The first thing to do is define a positive direction. The right is often defined as being positive, so we shall use that in this problem. We can now define the forces. Let F1= 100lb and F2 = -30lb (It is negative because it is pointing to the left.) Now simply add up the forces: Fnet = F1+F2 Fnet = 100lb + (-30lb) Fnet = 70lb

This is a trick question. A transformer transforms voltage and currents. The magnetic field strength of 15 Newtons (a measurement of force, or power) is not changed - in other words what you put into a transformer (in terms of power) you get out the other side (minus losses). so 15N in, 15N out. You can also think of it this way: voltage is applied to the primary side, which induces a magnetic field. This magnetic field induces a voltage in the secondary side. So the magnetic field produced in the primary side is the same magnetic field that produces the secondary voltage. Thus the answer is in the question - the magnetic field is 15N (there's only one).
15 N 75 W is the Caribbean Sea.

4 N upward

The buoyant force is the weight of the displaced water. That's 15n, and it points upward. That upward force combines with the downward 20n due to gravity. The net force on the object is 5n downward.
T = R x F T = 0.5m x 15N T = 7.5 N*m
-5 -15n = 10add 5 to both sides-15n = 15divide both sides by -15n = -1
torque = force * lever length torque = 15 * 55 torque = 825 n-cms

The box will accelerate to the left as though a single 5 N force was pushing to the left. (5 N of each force are cancelled out, leaving 5 N of the force pushing left.)
He did 5n per m. Joe's ratio of work to distance is 5:1.
You could do so many. Here are some examples: 15n=105 15n+105=1005 15n-105=270 Hope this is what you were looking for. :) Good luck!
