We are given that a force of 40 n is exerted at an angle of 42°. therefore, the force vector f can be represented as the hypotenuse of a right triangle with an acute angle 42°. the length of the hypotenuse would be
|f| =
.

answer: a. same unit

explanation:

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
