1.
Pressure at a point is defined as the:
force acting on a surface
average force acting perpendicularly on a unit area around the point
weight of the body
force × area
2.
Standard atmospheric pressure in pascals is about:
1.013 × 103
1.013 × 104
1.013 × 105
1.013 × 106
3.
When the gas pressure is greater than atmospheric pressure, the manometer relation is:
P = Pa − ρgh
P = Pa + ρgh
P = ρgh
P = Pa
4.
A car tyre inflated to a very low pressure causes:
a smaller contact area and less friction
a larger contact area, more friction and heat
no change
a higher speed
5.
The mechanical advantage of a hydraulic press is:
a/A
A/a
A + a
A − a
