a force of 50n is applied 10nofe, a force of 100n is applied 35n of, a force of 300n is applied 45sofw, and a force of 250n is applied 75sofe to an object. what is the magnitude and direction of the net force applied to the object?

This did i unseated, sorry

To find speed, or mph, use distance/time.

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
