The answer is the option c. generator. Generator is a machine that
converts mechanical energy into electricity. The way it is made is
because the mechanical movement may be transformed in rotation of
magnets placed inside a coiled wire, and this induces the movement of
electrons through the coiled wire. As you know electricity is the flow
of electrons.
The displacement of an object is obtained by taking out the area of the rectangle plus the area of the triangle under the line.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Suppose the initial position of an object is zero, the starting velocity is 3 m/s and the final velocity was 10 m/s. The object moves with constant acceleration.
In velocity time graph, the slope determines the acceleration and the area under the curve gives the value for the displacement.
Thus, the displacement of an object is obtained by taking out the area of the rectangle plus the area of the triangle under the line.

Answer:
The road bank angle is 16.38⁰.
Explanation:
radius of curvature of the road, r = 50 m
allowable speed of car on the road, v = 12 m/s
The bank angle is calculated as;
where;
θ is the road bank angle
g is acceleration due to gravity = 9.8 m/s²
Therefore, the road bank angle is 16.38⁰.
