State whether the following statements are true or false.
1. On the solstices, the sun's rays are perpendicular to the equator, and someone residing on the equator would see the midday sun directly overhead.
A. True
B. False
2. Photovoltaic systems suffer numerous losses that reduce the actual electricity produced.
A. True
B. False
3. All photovoltaic cells made of silicon produce a voltage of about 0.5 volts per cell regardless of cell size.
A. True
B. False
Answer (2)
The correct answers are as follows: 1) B. False, 2) A. True, and 3) B. False. The first statement is incorrect due to the sun's position during solstices; the second is correct due to losses in photovoltaic systems; and the third is incorrect because voltage can vary based on different factors. Understanding solar positions and photovoltaic efficiency is crucial in geography and physics.
