Scientist A believes she has discovered a new procedure that is better than a procedure currently in use by physicians. She test

s 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.

Answer:

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.

What displacement in cm would occur with a 75 N/m spring if you placed a 300 N weight on the spring?
ollegr [7]

Surface tension=75N/m

Weight=300N

\\ \bull\tt\longmapsto Surface\:Tension=\dfrac{Weight}{Displacement}

\\ \bull\tt\longmapsto Displacement=\dfrac{Weight}{Surface\:Tension}

\\ \bull\tt\longmapsto Displacement=\dfrac{300}{75}

\\ \bull\tt\longmapsto Displacement=4m

\\ \bull\tt\longmapsto Displacement=400cm

pantera1 [17]

Answer:

d) v1 = v2 = v3

Explanation:

This can be answered using conservation of energy. We calculate the mechanical energy E=K+U (sum of kinetic and gravitational potential energies) at the original and final points, and impose they are equal.

At the original point we have, for the three balls:

E_i=K_i+U_i=\frac{mv_i^2}{2}+mgh_i=\frac{mv^2}{2}+mgh

At the final point we have, for the three balls:

E_f=K_f+U_f=\frac{mv_f^2}{2}+mgh_f=\frac{mv_f^2}{2}

Since we have E_i=E_f, and E_i is the same for all balls, then E_f is the same for all balls, which means that v_f, the final velocity, is the same for all balls.
