How does a life belt help in swimming?
Asked by anusha | 10 Oct, 2013, 11:54: AM
Expert Answer
Life belt increases the surface area and thus decreases the density of the body. This results in more buoyant force exerted by the fluid than the gravitational force exerted by the object and helps in floating.
