Want this question answered?
you put the object you want to float on another object and then you sell the object underneath
Generally, yes.
OF COURS NOT!it wud take that the temperature is -90c for it to freaze
It can freeze in mid-air if the temp. is below 32 degrees. Best is when it is below 0 degrees
No.
No.
An object stays in the air when the density of the object is at equilibrium with that of the air. A good example of this would be a light-weight, hollow container filled with 50% helium, and 50% oxygen. This would stay perfectly stationary, so long as there was enough helium to counteract the container's weight, in mid-air. However, if the helium level is greater than the air within the object, it will continue to float upward until the density of the object is equal to that of the atmosphere around it.
Crisis in Mid-Air was created in 1975.
Mid Pacific Air was created in 1981.
It isn't; both have the same mass regardless of the material surrounding them. Infact, the opposite appears true. The object suspended in water will seem lighter than the object suspended in air, because the density of water is greater than the density of air, which means objects will be more buoyant in water.If the statement in your question was true, everything would float in mid-air.
Yes. An object is in equilibrium if the velocity is constant. A constant velocity can occur if the forces balance on the object. Consider that the gravitational force is balanced by the "air resistance force", then there is no net force and thus no acceleration. Then the velocity at which this occurs will be a constant and thus the body will be in equilibrium.
If by "freeze" you mean "hover in place". Yes, a skilled pilot can hold the aircraft so still it appears to be figuratively frozen in place. The skill required is like that needed to balance an egg on a spoon...with the spoon turned upside down.
