1 Find the acceleration of an object if there is a force of 20 newtons in one direction and 10 newtons in the opposite direction. The mass if 2 kg.

5m/s/s

Explanation:

10N bc you subtract 10N from 20N and you get 10

a=f/m

F=10N

m=2kg

10/2=5

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
