Is EMF sensitivity a real thing?
Is EMF sensitivity a real thing? Electromagnetic hypersensitivity (EHS) is a claimed sensitivity to electromagnetic fields, to which negative symptoms are attributed. EHS has no scientific basis and is not a recognised medical diagnosis. Does electromagnetic waves effect on human body? The main effect of radiofrequency electromagnetic fields is heating of body tissues. Despite extensive […]

What happens to the volume of a gas when you double the number of moles of gas? Le Chatelier’s Principle states that: a) When a system at equilibrium is disturbed , a new equilibrium constant is established. What happens to the volume of gas when you double the number of moles of gas while keeping […]
Is there anything more powerful than gamma rays?
Is there anything more powerful than gamma rays? The measurement is exceedingly difficult since cosmic rays can outnumber gamma-rays at these energies by a factor of 10,000 to 1 or more! As the gamma-ray is making its way to our telescopes, it has to traverse through space, where there are photons and particles all around […]

Who found solar energy?
Who found solar energy? A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. How do we convert solar energy into electricity? When light energy from the sun strikes a photovoltaic solar cell, it energizes the cell […]
