Using evidence from the article, defend the concept that Earth’s magnetic poles have swapped places over time.
Mamont248 [21]

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.

A motor pulls an 800 kg roller coaster train to the top of a 70 m hill. What is the change in the potential energy of the cars?
Angelina_Jolie [31]

Answer:

548800J

Explanation:

Given parameters:

Mass of roller coaster  = 800kg

Height of hill  = 70m

Unknown:

Change in potential energy  = ?

Solution:

The change in potential energy is the difference between the potential energy at the bottom and at the top.

Potential energy at the bottom is 0J

  So;

      Change in potential energy  = mgh - 0

m is the mass, g is the acceleration, h is the height

  Change in potential energy  = 800 x 9.8 x 70  = 548800J
