Scientist a believes she has discovered a new procedure that is better than a procedure currently in use by physicians. she tests her procedure on several occasions and achieves excellent results. her procedure could be accepted as the best when a community of scientists a) accept scientist a’s procedure automatically because of her credentials. b) carry on further discussion, using many trials if experimentation is needed. c) carry on further discussion, using only a few trials if experimentation is needed. d) reject scientist a’s procedure; once a procedure is put into place, it can’t be altered with new evidence.

B) carry on further discussion, using many trials if experimentation is needed.

Explanation:

To know if the procedure is the best, the hypotheses raised there must be verified in many ways, choosing experiments that do not provide us with ambiguous or incomplete results. It is very important that any other person can repeat it, since a scientific discovery is not valid until another scientist has replicated it.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
