A ball is dropped from a height h above the surface of the earth. Ignoring air drag, the curve that best represents its variation of acceleration is

Standing on a polished stone floor one feels colder than on a rough floor of the same stone. This is because

• Thermal conductivity of the stone depends on the surface smoothness

• Specific heat of the stone changes by polishing it

• The temperature of the polished floor is lower than that of the rough floor

• There is greater heat loss from the soles of the feet when in contact with the polished floor than with the rough floor

• Positive

• Negative

• Netural

• Random
