- Use Wien's Law to calculate the peak wavelength of light coming from the Sun. Assume T=5800 K for the surface temperature of the Sun. Wein's displacement law says that the blackbody temperature and peak wavelength multiplied together give a constant of 0.29 cm-K. (K is degrees Kelvin). Convert the wavelength from part A into a frequency. The product of wavelength and frequency for electromagnetic radiation is a constant, the speed of light (c), 3 x 10^10 cm/s.Let's say a spaceship is approaching Sagittarius A*. How close to this black hole must the spaceship get to experience time twice as slowly?Do you think I can type a 4000-word research paper trying to answer, " What percentage of the mass of a star is converted to electromagnetic energy?" If not how can improve this question to reach 4000 words? If so how should I approach this question?
- Please answer within 90 minutes.Calculate the number of miles in a light year using (see picture for the equation) mi/s as the speed. Hint: The number of seconds in a year,365days,will be useful.thank you for this explanation. however, i don't really see how it answers the question: does it match the reasoning?
- If Jim could drive a Jetson's flying car at a constant speed of 330 km/hr across oceans and space, approximately how long (in millions of years, in 106 years) would he take to drive to a nearby star that is 8.7 light-years away? Use 9.461 × 1012 km/light-year and 8766 hours per year (365.25 days).Can someone help with this?
