The graph gives the world population between 1950 and 2050. The numbers from today through 2050 are estimates. Assume that the projections on the dotted (upper) line are true. What might be one result of the population change?

Heat from the sun reaches earth to a. radiation b. convection c. conduction

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
