Physics It is easier to roll a stone up a sloping road than to lift it vertical upwards because Work done in both is same but the rate of doing work is less in rolling. Work done in lifting the stone is equal to rolling it. Work done in rolling is more than in lifting. Work done in rolling a stone is less than in lifting it. Work done in both is same but the rate of doing work is less in rolling. Work done in lifting the stone is equal to rolling it. Work done in rolling is more than in lifting. Work done in rolling a stone is less than in lifting it. ANSWER DOWNLOAD EXAMIANS APP
Physics On a clean glass plate a drop of water spreads to form a thin layer whereas a drop of mercury remains almost spherical because: cohesion of water is greater than its adhesion with glass. density of mercury is greater than that of water. cohesion of mercury is greater than its adhesion with glass. mercury is a metal. cohesion of water is greater than its adhesion with glass. density of mercury is greater than that of water. cohesion of mercury is greater than its adhesion with glass. mercury is a metal.
