4.Write your conclusions about the conservation of the mechanical energy over the time between the first and the last oscillations that you observed. What do you think can account for the percentage differences

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.

What about a rubber band, can it change its shape? is it a solid?
