Physics Skating on ice is possible because The surface of ice is smooth Ice is cold The pressure on the ice due to skate melts the ice by lowering its melting point forming a thin film of water The pressure on the ice due to skate raises its melting point The surface of ice is smooth Ice is cold The pressure on the ice due to skate melts the ice by lowering its melting point forming a thin film of water The pressure on the ice due to skate raises its melting point ANSWER DOWNLOAD EXAMIANS APP
Physics Planets do not twinkle because They are nearer to earth and hence we receive a greater amount of light. They emit light of a constant intensity They are very far away from the earth resulting in decrease in intensity of light Their distance from the earth does not change with time They are nearer to earth and hence we receive a greater amount of light. They emit light of a constant intensity They are very far away from the earth resulting in decrease in intensity of light Their distance from the earth does not change with time ANSWER DOWNLOAD EXAMIANS APP

Physics It is easier to roll a stone up a sloping road than to lift it vertical upwards because 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. 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.
