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?

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
