### Resolved Question:

1.A street lamp weighs 170 N. It is supported by two wires that form an angle of 130° with each other. The tensions in the wires are equal.

(a) What is the tension in each wire?_____N
(b) If the angle between the wires is reduced to 100°, what is the tension in each wire?_____ N
2. A 205 N box is placed on an inclined plane that makes a 25.0° angle with the horizontal. Find the component of the weight force parallel to the plane's surface._____N
3. Five forces act on an object.

(1) 59 N at 90°
(2) 40 N at 0°
(3) 75 N at 270°
(4) 40 N at 180°
(5) 50 N at 60°

What are the magnitude and direction of a sixth force that would produce equilibrium?
N at °
4.
