Physics On a cold day when a room temperature is 15oC, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15oC, because metals are good conductor of heat plastics have a higher thermal conductivity than metals plastics have a lower density than metals metals have higher thermal capacity than plastics metals are good conductor of heat plastics have a higher thermal conductivity than metals plastics have a lower density than metals metals have higher thermal capacity than plastics ANSWER DOWNLOAD EXAMIANS APP
Physics Two metallic wires made from copper have same length but the radius of wire 1 is half of that of wire 2. The resistance of wire 1 is R. If both the wires are joined together in series, the total resistance becomes 5R/4 R/2 2R 3R/4 5R/4 R/2 2R 3R/4 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 Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts behaves like insulating media No radiation of heat takes place Air layer between two shirts works as good conductor Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts behaves like insulating media No radiation of heat takes place ANSWER DOWNLOAD EXAMIANS APP
