Use gauss's approach to find the following sun, without using formulas 1+3+5+...+2021

_____________________ occurs when light travels out of a gravitational field, loses energy, and its wavelength grows longer.   a. A magnetar   b. Time dilation   c. A gravitational redshift   d. An X ray burst   e. A pulsar wind

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.

The remaining lifetime of the Sun in seconds is 1.5 x 10¹7 sec. Convert this value into years. 0000000000000000 PLS HELP!

Please help me with this.

3- Consider a binary star system in which the two stars are seen to be 1.50" apart. Determine the actual physical separation of those stars (in AU) if this binary system is located 9.50 1.y. from us.

11. Bob is traveling in a space ship and observes emission from a cloud of atomic hydrogen gas a few light years away. He identifies the Balmer-beta emission line (from the n = 4 to n = 2 transition) and measures its wavelength to be 322 nm. How fast is Bob moving relative to the cloud of hydrogen? Is he getting closer or further away from the hydrogen cloud? (You may assume that Bob is moving directly toward or away from the hydrogen gas cloud. Recall that the ground state energy of hydrogen is -13.6 eV.)

Whats the wavelength of a photon of light that permits a hydrogen atom to go from its energy level 3 to its energy level 2? 434nm 121.6nm 486.1nm O 656.3nm Whats the wavelength of a photon that could make a hydrogen atom jump from energy level 4 to energy level 2? 656.3nm 121.6nm 102.6nm 486.1nm

5... Calculate the fraction of time a spacecraft spends in daylight given a celestial body with a radius 5,709 km at an altitude of 686 km. Use the extreme case (minimum alpha) when the angle between the orbit plane and the direction of the sunlight is 0.
