The reason a life jacket helps keep you afloat is?

Final answer:A life jacket helps you float in water by utilizing the principle of buoyancy. It is made of materials with lower density than water, which displace more water than their own weight, thus creating an upward force that helps you stay afloat.Explanation:The reason a life jacket helps keep you afloat is due tobuoyancy. When you're in a body of water, the upward force created by the water (buoyant force) comes into play. A life jacket is filled with a material that has a lower density than water, which means it displaces more water weight than its own weight, hence it floats. When you wear a life jacket, it transfers this buoyant force to you, helping you float.Consider this scenario for better understanding: A rock may be heavier than a small sponge, but if both are thrown into water, the rock would sink because its density is greater than water. The sponge, however, will float because its density is less than that of water, despite being larger in size. A life jacket essentially works in a similar manner.Learn more about Buoyancy here:brainly.com/question/36883204#SPJ11...
