For what reasons could a theory be changed or replaced? check all that apply. new technology is developed that provides more information about the theory. new experimental methods are designed to test a theory. a new, untested hypothesis is proposed. new information is discovered that does not support the theory. a single experiment produces results that differ from all previous experiments.

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

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.
