Please help and thanks The following text describes four different stars. Using the Hertzsprung-Russell diagram from earlier in the companion, determine whether each star is a giant, supergiant, white dwarf, or main sequence star:

Star 1:Color: Red-orange Surface temperature: 4000 K Luminosity: approximately 100 times dimmer than Earths Sun

Star 2:Color: Yellow Surface temperature: 5100 K Luminosity: approximately 75 times brighter than Earths Sun

Star 3:Color: White Surface temperature: 9000 K Luminosity: more than 10,000 times brighter than Earths SunStar 4:Color: Yellow Surface temperature: 6500 K Luminosity: approximately 1,000 times dimmer than Earths Sun

Where in its life cycle is Star 1?

Where in its life cycle is Star 2?

Where in its life cycle is Star 3?

Where in its life cycle is Star 4?

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)

When an orange rolls off a table, its potential energy is converted into?
