Assertion (A): Sea divers wear a special suit when they go deep in the sea.
Reason(R): The pressure increases as we go deeper into a liquid.
a) Both A and R are true, and R is the correct explanation of the assertion.
b) Both A and R are true, but R is not the correct explanation of the assertion.
c) A is true, but R is false.
d) A is false, but R is true
Let's say that the box in the picture will move. And it will move in the right direction. This is happening because-
Both the men are pushing it towards right.
Both the push and pull are in the opposite direction.
Both the push and pull are in the same direction.
Which sentence is the MOST RIGHT fit for this image?
Flat shoes are better than heels.
Pressure distribution is less for flat shoes.
In muddy area, it's not a good idea to wear heels.
Less the area, less is the pressure. So heels create less pressure.
Observe the image carefully. What's NOT happening here?
People on the left side win the game.
Nobody wins.
This is balanced situation.
Resultant Force is zero.
Students roll toy cars down the same ramp with different coverings like carpet, foil, and sandpaper. What are they trying to test?
How does the height of a ramp affect the distance a car will roll?
How does the mass of the car affect the distance a car will roll?
How does the surface of a ramp affect how fast a car will travel?
How does the surface of a ramp affect the distance a car will roll?
How do you Calculate Pressure
Force(N)/Area(m2)
Force(kg)/Area(mi2)
Area(m2)/Force(N)
Watch the tyres of tractor rolling. Rear tyres are broader because
It looks good.
Broader tyres lessen the muscular Force required.
Broader tyres lessen the pressure on ground.
Broader tyres lessen the friction on ground.
Pressure can be exerted by solids, liquids and gases.
TRUE
FALSE
This is an example of the everyday application of pressure in:
Solids
Liquids
Gases
Plasma
The pressure inside the syringe will decrease if we move the plunger in:
Direction A
Direction B
We don't have to move the plunger as the pressure will change on its own.
None of the above answers.
The reason gases can be compressed is because:
The particles are very close together.
The particles are merely vibrating.
The particles are unable to move.
The particles are very far apart.
