If two vectors a equals to 4 metre per second and b is equals to 7 metre per second be inclined at an angle of 60 degree to each other then determine the direction and magnitude of the resultant

Explanation:

a = 4m/s

b = 7m/s

R = ?

R = sq. 4*2 + 7*2 + 2 x 4 x 7 x cos60

R = sq 93

direction is the angle which is already given in question.

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.

your answer is, orbit around the nucleus
