Question

Match items of List I with List II and select correct answer from the code below:

List I	List II
1. Time	(a) Pascal
2. Pressure	(b) Joule
3. Electric capacitance	(c) Second
4. Heat	(d) Farad.

1. 1 - a, 2 - b, 3 - c, 4 - d
2. 1 - d, 2 - b, 3 - a, 4 - c
3. 1 - c, 2 - a, 3 - d, 4 - b
4. 1 - c, 2 - a, 3 - b, 4 - d

Answer 1

Correct Answer - Option 3 : 1 - c, 2 - a, 3 - d, 4 - b

CONCEPT:

Physical Quantities and Units

• Units are standard for the measurement of a physical quantity.
• The measurement of the quantity is basically mentioned in two parts, the first part gives how many times the standard unit and the second part gives the name of the unit.
  • For example-   Suppose we say that the time interval for the happening of two events is 10 Seconds. The numeric part 10 says that it is 10 times the unit of time and the second part second says that unit.

EXPLANATION:

• The units given in the question with the correct match are as explained below. 
• Match items of List I with List-II and select the correct answer from the code below:

Physical Quantity	Unit	Definition
1. Time	(c) Second	Use to measure time
2. Pressure	(a) Pascal	Force per unit area
3. Electric capacitance	(d) Farad	.Energy storage capacity in form of charge
4. Heat	(b) Joule	A form of energy that measures hotness or coldness

• So the correct match is 1 - c, 2 - a, 3 - d, 4 - b
