- QUESTION 1: Apply the energy interaction model to the two-masses-over-a-pulley situation. Model this system as if the pulley is massless and frictionless, so you won't have to worry about energy systems associated with the pulley system. Take the initial state to be you just release the masses (what is vi? what is delta-v?) Take the final state to be when the masses have a distance d and have speed but before they hit anything or out of string. (since d denotes a distance, it is a positive number: delta-y = +/- d, as appropriate) 1. Create a particular model of the phenomenon described above by constructing a complete Energy-Interaction Diagram for each of the mass sets using the initial and final states above.QUESTION 2: Apply the energy interaction model to the two-masses-over-a-pulley situation.

Watch your "minus signs"!anwer according to the blanks: A new type of force was discovered by physicists with the following expression: where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction of a massless Higgs Boson (a type of particle) and a black hole. Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution To determine the work done we apply the following W = Blank 1dx Evaluating the above, we get W = Blank 2| Blank 3 | + Blank 4eBlank 5 + Blank 6xBlank 7 for the limits from xi to xf substituting x1 and x2 as the limits, the work done is expressed as W = Blank 8| Blank 9/Blank 10 | + ( Blank 11x1 - Blank 12 ) + Blank 13( x15 - x25 )

- Before we introduced the Friedmann equation, we gained some intuition with a Newtonian example of an expanding sphere of uniform density that feels its own gravity. Suppose the sphere is currently static; it has expanded to its maximum size and is about to recollapse. Given that its total energy per mass is U, and its density is currently \rhoρ, what is its current size? Write your answer in meters, using one decimal place. Values: U = -82 J/kg \rhoρ = 545 x 105 kg/m3 Please show work as I have trouble following alongWhat do you mean by CPT invariance?
