Physics An electron microscope gives higher magnification than an optical microscope, because : The electrons have more energy than the light particles The wavelength of electrons is smaller as compared to the wavelength of visible light It uses more powerful lenses The velocity of electron is smaller than that of visible light The electrons have more energy than the light particles The wavelength of electrons is smaller as compared to the wavelength of visible light It uses more powerful lenses The velocity of electron is smaller than that of visible light ANSWER DOWNLOAD EXAMIANS APP
Physics A metal ball and a rubber ball, both having the same mass, strike a wall normally with the same velocity. The rubber ball rebounds and the metal ball does not rebound. It can be concluded that Both suffer the same change in momentum The rubber ball suffers greater change in momentum The initial momentum of the rubber ball is greater than that of the metal ball The metal ball suffers greater change in momentum Both suffer the same change in momentum The rubber ball suffers greater change in momentum The initial momentum of the rubber ball is greater than that of the metal ball The metal ball suffers greater change in momentum ANSWER DOWNLOAD EXAMIANS APP
