Question

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 1

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.

Answer 2

Answer:

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.
