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.

Why does salt give more upthrust?
Salt dissolves in water, increasing the density of the water. The increased density of the water creates more buoyant force, leading to greater upthrust on an object.
How can the unit of upthrust can be derived?
Pascal is the s.i unit of upthrust
What upthrust is provided by a certain volume of gas?
The upthrust provided by a certain volume of gas is equal to the weight of the displaced fluid (Archimedes' principle). This upthrust helps objects float in water and is directly proportional to the volume of gas displaced and the density of the fluid.
Does upthrust increase as you go deeper into water?
Yes, upthrust, also known as buoyant force, increases as you go deeper into water because the pressure at greater depths increases due to the weight of the water above. This increased pressure causes objects to experience a greater upward force, resulting in an increase in upthrust.
What is the reason for upthrust?
There are several answering services that also have this question or similar ones on it. From answerbag.com, the question asked was: what is upthrust? The answers were: * Upthrust is the upward force exerted on an object in a fluid. It arises as a result of the difference in pressure exerted by the fluid on the surface of the object at different depth. * Up thrust is the force that pushes objects up and makes them seem to loose weight in a fluid (note - a fluid means a liquid or gas) When you are standing on the ground gravity keeps you down but upthrust stops you from falling into the earths core. In a way upthrust makes things hard!! Because if it didn't exist solids wouldn't be solid.An objects density effects how it floats. * Density = Mass * ------- * Volume * Upthrust is also called buoyancy. It is the upward force produced on an object in a fluid (such as air or water). The force is equal to the weight of the fluid displaced by the object. If that weight is greater than the weight of the object, the object will float in the fluid. If it is equal, it will sit suspended. If it is less, it will sink, but the object will weigh less than it would in a vacuum. Hence, it is easier to pick up a heavy object in water than in air - the amount of displaced water weighs more than the equivalent volume of air, therefore water produces a greater upthrust. In wiki answers the question asked was: = What does upthrust mean? = The answer was: Upthrust is a type of force that pushes upwards

Can upthrust be greater than weight?
Yes, upthrust can be greater than weight in fluids with high densities, such as water. This can result in objects floating or being pushed upwards in the fluid.
