Draw the net force arrow on the picture to the left.

calculate the net force and state the direction.

net force = _
net force direction = _

The answer to your question is: Net force = 0 N; There is no direction because there in no force.

Explanation:

Net force = 7 N - 4 N - 3 N

               = 0N

There is no direction, because there is no force.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
