The energy of a foton is calculated by thefollowing formula: Efoton=h×(c/lapda). Fill in 7.0×10^-7 gives us Efoton=6.626×10^-34 (planck constant) × 7.0×10^-7=4.6×10^-40.
If im not mistaken plant cells go through a stage called photosynthesis meaning the cells can create it's own energy (food) off of water, Co2 and sunlight.
mixture of iron powder and sulphur heated it glows because sulphur and iron are more reactive metals that they shine and sulphur can react with water produce fire it's write
