Want this question answered?
Nope. it occurs in other liquids and even things. like in the air. for example, when you throw a pen in the air, you will find things like... when you throw a pen, there is a push from the muscle and the gravity. The push from the muscle is greater in this occation so the pen goes up. And when it falls, there is nomore of the push from the muscle and there is an upthrust and gravity. (this is where upthrust works) the force of gravity is greater so it falls. Also, it is because of the upthrust that we are standing on the earth. There's an upthrust acting on us as well as the gravity. But ofcourse, as the gravity is stronger, we do not float up to the sky. but if there wasn't any upthrust, we would be sinking into the earth by now! Also upthrust acts on other liquids like oil and salt water.... whoa.. i wrote alot... hope it helped you!
When a pen is hanging, two forces act on it - the upthrust and the force of tension in the string.
Nothing will happen if you lose a Nintendo pen because there is a second pen in the box
Pen Pen TriIcelon happened in 1998.
Upthrust, I don't understand what you mean...
Upthrust is a Contact Force. :)
upthrust is a scalar or vector
upthrust means the force that keeps the force up
it provides 30 upthrust .
Upthrust is a contact force :)
hap-pen :)
Upthrust cancels weight out, weight is there but you do not feel it.
