Point charges g1+2.00uc and g2-2.00uc are placed at adjacent corners of a square for which the length of each side is 4.50 cm. point a is at the center of the square, and point b is at the empty corner closest to 92. take the electric potential to be zero at a distance far from both charges. a) what is the electric potential at point a due to ql and q2? b) what is the electric potential at point b? c) a point charge q3 = -4.00 uc moves from point a to point b. c) how much work is done on q3 by the electric forces exerted by q1 and 92?

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap

Can you receive a shock severe enough to prevent you from releasing the wire from an ordinary outlet with dry hands? a. no b. yes explain

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
