Pressure equals force/area. Force equals 23 Newtons (N) and area of a circle equals 3.14*radius^2. Therefore pressure equals .46N per mm. l

You exert a force of 25N on the head of a thumbtack the head of the thumbtack has a radius of 5mm what is the pressure on your thumb?
25N
What types of force that exert pressure?
athmospheric pressure
Do you need a large force to obtain a large pressure?
No! Pressure is force per unit area: p=f/a. Thus it does not require a large force to produce a large pressure; reducing the area increases the pressure for the same applied force. The thumbtack, for example, can be considered to be a pressure amplifier since a small force applied to the head becomes a very large force at the pointed end of the thumbtack. Not if you have a narrow bore pipe.
Which direction does a vapor material exert a pressure or force?
Vapor materials exert their pressure in just about every direction
Does light have force in it?
Light is a form of energy. Light can exert a pressure.
When you exert force on a fluid in a closed container does the pressure increase decrease or remain constant?
The pressure increases.
If you stand on one foot you increase the pressure you exert on the ground because?
you have decreased the area over which the force is applied, and pressure is force per unit area
Where do the rocket exerts force in pressure?
Rockets exert force at the upper part of the combustion chamber. This pushes the rocket forward.
When you exert a force on an object it exert the?
opposite and equal force against you.
How does a gas exert pressue on the container in which it is being held?
A gas exerts pressure on the container because it is bouncing off the walls of the container at a certain force. The greater the force is the greater the pressure.
Do you exert more force when you are closer to the fulcrum?
do you exert more force when you are further from the fulcrum
How do gas particles exert pressure on their container?
'This is because the air particles are bumpinginto each other and the walls. When this happens it causes pressure on the walls because of the speed the air particles are moving
