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 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 someone weighed 85 pounds on Earth how much would they weigh on the moon in newtons?
To find your weight on the Moon, we have to divide 9.8 (gravity on the Earth) by 6. That answer has to be multiplied by 85 pounds. that answer is done in newtons as you are finding the weight on the moon. newtons is unit for 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.
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.
If one pound is the same as about 4.4 newtons about how much would a 20 pound dog weigh in newtons?
It would be 20*4.4 newtons = 88 newtons.
Will a submarine sink or float when its weight is greater than the upthrust acting on it?
When the weight of any object surrounded by fluid is greater than the buoyant force on it, it sinks. (The buoyant force is just the weight of the fluid that would be in that space if the submerged object were not there.)
Would ice float higher in water or corn syrup?
Firstly there is no such thing as floating higher; something either floats or it doesn't. Buoyancy (pronounced boy-an-see) on the other hand, describes the ability or tendency of an object to float in a liquid. Objects float in a liquid when they are less dense than the liquid. For example an ice cube will float in both water and corn syrup because it is less dense than both. The ice cube will have greater buoyancy in corn syrup because corn syrup is more dense than water.
