c = any constant. C = curie constant. T = Temperature. t = Time.
