Since vectors are defined by their direction and magnitude, what does having multiple starting and ending points to create the same vector tell you about how you can manipulate vectors on graphs?

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

50 inches should be the resultant vector

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.
