Three point charges with values q1 = 8.00 nc , q2 = 1.00 nc , and q3 = 5.00 nc are placed on three consecutive corners of a square whose side measures s = 5.00 m . point a lies at the fourth corner of the square, diagonally across from q2. point b lies at the center of the square. what are the values of the electric potential at point a and at point b? how much energy (supplied as work) is required to move a test charge q4 = 2.00 nc from point a to point b? assume the zero of electric potential is chosen to be at infinity.

We found the centripetal acceleration of the earth as it revolves around the sun. compute the centripetal acceleration of a point on the surface of the earth at the equator caused by the rotation of the earth about its axis. (enter the magnitude. the radius of the earth is 6,371 km.)

What happens when chlorine reacts with bromine? a. electrons move from the chlorine atoms to the bromine atoms. b. electrons move from the bromine atoms to the chlorine atoms. c. electrons are shared between the chlorine atoms and the bromine atoms. d. electrons become delocalized among the atoms.

Asubject in a clinical research trial experiences a serious, unanticipated adverse drug experience. how should the investigator proceed, with respect to the irb, after the discovery of the adverse event occurrence? a. do not report the adverse drug experience to the irb since it is a common adverse experience.b. report the adverse drug experience to the irb only if there are several other occurrences.c. report the adverse drug experience as part of the continuing review report.d. report the adverse drug experience in a timely manner, in keeping with the irb's policies and procedures, using the forms or the mechanism provided by the irb.
