The vertical dimension of the bracket is 12.3 cm and the screw is 4.9 cm up from the bottom of the bracket. a downward force f=140 n is applied to the bracket 5.2 cm from the wall. ignore the mass of the bracket. what is the horizontal component of the force that the screw exerts on the bracket? hint: imagine that the bracket is slightly loose at the screw that fastens it to the wall so that the shelf leans to the left a little bit. then think about where else on the bracket a force will be applied as the shelf leans to the left.

Iam on that question know can you tell me the answer i am realy strruglingasap

No. rocks can follow various pathways.

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.
