Solved in 3 steps with 2 images
- Tutorial Star A has a temperature of 6,000 K. How much energy per second (in J/s/m²) does it radiate onto a square meter of its surface? If the temperature of Star A decreases by a factor of 2, the energy will decrease by a factor of Star B has a temperature that is 5 times higher than Star A. How much more energy per second (compared to Star A) does it radiate onto a square meter of its surface? Part 1 of 4 The energy of a star is related to its temperature by E = OTA where o = 5.67 x 10-8 J/s/m²/K4. Part 2 of 4 To determine how much energy Star A is radiating, we just plug in the temperature to solve for EA. EA J/s/m²Suppose you were given a spectrum of a planet. The spectrum has a collection of absorption lines. Describe how you would use this simulation to identify what lines were present (or absent) in the spectrum, and therefore what atoms were present (or absent) on the planet.I'm unsure where to start in this proble. By comparing equations, does that mean Vo=5? How can we tell what acceleation is? Does the power rule allow us to make 1/2t^2 just 1t? I've attached images below
- In class we found an expression for the 'garden hose angle', ψ, and showed it had a typical value close to 45° (or 225°) near 1 AU. How would we expect this angle to change for very slow solar wind speeds? Choose the best answer below: A. ψ → 0° B. ψ → 90° C. ψ → 180° D.

How does a solar sail control it'd direction? How fast can it go? What is a solar sail made of, how big it has to be? What are the advantages? How expensive is it? Why do we want solar sails and where would they take us? What is the future of solar sailing and are there any existing missions? How can you relate solar sails with solar panels? How are they both like and unlike?What is Hopkinson’s law.Explain with the help of equation(Sir, I want more details)
