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.

Answer:
same as
Explanation:
According to Newton's 3rd law, the force that the Earth exert on the Sun would be equal (and in opposite direction) with the force that the Sun exerts on the Earth.
Also Newton's gravitational law states the formula for the attraction between objects with mass, is the same for both objects

Explanation:
Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. When the applied force is released, the whole system returns to its original shape.
Answer:
Use the principle of momentum
Initial momentum = final momentum
Momentum formula = Mass * Velocity
