To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition. ... With absolute age dating, you get a real age in actual
D is the answer

Answer:
D. 3 psi
Explanation:
Pressure is defined as force acting per unit area and is numerically expressed as:

where P represent pressure, F is force and A is area where the force acts. Substituting 300 lb for force and 100 sq.in for area then pressure,

Therefore, from the choices given, option D, 3psi is the right choice.
