An open rectangular tank that is 4 m long, 2 m wide
and 4.8 m high, is initially three-quarters filled
with water. Find the depth of water in the tank after
4000 litres of water are added to it.

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
