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 rolling a stone is less than in lifting it. Work done in rolling is more than in lifting. Work done in lifting the stone is equal to rolling it. Work done in both is same but the rate of doing work is less in rolling. Work done in rolling a stone is less than in lifting it. Work done in rolling is more than in lifting. Work done in lifting the stone is equal to rolling it. ANSWER DOWNLOAD EXAMIANS APP
Physics It is easy to burst a gas-filled balloon with a needle than with a nail. It is because Gas is reactive with the needle. Needle exerts more pressure than nail on the balloon. Nail exerts more pressure than needle on the balloon. Nail is more longer than needle. Gas is reactive with the needle. Needle exerts more pressure than nail on the balloon. Nail exerts more pressure than needle on the balloon. Nail is more longer than needle. ANSWER DOWNLOAD EXAMIANS APP
