Answer:
Reversal of Earths magnetic field
Explanation:
Earth’s magnetic field reverses direction approximately every 2 million years. Every time Earths magnetic Field reverses, the magnetic direction of new sea floor along mid-ocean ridges also reverses. These alternating layers of magnetized seafloor can be used to map out boundaries of diverting plates.
A is correct.
When the car stereo is turned on, the chemical energy from the battery is transformed to electrical energy to make the stereo on, then the energy is transformed to sound so you can year it.
Answer:
(B) Boundary work
(D) Heat
Explanation:
Boundary work and heat quantitatively describe the transition between equilibrium states of thermodynamic systems. They are not only a function of the initial and final states, but also of the successive intermediate states through which the system passes, this is, depend on the path taken to reach one state from another. Thus, are path functions.
Answer:
680.6 N
Explanation:
The net force here is the resultant force. Taking that the two given forces act perpendicular to each other then the resultant is the hypotenuse. Therefore, where d is the magnitude of downward force and s is the magnitude of the sideways force. Substituting 631 N for downward force and 255 N for sideways force then
Therefore, the magnitude of net force is equivalent to 680. 6 N
The statement ‘The three major scales used to measure
earthquakes are Mercalli Scale, Richter Scale and Magnitude Scale’ is true. These
three scales used to measure the seismic waves released by the earthquake.
