I think the correct answer would be B. The process of elastic rebound is being shown by the student. It is a theory that is used to explain earthquakes. It focuses on how energy is being spread in times of earthquakes. As the rocks on the fault experiences shift and force, these rocks would be accumulating energy causing it to deform reaching the internal strength and eventually exceeding it. At that moment, a rapid motion would happen along the fault, which releases the energy, then the rocks would go back to its original shape or the undeformed state. This theory is the first theory that sufficiently was able to explain earthquakes.
Inertia is the property of an object that basically describes its resistance to change its state of motion.
For instance, if an object is still, inertia describes the "attitude" of the object to stay still (a force should be applied in order to move it). Similarly, if an object is moving by uniform motion (with constant speed), inertia refers to the "attitude" of the object to keep its uniform motion (again, a force should be applied to the object in order to change this state of motion).
Give a turn signal for at least the last 100 feet before you make your turn to let other drivers know what you are going to do.
Making turns, turning a corner may seem to be a simple operation, however many accidents or traffic crashes are caused by drivers who do not turn correctly.
Answer:
1.697s
Explanation:
We use the second equation of free fall under gravity as follows;
Since the ball fell freely, u = 0m/s, therefore equation (1) reduces to
Given that h is the total height the ball falls through in time t seconds.
However, according to the stated problem the ball falls halfway in 1.2s, this simply implies that the ball falls through a distance of 
in 1.2s. Hence we can write the following, given that 
;
We can now proceed to find the time t for which it falls through h = 14.112m as follows;
