How do electric field lines indicate the strength of the field? A. by how long the lines are B. by how close the lines are C. by the direction the lines are pointing D. by showing the charge that creates the lines

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

d) physical means can be used to separate the components of air.

not too sure thinking all accelerations are pointed down

gravitational energy

electrical energy

kinetic energy

ligh energy
