Physics The sensation of weightlessness in a spacecraft in an orbit is due to the Presence of gravity outside but not inside the spacecraft Fact that spacecraft in the orbit has no energy Absence of gravity outside Acceleration in the orbit which is equal to the acceleration due to gravity outside Presence of gravity outside but not inside the spacecraft Fact that spacecraft in the orbit has no energy Absence of gravity outside Acceleration in the orbit which is equal to the acceleration due to gravity outside ANSWER DOWNLOAD EXAMIANS APP
Physics Cloudy nights are warmer compared to clear cloudless nights, because clouds mainly Absorb heat from the atmosphere send it towards earth Prevent cold waves from the sky descending on earth Produce heat and radiate it toward earth Reflect back the heat given by earth Absorb heat from the atmosphere send it towards earth Prevent cold waves from the sky descending on earth Produce heat and radiate it toward earth Reflect back the heat given by earth ANSWER DOWNLOAD EXAMIANS APP
Physics When hot liquid is poured into a thick glass tumbler, it cracks because glass : Has high temperature coefficient of expansion Has a very low specific heat Has low temperature coefficient of expansion Is a bad conductor of heat so only inner surface expands Has high temperature coefficient of expansion Has a very low specific heat Has low temperature coefficient of expansion Is a bad conductor of heat so only inner surface expands ANSWER DOWNLOAD EXAMIANS APP
