A 2.0 m first-class lever has a load of 600 N located 0.5 m from the fulcrum.  (a)    State the Law of the Lever. [1] (b)    Draw a diagram of the lever, showing the load, effort, fulcrum, effort arm, and load. (you do not need to submit the diagram, but it may help you answer the questions) (c)    Determine the effort force needed to balance the load. [2] (d)    If this lever has an actual mechanical advantage of 2, determine the percent efficiency of the lever. [2]

If two 100 Ω resistors are placed in parallel, their total resistance changes by what factor compared to the same two 100 Ω resistors placed in series with each other:
