Drag each tile to the correct location.
gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud.
its temperature stays well
below 14 million kelvin.
its volume shrinks and density
increases due to gravity.
its temperature surpasses
14 million kelvin
its hydrogen atoms shed their electrons.
it is spread out, with a grea e volume and
lesser concentration of elements.
its hydrogen atoms retain their electrons.
gas cloud 1
gas cloud 2

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
