Why a Dyson sphere is impossible?
Why a Dyson sphere is impossible? Maddox points out that a Dyson sphere is physically impossible. To keep this shell in orbit around the Sun at any distance in the Habitable Zone would require some force counteracting gravity and pushing outwards on the sphere. In stars, this is radiation pressure. Is the Death Star a […]
Why commutator is needed?
Why commutator is needed? All generators produce a sine wave, or AC currents when the rotor turns in the magnetic field. The commutator on the DC generator converts the AC into pulsating DC. The commutator assures that the current from the generator always flows in one direction. What is a commutator in math? In mathematics, […]

What is the surface tension of ethanol?
What is the surface tension of ethanol? 415. Ethanol–Mercury. 20 °C. 389. Water–1,2-Dichloroethane. Which has more surface tension water or honey?
