Will a submarine sink or float when its weight is greater than the upthrust acting on it?
When the weight of any object surrounded by fluid is greater than the buoyant force on it, it sinks. (The buoyant force is just the weight of the fluid that would be in that space if the submerged object were not there.)
What objects will float sink then float?
A submarine
Why does a submarine can sink and float in water?
because the submarine has the water tank.when the tank is filled then submarine sink in the water.and when the tank is empty then submarine float in water.
How does a submarine relate to astronomy?
the ability of the submarine to float
When a submarine pumps water out of its floatation tank its density decreases and it floats. Why does its density decrease?
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
How does a submarine change its buoynacy so it can float or sink?
This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will.
What makes poo sink or float?
Buoyancy, which is an upward acting force exerted by a fluid , that opposes an object's weight.
Does objects in space float?
When using the most popular definition of the word float, yes, they do. Outside of the influence of gravity, objects that have no force acting upon them and no speed will simply hang in place.
Does a submarine sink or float?
both. they are able to control it
If the upthrust is greater than the weight what happens to the submarine?
Well, if the Upthrust were greater than the weight, there would be a net force upwards, and as a consequence of newtons second law a=F/m it accelerates upwards. Hence, the submarine floats.
How do you make a plastic bottle submarine float then sink and float?
put water in to let it sink... then put air into it to let it float...
What is the different between force and pressure and how will one notice that this is pressure or force?
Force as we all know from elementary education is just a push or a pull... You may say that seawater above an operating submarine is exerting millions of Newton of Force (Newton is unit for force) to the submarine below it.. Now its not easy to imagine or visualize how dangerous that force is taking into consideration the size of the submarine itself... However instead of talking about the total force acting on the whole submarine, we go a little simpler and talk about something we can visualize.. We then say that in every square inch on the surface of the submarine, there is this amount of force that the above seawater exerts- that's Pressure.. Pressure is just Force, but it is a Force described with respect to the surface area it is being exerted... 10 N is a Force. But 10 N pushing a 1 sq cm wall equals a pressure of 10N/sq cm
