Your Questions About Solar Energy Materials And Solar Cells
Mark asks…
How can I calculate how fast a solar battery toy car can move?
For a science project I have been given two solar cells, one of 1 V and 0,4 A and another of 2V and 0,55 A. We are two use these solar cells (and other material) to build a toy car.
We also need to calculate how fast this car will move and I don’t have a clue where to start.Is there anyone out there that can help me how to think? What factors will decide how fast the car will move?
Thanks from

How did the cycling of solar energy through the biosphere begin?
Photosynthesis and cellular respiration are the same chemical reactions headed in opposite directions. Photosynthesis takes carbon dioxide and water and produces carbohydrates and oxygen. Cellular respiration takes carbohydrates and oxygen and produces carbon dioxide and water. Respiration is the exothermic reaction. Photosynthesis requires the input of energy from the sun in order to proceed. In the economy of ecology, why are both reactions necessary? How did the cycling of solar energy through the biosphere begin? How can it be best maintained today?
–Please help me understand this alittle better.
