If every force pushing on an object is balanced by a force of equal magnitude pulling it in the opposite direction, then:
Check all that apply.
A. the object has no net force acting on it.
B. the object will be accelerating.
C. the direction of the object's motion will not change.
D. the velocity of the object will be constant.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present

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.
