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 […]

What is the percentage error in the surface area of a sphere?
What is the percentage error in the surface area of a sphere? SΔS=r2Δr=2×4=8% Was this answer helpful? What is percentage error in sphere? Volume of the sphere is V=43πr3. As per the rule for combination of errors for exponents ΔVV=3Δrr. =3 x 0.015. ΔVV=0.045. Percentage error =ΔVV×100=0.045×100=4.5% What is the error in volume? To calculate […]
Why do superconductors float?
Why do superconductors float? At normal temperatures, magnetic fields can pass through the material normally. When a magnet is placed above a superconductor at critical temperature, the superconductor pushes away its field by acting like a magnet with the same pole causing the magnet to repel, that is, “float”—no magical sleight of hand required. Can […]
