The energy produced by the headlamp at the end of 5 minutes is determined as 1,440 J.
<h3>
Energy supplied by the lamp</h3>
The energy supplied by the lamp is calculated as follows;
E = Pt
E = IVt
where;
- I is current = 0.4 A
- V is voltage = 12 V
- t is time = 5 mins = 5 x 60 s = 300 s
E = 0.4 x 12 x 300
E = 1,440 J
Thus, the energy produced by the headlamp at the end of 5 minutes is determined as 1,440 J.

Explanation
If you graph the force on an object as a function of the position of that object, then the area under the curve will equal the work done on that object, so we need to find the area under the function to find the work
Step 1
find the area under the function.
so
Area:
so
therefore, the answer is

The acceleration due to gravity is given as:
g = GM/r²
<h3>
Derivation of gravitational acceleration:</h3>
According to Newton's second law of motion,
F = ma
where,
F = force
m = mass
a = acceleration
According to Newton's law of gravity,
F<em>g </em>= GMm/(r + h)²
F<em>g = </em>gravitational force
From Newton's second law of motion,
F<em>g </em>= ma
a = F<em>g</em>/m
We can refer to "a" as "g"
a = g = GMm/(m)(r + h)²
g = GM/(r + h)²
When the object is on or close to the surface, the value of g is constant and height has no considerable impact. Hence, it can be written as,
g = GM/r²
