Physics A stone floor feels cold to the bare feet but a carpet on the same floor feels warm. This is because The human body maintains a constant temperature The stone conveys the heat away from the feet more rapidly than the carpet The carpet is a better conductor of heat than the stone The floor and carpet are at different temperatures The human body maintains a constant temperature The stone conveys the heat away from the feet more rapidly than the carpet The carpet is a better conductor of heat than the stone The floor and carpet are at different temperatures ANSWER DOWNLOAD EXAMIANS APP

Physics It is easier to roll a barrel full of coal tar than to pull it because more surface area of the barrel is in contact with the road when it is pulled the rolling friction is much less than the sliding friction coal tar is a liquid and it flows in the barrel when it is rolled the full weight of the barrel comes into play when it is pulled more surface area of the barrel is in contact with the road when it is pulled the rolling friction is much less than the sliding friction coal tar is a liquid and it flows in the barrel when it is rolled the full weight of the barrel comes into play when it is pulled ANSWER DOWNLOAD EXAMIANS APP
