The upthrust force needed to float on water is equal to the weight of the person (or raft) and any additional load they are carrying. As long as the upthrust force is greater than or equal to the total weight of the person and the raft, they will float on the water.

What is the smallest upthrust force needed so that and object weighing 1600 N will float?

The smallest upthrust force needed for an object to float is equal to its weight. So, for an object weighing 1600 N to float, the upthrust force needs to be at least 1600 N. This is because the upthrust force is equal to the weight of the fluid displaced by the object, which in this case is equivalent to the weight of the object.

What is the minimum upthrust force needed to make 1600 newtons float?

The minimum upthrust force needed to make an object float is equal to the weight of the object. In this case, the minimum upthrust force needed to make an object weighing 1600 newtons float is also 1600 newtons.


If a boy weighed 500 n what upthrust would he need to float?

He would need an upthrust force equal to his weight of 500 N in order to float. Upthrust is the force exerted by a fluid (like water) that opposes the weight of an object placed in it. When the upthrust force is equal to the weight of the object, the object will float.


What is the upward force making things float?

upthrust


What is the meaning of upthrust force?

Upthrust force, also known as buoyant force, is the force exerted by a fluid on an object immersed in it, pushing the object upward. It is equal to the weight of the fluid that the object displaces. Upthrust force is what allows objects to float in a fluid.


Will a submarine sink or float when it's weight is equal to the upthrust acting on it?

If the weight of the submarine is equal to the upthrust acting on it, the submarine will float. This is due to Archimedes' principle, which states that an object will float when the buoyant force acting on it is equal to the gravitational force pulling it down.


How do balls float?

Well balls float-cos the force of upthrust from the water is pushing them up-and is stronger than gravity.The surface area increases the upthrust-which is why pumped balls float better than deflated.


What does upthrust maen?

Upthrust, also known as buoyant force, is the upward force exerted by a fluid (such as water or air) on an object immersed in it. This force is equal to the weight of the fluid displaced by the object and helps objects float in a fluid.


Whats the definition for upthrust?

The definition for: Upthrust is a force that helps something float. An object that is partly, or completely, submerged experiences a greater pressure on its bottom surface than on its top surface.


What is upthrust force in physics?

Upthrust force, also known as buoyant force, is the force exerted by a fluid on an object immersed in it. It acts in the opposite direction of gravity and is equal to the weight of the fluid displaced by the object. Upthrust force is what allows objects to float in a fluid.


What are the different types of upthrust?

Positive upthrust: when the buoyant force acting on an object is greater than its weight, causing it to float. Neutral upthrust: when the buoyant force is equal to the weight of the object, causing it to remain suspended in a fluid. Negative upthrust: when the buoyant force is less than the weight of the object, causing it to sink.
