A scientist compares a fossil to another fossil. The comparison gives the scientist information that fossil A is younger than fossil B and C . Which scientific concept is the scientist using? * 1 point
A. absolute dating
B. relative dating
C. the law of superposition
D. the principle of uniformitarianism

B. relative dating

Explanation:

The scientist is using the concepts of relative dating to determine the age of the two fossils he has.

Relative dating involves ascribes ages to rocks or fossils based on their relationship in a sequence. Relative dating is made possible by series of laws and principles. Some of the principles are "the law of superposition", "principle of original horizontality", "Principle of fossil and fauna succession", "Principle of lateral continuity".

These principles helps to ascribe the right relative ages to rock strata and the fossils they contain.

Distance covered, s = 8ft - 4ft = 4 ftinitial velocity, u = 34 ft/sthe acrobat is moving upwards and therefore, a = -g = -9.81 m/s^2 = 32.19 ft/s^2applying equation of motion; s = ut -1/2gt^2then,4 = 34t -1/2*32.19t^24 = 34t - 16.095t^2rearranging; -16.095t^2 + 34t - 4 = 0solving the quadratic equation; t = {-34 +/- sqrt [34^2 - 4(-16.)]}/2(-16.095) = 1.06 +/- 0.93 = 0.13 or 1.99the acrobat will take 0.13 seconds to be at 8 ft above the ground. additionally, once at the maximum height, the acrobat will move down and be at the same spot (that is height) after 1.99 seconds moving down.
