Answer:
C
Explanation:
The order is this: Displacement --> Velocity --> Acceleration. The velocity directly affects the displacement and the acceleration directly affects the velocity. (changing the acceleration changes the velocity which also changes the displacement).
To go forward in our order, find the slope of the curve/line. To go backwards, find the area under the curve/line. In this case, we are trying to find the displacement of the object, so we should find the area of a velocity-time graph.

Answer:
B. solar energy → electric energy → light and heat energy
Explanation:
The solar energy received from the solar rays is transformed into electrical energy, through a photovoltaic process that is part of the solar panel and other elements. Then the electric energy generates currents that pass through the electrical circuit and this transformation generates light in electric bulbs. Since energy conversion processes are never 100% efficient for the electric energy in the bulb is transformed into heat, for that reason the electric bulb emits part of its energy in the form of light and heat.
