Physics The ringing of an electric bell in an enclosed evacuated glass bell jar is not heard outside because The ringing is not loud enough The bell jar is too small The glass of the bell jar absorbs the sound waves There is no air or any other gas in the bell jar The ringing is not loud enough The bell jar is too small The glass of the bell jar absorbs the sound waves There is no air or any other gas in the bell jar ANSWER DOWNLOAD EXAMIANS APP
Physics Why two thin shirts can keep us warmer than a single thick shirt in winter ? Air layer between two shirts works as good conductor No radiation of heat takes place Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts behaves like insulating media Air layer between two shirts works as good conductor No radiation of heat takes place Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts behaves like insulating media ANSWER DOWNLOAD EXAMIANS APP
