The bottom surface of a car will not be of smooth to make it Float. By the way, even a small boat, whose said surface is smooth, even at zero velocity, due to buoyancy force exerted by the water, it floats. If one really wants to make a ca (whose density is more than the water at displaced area)with smooth boat like bottom surface, the velocity should be such that the water should would exert a buoyancy force as if car density is less than water.
Yes
no, it will float on the surface
A Wooden float is the flat surfaced tool that is used for smoothing the surface of concrete prior to it setting. A wooden float produces a reasonably non slip surface as it pulls up sand out of the concrete mix to the surface.
21.4mm or .84" from the float bowl mating surface to the top of the float
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
Surface tension
Yes, a pin can float on water due to its low density and small surface area. Surface tension of water helps support the weight of the pin, allowing it to float.
You would be lying on the surface tension of the water, with the pressure of your body evenly distributed across the water. The surface tension allows you to float effortlessly.
Due to surface tension, the upper surface of water acts like a stretched membrane which enables it to float a swing needle.
The surface of the opocorn or raisin allows bubbles to form and they stick to the surface. This allows them to float.
The surface area of the raft displaces the water forcefully which causes float
Yes, a log can float on water if its density is less than that of water. Logs are typically buoyant because they have a lower density than water, allowing them to float on the surface.
