1.	Amercury thermometer is placed in a gravity free hall without touching anything. As temperature risesmercury expands and ascend in thermometer. If height ascend by mercury in thermometer is h thenbywhat height centre of mass of "mercury and thermometer" system descend?hish io further kent on a
Answer» <p>Here thermometer is placed in gravity free region</p><p>So there is no external force on the system.</p><p>When there is no force on the system its center of mass will retain its position and does not move if the whole system is initially at rest.</p><p>So here the displacement of center of mass of the system will be ZERO.</p> <p>Sahi hai sir</p>
