Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen?

Mutt have to apply twice the larger force than applied by Jeff

Explanation:

Since Mutt and Jeff want to reach the destination at same time

As given that wagon carried by Mutt is twice heavy than wagon of Jeff

Now to reach the destination both of the wagon must be pulled with same acceleration so that both wagon can cover equal distance in equal interval of time

Now we know that

since mass of wagon carried by Mutt is twice heavy than wagon of Jeff so here the force applied by Mutt must be twice larger than the force applied by Jeff.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
