How does density and upthrust compare in size?
Upthrust cancels weight out, weight is there but you do not feel it.
Is upthrust a contact or non-contact force?
Of course, a contact course because the air pushes it up only by milometres but that doesnt mean its not contactical upthrust from your good member Paul Jennings
What are factors affecting upthrust?
upthrust=buoyant force=weight of the body immersed in d liquid so gravity and mass is a cause of upthrust as weight of a body=mass* gravity
What is upthurst?
This is the name given to a bouyancey force. When an object diplaces a fluid, the amount of upthrust received is proportional to the volume of fluid displaced. When an object is floating then the upthrust is equal to the objects weight. When more people get on to a boat, the boat sinks further into the water, displacing more water so that the upthrust increases to balance the new weight. If an object sinks then the amount of upthrust it receives is less than the weight so the object falls. Just because it sinks doesn't mean that there is no upthrust, there is. This is why heavy objects appear lighter if you place them in water.
What happens to the body when the upthrust is less than the weight of the object'?
An object that is COMPLETELY submerged in water has its Upthrust equal its weight, but it doesn't necessarily float, an object could be at the rock-bottom of the ocean, and it would still have its upthrust equal to its weight. This is because the upthrust is equal to the weight of the fluid displaced, and so while the objects volume remains constant, and assuming the density of the fluid it displaces is constant.. The upthrust remains constant, this is unless the object compresses and has its density altered.. I know I didn't directly answer your question, but I hope this helps.. Even if a little.
How does a hot-air balloon rise?
The upthrust on the balloon is greater than the weight of the balloon. Thus, it rises upwards. The upthrust on the balloon is greater than the weight of the balloon because the air inside it has a lower density than the surrounding air.
What two forces act on the hot air balloon?
upthrust and gravity
What force makes a hot air balloon rise up into the air?
The upthrust exerted by surrounding air on the balloon.
What objects use upthrust?
many things use upthrust, some i can name are: a hot-air-balloon, a aeroplane a parachute and possibly a elevator.
Can upthrust be greater than weight?
YES...and examples are flying objects! Interestingly,Any liquid or gas produces upthrust. For example, the upthrust of air keeps a hot air balloon up.
Does resistance affect boats?
UPTHRUST
Why does a air balloon not rise?
To lift the baloon, upthrust should be greater than weight. Mg
Why hot air balloons rises up in the sky?
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
Does gravity not affect on nitrogen balloon?
It does affect a nitrogen balloon.
Give 5 examples of upthrust?
1) A boat on water - upthrust going up keeping it a float also known as buoyancy. 2)Swimmer- upthrust (or buoyancy again) keeps the swimmer on top of the water. 3) A helium filled balloon - helium is lighter than air so it displaces it, pushing up into the air. 4)A hot air balloon - same principals of a helium balloon. can only think of 4 sorry. 5) jumping out of a plane. 6)it is what makes a parachute lift one up when falling.
Does the amount baking soda affect the balloon?
how does baking soda affect the hiegt of the balloon
What is the hypothesis for a rocket balloon?
The hypothesis for a balloon rocket is whether the shape of the balloon will affect the distance that it will travel.
