- Parallax from Jupiter. Suppose you could observe stellar parallax from the orbit of Jupiter. How would it differ from the stellar parallax we observe from Earth? Would it be easier or more difficult to measure stellar distances? Explain.How long does it take light from the sun 93 million miles away to the earthAnyone able to help me with this question
- explain each physics formula by saying what each variable means/stands for and explain the formula as a whole, please.Solution from part A: E=-KE = PE/2 Solution from part B: =3/2kt a. (NOTE: Treat the cloud as two equal masses interacting gravitationally across a distance equal to the radius of the cloud.) Use your result from part a to write down the condition for gravitational collapse in terms of the kinetic and potential energies (NOTE: This condition is an INEQUALITY) b. Use your result from part b in order to replace the kinetic energy with its temperature equivalent in your expression for the collapse condition. c. Solve the expression in ii above for the mass.Earth tugs the Sun around as it orbits, but it affects the radial velocity of the sun by only 0.09m/s. How large a shift in wavelength does this cause in the Sun's spectrum at 575 nm?
