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 No radiation of heat takes place Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts works as good conductor Air layer between two shirts behaves like insulating media No radiation of heat takes place Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts works as good conductor ANSWER DOWNLOAD EXAMIANS APP
Physics It is more difficult to walk on a sandy road than on a concrete road because the friction between sand and feet is less than that between concrete and feet. sand is soft and concreter is hard. the sand is grainy but concrete is smooth. the friction between sand and feet is more than that between concrete and feet. the friction between sand and feet is less than that between concrete and feet. sand is soft and concreter is hard. the sand is grainy but concrete is smooth. the friction between sand and feet is more than that between concrete and feet.

Physics A parallel-plate capacitor of capacitance C1 is made using two gold plates. Another parallel-plate capacitor of capacitance C2 is made using two aluminium plates with same plate separation, and all the four plates are of same area. If rg and ra are respectively the electrical resistivities of gold and aluminium, then which one of the following relations is correct? C1>C2 C2>C1 C1 = C2 C1pa = C2pg C1>C2 C2>C1 C1 = C2 C1pa = C2pg ANSWER DOWNLOAD EXAMIANS APP
