Question 1

Which of the following corresponds to a specific quantity?

Accepted Answer

Length

Answer

A 'specific quantity' refers to a measurable physical property that has a definite unit. Length is a fundamental physical quantity, measured in units like meters, and is a direct, specific measurement. Money is an economic concept, and polarity is a characteristic (e.g., positive/negative) rather than a scalar quantity with magnitude and unit in the same way as length or pressure. While pressure is also a specific quantity, length is a more fundamental and universally understood example.

Question 2

The fundamental measure of light intensity is

Accepted Answer

Candela

Answer

Candela (cd) is the SI base unit of luminous intensity. It quantifies the power emitted by a light source in a particular direction, per unit solid angle, weighted by the luminosity function. This makes it the fundamental measure for how bright a light source appears to the human eye.

Question 3

Which of the following relationships is correct?

Accepted Answer

Tera>Giga>Mega

Answer

These are standard SI prefixes used to denote multiples of units. Tera (T) represents 10^12, Giga (G) represents 10^9, and Mega (M) represents 10^6. Therefore, Tera is larger than Giga, and Giga is larger than Mega, establishing the correct descending order of magnitude.

Question 4

The charge is

Accepted Answer

Bipolar

Answer

Electric charge exists in two fundamental forms: positive and negative. Objects can either have an excess of positive charge (protons) or negative charge (electrons). This dual nature, having two distinct poles or types, is why charge is described as bipolar.

Question 5

The symbol used to indicate Unbiased sources

Accepted Answer

Circle

Answer

In circuit diagrams, independent (unbiased) voltage and current sources are typically represented by a circle. A circle with a plus and minus sign indicates an independent voltage source, while a circle with an arrow indicates an independent current source. This convention distinguishes them from dependent sources, which are usually represented by diamonds.
