than the buoyant force. 2. Hot-air balloon The atmosphere is filled with air that exerts buoyant force on any object. A hot air balloon rises and floats due to the buoyant force (when the surrounding air is greater than its weight). It descends when the balloon weight is more than the buoyant force. It becomes stationary when the weight = buoyant force. The weight of the Hot-air balloon can be controlled by varying the quantity of hot air in the balloon. 3. Hydrometer A hydrometer is

blood vessels to make blood flow easier. Devices such as balloons are used to extend the blood vessels’ circumference. This procedure uses catheters wherein the balloons are attached at the tip and inserted in the affected vessel. Once the balloon is in its proper place‚ it will then be inflated to expand the blood vessel. Other procedures use lasers and blades to cut off the plaques off the vessel walls. But according to studies‚ using balloons for this procedure is far more safer than using blades

The correlative situation is that when there is more air been blew into the balloon‚ there is an increase in the balloon’s pressure resulting in its expansion in size from equilibrium and risk of explosion. Nevertheless‚ the balloon would remain normal despite stretching and not explode. Equivalently‚ an individual’s attempt to adjust in his or her conduct due to the social sanctions is analogous to the balloon stretching due to additional air and hence increased pressure.

The American Civil War provided many chances for improvements in technology‚ but some of the new technology that was developed was in military technology. Many of the new developments involved taking previous technology and developing it for the military. An example would be lights used in lighthouses.
