Question

Tick (✓) the most appropriate answer.
1. With the increase in the weight of an object,
the pressure :
(a) increases
(b) decreases
(c) is not affected (d) none of these
2. With the increase in the area of contact of
an object, the pressure :
(a) increases
(b) decreases
(c) is not affected (d) none of these.
3. One pascal is the pressure generated by:
(a) force of 1 N on 1 m2,
(b) force of 1 kgf on 1 m2,
(c) force of 1 N on 1000 cm2,
(d) force of 1 N on 1 cm2
4. In order to glide on snow, one must wear
(a) spiked shoes
(b) flat rubber shoes
(c) flat and long skies
(d) none of these
5. The rear wheels of tank trailor have large
number of wheels so that :
(a) they can withstand the load of tank
(b) reduce pressure on the road
(c) increase pressure on the road
(d) all of these​

Answer 1

1
(A) increases (because pressure is thrust per unit area)

2
(B) decreases (because pressure is inversely proportional to the area of contact)

3
(A) force of 1N on 1m^2

4
(C) flat and long skies

5
(B) reduce the pressure on the road

Answer 2

Answer:

1.) With the increase in the weight of an object the pressure :- a) increases

2. With the increase in the area of contact of

an object, the pressure : -b) decreases

3. One pascal is the pressure generated by: - a) force of 1 N on 1 m2

4. In order to glide on snow, one must wear :-c) flat and long skies

5. The rear wheels of tank trailor have large

number of wheels so that : -  both option a) and option b) is correct
