Answer:
d. stops
Explanation:
Since initially, water flows downward in a parabolic trajectory due to gravity. When both container and water is in free fall, they are both subjected to the same gravitational acceleration g. Therefore, water acceleration with respect to the container is zero. Water would stop flowing (with respect to the contained) but it's still falling along with the container.
It will take the battery 15 hours to discharge completely.
<h3>Energy stored in a battery</h3>
Energy is defined as the ability or capacity to work. The formula for calculating the energy stored in a battery is expressed as;
Energy stored=Power×Time
Energy stored = ΔV * t
where
ΔV is the change in velocity
t is the time
Substitute
Energy stored = 12.0 * 90.0
Energy stored = 1080 W.h
Total power consumed by the headlight = 2 * 36
Total power consumed by the headlight = 72Watts
Determine the time it takes to dischage
Time = Energy Stored/Power
Time = 1080/72
Time = 15hrs
Hence it will take the battery 15 hours to discharge completely.
