How much time does it take a dropped object to fall 180 m on Earth? 18 s
36 S
10 s
6s

6s

Explanation:

Assume it is dropped from rest and the gravitational acceleration is 10

By the equation of motion under constant acceleration:

180 = (0)t+10(t^2)/2

t = 6 or -6 (rejected)

t = 6 s

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
