What else can I help you with?
Why can objects that do not touch still exert a force on one another?
Objects that do not touch can still exert a force on each other through fields such as gravitational, electrical, or magnetic fields. These fields create a force that can act at a distance without physical contact between the objects.
Why does the Bourdon gauge not read zero pascals when no pump is connected and the valve is open?
It is because air can still go into the metal tube, and the atmospheric pressure (14.7 psia) will still force the tube to uncoil a bit. But the reading won't be very high.
Would a sample of gas in a closed container in space exert pressure on the sides of the container if the gas was kept at standard temperature and pressure?
Even if the pressure inside a container is equal to the pressure outside a container, there is still pressure. It's like pushing a friend one way while he pushes you back. Neither of you may be moving, but you're still pushing. The sample of gas would exert exactly one atmosphere of pressure (or 100 kPa) on the container. The question then becomes whether the container can withstand that pressure.
Is there pressure in space?
Yes, there is pressure in space, but it is very low compared to Earth's atmosphere. Space is a vacuum, so there is no air pressure like we experience on Earth. However, there is still some pressure exerted by particles and radiation in space.
What would happen if you are standing on a weighing scale and all of a sudden the atmosphere vanished The reading on the scale would?
The reading on the scale would remain the same. Weight is a measurement of the gravitational force between you and the Earth, not the atmospheric pressure. Without the atmosphere, the force of gravity would still act on you, keeping your weight constant.
Are mafias still a prevalent force in today's society?
Yes, organized crime groups, including mafias, continue to exist in various parts of the world and can still exert influence in certain sectors of society.
When we use a simple machine do we do less work?
Simple machines make work easier by allowing us to apply force over a greater distance, but the amount of work done remains the same. This means that while we may exert less force when using a simple machine, we still need to exert the same amount of work.
Because the sun is so far away it does not exert a gravitational force on the earth?
Actually, the sun's gravitational force is what keeps Earth in orbit around it. The force of gravity decreases with distance, but it still influences objects at a considerable distance like the Earth.
Does water start to boil at 45?
Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level under normal atmospheric pressure. If you are at a higher altitude, the boiling point can be lower due to the decrease in atmospheric pressure, but it will still be above 45 degrees Celsius.
Does the Sun exert a gravitational force on the Moon?
Yes, the Sun exerts a gravitational force on the Moon. This gravitational force contributes to the Moon's orbit around the Earth and influences its motion, causing various phenomena such as tides on Earth.
In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.
Air pressure is really the?
Air pressure is the weight (not the mass) of the total column of air over a specified area at Earth's surface. It usually measured in kilopascal (about 101 kPa) or mm of mercury (760 mm Hg). Old style units still in use in America include pounds force per square inch (14.7 psi)
