The high spark voltage supplied to the spark plugs of an automobile is increased from the battery voltage by the principle of

The answer that best fits the blank provided is the term INDUCTION. What is being described above is what we call the Principle of Induction. This is when a coil is being used in order to create and increase electric potential difference. This is when battery voltage comes in.

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
