Exercise

A. Darken the circle for correct option in OMR Sheet:

1. SI unit of pressure is:

   • b. pascal
   • The SI unit of pressure is the Pascal (Pa), which is equivalent to Newtons per square meter ($\text{N/m}^2$).

2. The weight of an object is due to the ________.

   • a. gravitational pull of earth
   • Weight is the force exerted on an object due to gravity.

3. The pressure is equal to:

   • b. force / area
   • Pressure is defined as force applied perpendicular to a surface divided by the area over which the force is distributed.

4. The pressure ________ with an increase in area of contact.

   • a. decreases
   • Since pressure is force divided by area ($\text{P} = \text{F/A}$), an increase in area (A) for a constant force (F) will result in a decrease in pressure (P).

5. Atmospheric pressure is maximum:

   • d. at sea level
   • Atmospheric pressure decreases as altitude increases, so it is highest at the lowest altitudes, such as sea level.

B. Fill in the blanks:

1. The pressure of liquid column increases with the depth of the column.
2. The standard unit of pressure is Pascal.
3. Pressure is defined as the force acting on the unit area of the surface.
4. The atmospheric pressure acting on our body from outside is balanced by the blood pressure acting from inside.
5. Barometer is used to measure atmospheric pressure.
6. Liquid pressure is measured by manometer.
