Physics Which one of the following statements with regard to Jet stream, an upper level tropospheric wave, is not correct? It follows the wave path near the tropopause at elevations of 8 km to 15 km. In summer, the polar front jet achieves its maximum force. It is narrow band of high-velocity wind. Jet streams are typically continuous over long distances.

Physics Why two thin shirts can keep us warmer than a single thick shirt in winter ? 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 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 ANSWER DOWNLOAD EXAMIANS APP
