A body is just floating in a liquid. if the body is pressed down and and released what will happen?
If a body is floating IN a liquid, it has neutral buoyancy- does not go up or down. If it is floating ON a liquid, it has positive buoyancy. Neutral- when pressed down, body moves down- and when released, it stays there. Positive buoyancy- moves down, when released returns to it's position on top of the liquid.
When does an object have positive buoyancy?
A body has positive buoyancy when its density is lower than the density of the fluid the body is in.
Do positive and neutral attract each other?
both positive and negative objects attract to neutral object so yes positive and neutral will attract each other.
What kind of charged particles does an atom contain?
The nucleus of an atom contains the neutral neutrons and the positive protons. Negatively charged electrons orbit the nucleus.
Where is a positive located in a atom?
in its neutral state atoms are positive the protons in the nucleus are positive
How do you know if you have positive or neutral buoyancy?
If you float well the buoyancy is positive (your mass is less than the mass of the displaced liquid (water?), if you just manage to float or at least don't sink at any great speed, the buoyancy is neutral (your mass equals the mass of the liquid displaced).
What are the types of buoyancy?
There are only three types of buoyancy. Positive, Neutral and Negative. Positive rises, neutral is in between meaning its in the center and negative sinks. Your welcome
What are three types of buoyancy?
Positive (Rises) , neutral (Level) and negative (Sinks) buoyancy .
What is neutral positive and negative buoyancy?

What kind of buoyancy do submarines have when they are resting on the surfce of the ocean?
Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.

What has neutral buoyancy?
a submarine
What is neutral buoyancy and how might it be a survival mechanism?
Neutral buoyancy is the ability to float under water. This allows the animal to save energy.
When does an object have positive buoyancy?
A body has positive buoyancy when its density is lower than the density of the fluid the body is in.
What are positive negative and neutral buoyancies?
Positive buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is upward, so the object tries to rise.Negative buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is downward, so the object tries to sink.Neutral buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is zero. The object stays at whatever depthit is released, without rising or sinking.
