Please answer the following questions

1. Give examples of an objects that are going through the following energy conversions. Be sure to describe each example in enough detail to make it clear how each form of energy is demonstrated. e Gravitational potential energy into kinetic energy. e Thermal energy into gravitational potential energy. 2. Choose your lowest mass star. e (Calculate the mass energy produced by this star over the course of the main sequence part of its life. e Determine how many times more or less than the Sun this energy is. The Sun produces 1.26 x 10744 J in its lifetime. e Note: This question is a preparation for the Mass Energy constellation question so you can use the tutorial for that assignment to help you here. 3. Consider riding in an elevator rising in a tall building. It speeds up to 2 m/s, then continues rising at this speed. e What are the two forces acting on you? (Hint: one force pushes up on you and another pulls down on you. Remember that forces are pushes and pulls, not objects. Possible forces include: weight, tension, normal, friction) e As the elevator is speeding up, which force is stronger? How can you tell? (Hint: because it's accelerating, which of Newton's Laws apply? Newton's laws tell you the relationship between the acceleration and the net, or total, force.) e Once it reaches a constant speed, which force is stronger? How can you tell? e Which force is stronger: you pushing on the floor or the floor pushing on you? How can you tell? 4. Select the lowest mass star in your constellation. e Would a planet with an orbit of 1 year be more or less than 1 AU from this star? Explain why. e Would you expect a habitable planet (one with a surface temperature comparable to the Earth) be more or less than 1AU from this star? Explain why
