The hawaiian islands formed as a result of tectonic plate movement over a volcanic hot spot. the rate of plate movement can be calculated using the distance that an island is from the hot spot and the age of the island. a scientist determines that one of the islands is 4860 kilometers from the hot spot and is 6.5 × 107 years old. which of the following statements are true? select three that apply.
a. the rate of plate movement is approximately 7.5 cm per year.
b. the rate of plate movement is approximately 7.5 × 10–5 km per year.
c. in a million years, the plate has moved a distance of approximately 75 m. d. in a million years, the plate has moved a distance of approximately 7.5 × 107 mm.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
