The number of ping pong balls needed to get a steel cube to float would depend on the mass of the steel cube.
No, they are not bouyant. They won't float on water, but they will float on mercury.
Well balls float-cos the force of upthrust from the water is pushing them up-and is stronger than gravity.The surface area increases the upthrust-which is why pumped balls float better than deflated.
They float at different densities. If the density of the water/antifreeze mix is too weak, the number of balls floating will indicate that, if the mix is correct, they'll indicate that.
Soccer balls never really float but they do stay in the air for a short period of time. This is mainly due to the compressed air inside the a ball.
Yes and they float
because of the density of oxygen.
balls, bottle caps, paper, boats
E-balls, or Environmental Balls, are balls which float on the top of liquids in open process tanks. Their purpose is to reduce evaporation and/or heat loss from the surface of the liquid in the tank.
Certain WEIGHTS of bowling balls float. Bowling balls have a volume of 6250 cm3. An equal amount of water would weigh 6.25 kilograms. A bowling ball that weighs less than 6.25 kilograms--8-pound, 10-pound and 12-pound balls--will float. 14-pound and 16-pound balls, having a density higher than 6.25 kilograms, will not float.
The density of tennis balls is approx. 0,38 g/cm3 an can float on water.
they both float and have less density than water
Not all cooked food float in soup. Fish balls are made from fish paste. There are tiny air bubbles trapped inside the paste. When they are cooked, the air bubbles made the fish ball lighter and as a result, the fish balls float in soup.So the fish balls will float in the soup . :D
