What is the smallest upthrust force needed to float 600 Newtons?
your weight
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.
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.
If a boy has a body weight of 500 N what upthrust does he need to float?
Same as his weight
If the weight of an object was 500 newtons and the buoyant force was 75 newtons would the object sink or float?
Sink ...
Does everything has less mass on the moon?
Your mass (kilograms) would stay the same as it never changes. But if you are talking about weight (newtons) it would depend on what you were comparing it to. If you have a weight of 300 newtons on earth then you would weigh 49.8 newtons on the moon therefore you would have lost weight. Whereas if you weighed 20.1 Newtons on Pluto you would weigh 49.8 newtons on the moon, loosing weight.
If an astronaut went to the moon weighed 50 kg how much would he weigh in pounds?
490 newtons (110.2 pounds)
What would you get if you weighed the earth?
Depends where you weigh it. This is really pedantic but weight is a force acting on an object due to gravity, not an inherent characteristic of the object. The Earth has a mass of 6.0x1024 kg. If you weighed it on the Earth (?) it would weigh 6.0x1025 Newtons but on the moon just 7.21023 N.
Does upthrust ONLY occur in water?
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!
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.
What is the upthrust needed to keep 1600n afloat?
To find the upthrust needed to keep a 1600 N object afloat, you need to consider the weight of the object. The upthrust must equal the weight of the object for it to stay afloat, so the upthrust required would be 1600 N.
Is upthrust force a non contact force?
No, upthrust would not be considered a non-contact force. It would be considered a contact force. It is making contact with an updraft of air.
