Elliptical, because the shape of the galaxy isn’t like the others. It is unique to its own and doesn’t have another to compare to
<u>Answer</u>
C = 6.00; θ = 270˚
<u>Explanation</u>
A vector is described by giving both its magnitude and direction.
A = 3.00; 270°
B = -3.00; 90°
C = A - B. From this expression, it can be seen that we have already reversed the direction of B. So vector C is in the direction of A.
C = A - B
C = 3.00 - (-3.00)
= 6.00

The child needs a push from time to time because kinetic energy generates friction, witch takes kinetic energy and turns it into thermal energy, which floats away and can never be obtained again. So without the kinetic energy, and without someone pushing him/her, the child will only go slower and slower until he/she stops.
