Answer: Scientists found evidence of Earths magnetic field reversal in rocks on the ocean floor at plate boundaries. These rocks have alternating polarity due to magnetization that occurred during their cooling period. Using radio metric dating, scientist estimate that reversals occur approximately every several hundred thousand years.

Answer:
Density = 1027.3 [kg/m3]
Explanation:
To solve this problem we must use the concept of density which is defined as the relationship between mass and volume, which can be determined by the following equation.
density = m/v
m = mass = 308.19 [gramm] = 0.30819 [kg]
v = volume = 300 [mL] = 0.3 [Lt] = 0.0003 [m3]
density = (0.30819/0.0003)
density = 1027.3 [kg/m3]

Answer:
h = 0.25 [m]v = 3.26 [m/s]
Explanation: In order to solve this problem, we must remember that mechanical energy is defined as the sum of kinetic energy plus potential energy.
