Answer: We can define the solar constant as a measure of the luminous flux density.
Explanation:
The solar constant or solar constant is the amount of energy radiated at the upper limit of the Earth's atmosphere per unit time perpendicular to the unit surface, at the Earth's mean distance from the sun. Amounts to 1367.7 W / m² ± 6 W / m². The sun's constant includes all kinds of electromagnetic radiation, not just visible light. The average value is 1,368 kW / m2 and changes slightly with solar cycles. The amount of these constant changes over one year and has different benefits.
Option A is the correct answer.
Answer:
E.two angles are vertical angles if, and only if they are not adjacent angles
Answer:
a force
Explanation:
Because if we apply force then only an object can slow down, speed up or change direction
Scientists have designed solar cells to trap solar energy and convert it to D electrical energy. Its D because converting something has to do with recharging something and electronics have to charge. I hope I helped.
