Physics Static Equilibrium- Will give brainliest to right answer! 1. A uniform 40.0 N board supports two children weighing 500 N and 350 N. The support (often called the fulcrum) is under the center of gravity of the board, and the 500 N child is 1.50 m from the center.
a. Determine the upward force (the normal force) exerted on the board by the support.

b. Determine where the 350 N child should sit to balance the system.

explanation:

heat is transmitted by radiation

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

the answer is 12 as i may remember
