The type of current described by the given statements is D.C. (or direct Current).
Explanation:
There are two different types of currents. They are Alternating Current (AC) and Direct current (DC) . Alternating current varies alternately, as the name suggests. DC is used for devices that need low voltage, like the chargers of a mobile phone. Domestic power supply is AC .
The time must be measured with respect to gravity. As it falls, it has free fall that is the force acting on it will be the gravity.With the distance in account, d = 1/2 gt²
