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).
The crate will move to the left because the force to the left (25N) is greater than the force to the right (10N). The net force acting on the crate is the difference between the two forces: 25N (left) - 10N (right) = 15N to the left.

put your hand there to stop it.
T = R x F T = 0.5m x 15N T = 7.5 N*m
4 N upward
-5 -15n = 10add 5 to both sides-15n = 15divide both sides by -15n = -1
The table provides a support force of 15N to balance the weight of the book, according to Newton's third law. The net force on the book is zero because the support force is equal in magnitude but opposite in direction to the weight of the book, resulting in a balanced force system.
torque = force * lever length torque = 15 * 55 torque = 825 n-cms

A resultant force of 15N cannot be produced by two forces of 10N and 5N. The possible resultants of these forces are 5N (when the forces are in opposite directions) and 15N (when the forces are in the same direction).
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.
