Question 1
1 / -0

Which of the following is not an example of air exerting pressure ?

A
Pressing the brakes of a bicycle.

B
Filling up the bicycle tube with air

C
Riding bicycle against the flow of wind

D
Playing with the kite

Solution

Brakes on a bicycle work using friction (the rubbing force between two things that slide past one another while they're touching). Hence brakes doesn't work on the principle of air exerting pressure.
Question 2
1 / -0

Which of the following cannot be considered as a safety measure taken in times of cyclone ?

A
Storing water for emergencies.

B
Following as instructed over radio

C
Get outside and move around

D
Stay away from stray wire.

Solution

During cyclones it is advised to:
Stay inside and shelter {well clear of windows) in the strongest part of the building, i.e. cellar, internal hallway or bathroom.
Question 3
1 / -0

As an individual caught in a cyclone-prone area, which of the following you must not do?

A
Drink safe and potable drinking water only.

B
Pressurize the rescue force and make undue demands.

C
Step outside only when required.

D
Cooperate with neighbors.

Solution

We have to co-operate and not pressurize the rescue force by making undue demands.
Question 4
1 / -0

Why does a paper slip, held between thumb and finger, get lifted up when we blow air over the paper?

A
Air lifts the paper up.

B
Disturbance produced in the air

C
Blowing over the paper reduces the air pressure above the strip.

D
None of these

Solution

The still air below the paper had greater pressure than the moving air above the paper resulting in paper getting pushed up.
Question 5
1 / -0

What affects the direction of kite in the sky ?

A
Motion of bird in the sky

B
Clouds in the sky

C
Wind blowing in the sky

D
Other kites around it

Solution

A kite relies on tension from the string and moving air across the kits. Kite in the sky creat pressure difference between upper and lower part this pressure difference generate lift force in the kite and keep it flying.
Option C
Question 6
1 / -0

Which of the following states of India is most likely to be hit by a cyclone?

A
Madhya Pradesh

B
Andhra Pradesh

C
Punjab

D
Jammu and Kashmir

Solution

The correct answer is option(B).

A cyclone is a large-scale system of winds that spiral in toward a region of low atmospheric pressure. Cyclones are centred on areas of low atmospheric pressure, usually over warm ocean waters near the equator. The warm moist air over the ocean rises from the surface in the upward direction, resulting in the formation of the low-pressure zone over the surface.This leads to formation of cyclone.

As Andhra Pradesh is nearest to the sea coast line among all the above mentioned states so there are more chances of this state being hit by a cyclone.
Question 7
1 / -0

The eye of a cyclone is:

A
A violent area

B
A calm area

C
A haunted area

D
None of the above

Solution

The eye of a cyclone is a calm area because above the eye, the sky is clear, winds are relatively light, and the strong surface winds that converge towards the center never reach it.
Question 8
1 / -0

Fill in the blanks.
Air moves from a region of _______ pressure to a region of ________ pressure.

A
high, low

B
low, high

C
high, high

D
low, low

Solution

As we know air moves from the region where the air pressure is high to the region where the pressure is low.
Question 9
1 / -0

The diameter of the eye of the cyclone is about

A
$$30-60km$$

B
$70-90km$$

C
$$100-120km$$

D
$$170-200km$$

Solution

Eye of a cyclone ranges in size from $$8 \ km \ (5 \ mi)$$ to over $$200 \ km \ (120 \ mi)$$ across, but most are approximately $$30-60 \ km$$ $$(20-40 \ mi)$$ in diameter.
Question 10
1 / -0

The calm area, which is the center of cyclone, is called as

A
Eye of Cyclone

B
Heart of Cyclone

C
Ear of Cyclone

D
Mouth of Cyclone

Solution

The eye is a region of mostly calm weather (with no rain and very light winds) at the center of strong tropical cyclones.
