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.
What is pressure?
The amount of force exerted on a surface
The surface area of an object
The weight of an object
An object will float on water if it is
less dense than water.
more dense than water.
the same density as water.
1 Pa = 1N/m2
When you increase your depth under water, the water pressure on your body
increases
decreases
stays the same
How do you Calculate Pressure
Force(N)/Area(m2)
Force(kg)/Area(mi2)
Area(m2)/Force(N)
Why won't you sink in mud if you wear boots?
Because the surface area is larger creating less pressure.
Has air in it to keep you floating.
Because the mud won't want you.

Watch the green man. Which force(s) are acting in this situation?
Frictional Force only.
Gravitational Force only.
Muscular Force only.
Muscular and Gravitational Force.
At higher altitudes, which one becomes true?
Higher the altitude, higher the atmospheric pressure.
Higher the altitude, greater the force exerted by air molecules.
It's an example of fluid pressure.
The higher you go, lesser is the atmospheric pressure.
