If a boy has a body weight of 500 N what upthrust does he need to float?
Same as his weight
Why the balloons filed with hydrogen does not rise indefinitely?
To rise, they need something to float on - i.e., air.
Would a piece of wood that's mass is 89 grams float?
If it is made of wood, it is very likely that it will float. The mass alone (89g) is not enough information to determine if something will float. You will also need to know the volume. Divide the mass (in grammes) by the volume in (cubic centimetres) to give you a value of grammes/cc Water has a density of 1g/cc. If the wood has a value less than this then it will float in water.
Why can you lift heavy objects in water that you couldn't lift outside of water?
It's all to do with forces. Everything on the planet is exposed to the force of gravity pulling it down. That force can be overcome quite easily. Imagine you have a heavy box pulling towards the earth with a force of 40N (N = Newtons - the measurement of force). It's hard to carry, you have to overcome 40N of 'pull' to do it, but you can put it on a table without it crashing through. This is because the table pushes back with exactly the same amount of force. If you put it on the floor, the floor pushes back with the same amount of force. If this didn't happen we'd have all been pulled to the Earth's core by now! Let's call this pushing back force upthrust. So if you put an object on a solid the upthrust equals gravity and the object doesn't move. What about water? Water has an upthrust, just not as much as a solid object. So our 40N box when put in water won't have the full 40N upthrust that it had on the table and sit on the surface. Instead it might have an upthrust of 20N. So the box sinks till it reaches a solid. But to pick it up will only need 20N of force, because the water pushing up at 20N will do half the job for us. It takes less force to move and so it feels 'lighter'. So it's easier to move something in water because the upthrust of the water is included in the number of Newtons of force that you need to use.
How can you make a feather sink in water?
As long as the feather stays all by itself, it will never sink in water, because its density is much less than the density of water. If you really need to sink it, then you must tie it to something much more dense, like a rock or a fishing sinker.
If you and a raft weighed 1600 newton's how much upthrust would you need to float?
1600n
If a boy has a body weight of 500 N what upthrust does he need to float?
Same as his weight
Why ship is floating?
An object in water displaces its weight in water. If its volume is greater than the volume of water displaced this way, it floats. Ships, despite being made of heavier materials, utilize their size and their relative empty insides to float this way.

How much water do you need to float an egg?
You need just enough to cover the surface area of the submerged part.
How does an egg float on water?
well you will need something that is sticky and heavy also an item is to wrap around an egg that might make it float.i say it migth float because the light objects float and the heavy one sink.so yes it will
How much water bottles would a 113 pound person need to float on. Not just to float but be able to sit on a raft made out of water bottles?
About 15.
How do you make a float like a state float Nevada?
To make a float you will need a shoe box and a knife. You will need to cut the box in the shape of Nevada.
Does a float need carbonation?
it can there are many ways to make a good float
How much fluid does an object need to displace to float?
A volume equal to its own weight (Archimedes' Principle).
At Quassy do you have to bring a float for the BulletBowl or do you need to bring a float from home?
Yes
Does the 750 brute force float?
yes but if you need it to float you better have it snorkeled
