How does the resultant displacement change as the angle between two vectors increases from 90° to 120°? A. None of these are correct.
B. The resultant decreases.
C. The resultant increases.
D. The resultant stays the same magnitude, but its direction changes.

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

conservation of mass

mass before something happens = mass afterwards

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
