YES
A barometric pressure of zero is a vacuum.
Electromagnetic force field.
The space with a pressure of zero pascals is called a vacuum. In a vacuum, there is an absence of gases and atmospheric pressure.
The ultimate objective of a manufactured vacuum is zero pressure.The better the vacuum, the closer the pressure is to zero.
If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.If it is a perfect vacuum, any amount of it will have zero pressure.
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
When an objects net force is zero, its acceleration is zero. No force , no acceleration.
Gravitation can't be cancelled or shielded. You can have the appearance of zero gravitational force when you are in free fall. Without going into outer space, this can be maintained for a few seconds at most.
according to me zero unbalanced force is when force is applied in an object and it is not balance ,if there is no inertia due to it then it is called zero unbalanced force.
Net force is defined as the overall force acting on an object. When a cat sleeps on a table, the net force on it is zero. When a body is at rest the net force acting on the body is zero.
Vacuum is measured in inHg or inches of mercury and a true vacuum is anything below zero on this scale...for reference normal atmospheric pressure or air pressure is about 14.7 inHg so anything less than that could be expressed as a vacuum or less than atmospheric pressure if above zero but less than 14.7 inHg...you can measure this with a vacuum gauge that you can get at any autoparts store but you can feel a vacuum as a suction just like your vacuum cleaner....So a vacuum is anyththing zero inHg or below and a partial vacuum is anything between zero and 14.7 inHg.
No, vacuum does not have a buoyancy force because buoyancy is a result of differences in pressure within a fluid. In a vacuum, there is no fluid to exert pressure so there is no buoyant force.
