Vectors vs. scalars
1. most of the quantities used to describe motion can be categorized as either vectors or scalars. a
vector is a quantity that is fully described by both magnitude and direction. a scalar is a quantity that is fully
described by magnitude alone. categorize the following quantities by placing them under one of the
two column headings.
displacement, distance, speed, velocity, acceleration
scalars
vectors

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

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
