Suppose the horizontal cable were reattached higher up on the wall. would the tension in the inclined cable increase, decrease, or stay the same?

Decrease  

Explanation:  

- As the angle is inclined, more force is exerted by the string in horizontal direction as a result, less force is exerted in the vertical direction, which means that the tension decreases.

-Tension is a pulling force experienced by means of a string or a pulley. The direction of tension will always be away from the mass, and the force will be upwards.

-Tension is 0 or same when the both the ends of a rope have equal forces so tension at the center of the rope becomes zero

-Tension is directly proportional to frequency.  

well you could find somebody who doesn't want theirs and ask for it or possibly trick a dealer into giving it to you for free.
