- How many days would it take for the particles to reach earth if thr solar wind speed increased to 2000 km/s?arrow_forwardA solar flare can release 1025 J. How many megatons of TNT would be equivalent?arrow_forwardCalculate the total amount of radiative energy per second intercepted by Mars from the Sun using the flux of radiation from the Sun at Mars' orbital radius. Flux of radiation from the Sun at Mars' orbital radius is 597 W m-2. The luminosity of the Sun Ls = 3.8×1026 W. Mars orbits at a distance of 2.25×1011 m (1.5 AU) from the Sun. Note: Consider carefully the cross-sectional area Mars presents to the outwards flow of radiative energy when answering this question.arrow_forward

The sun is a sphere with an estimated mass of 2.00×1030 kg. What exactly is the conversion process for this?arrow_forwardfrom d to f please thank youarrow_forwardIf a sunspot has a temperature of 4,430 K and the sunspot can be considered a blackbody, what is the wavelength (in nm) of maximum intensity of the sunspot's radiation?arrow_forward
- Explain neutrino oscillations and their consequences.arrow_forwardIn a typical solar oscillation, the Sun’s surface moves up or down with a speed of 0.1m/s . If you were to try to measure this speed using the Doppler shift of the absorption line for Iron which has a wavelength of 557.6099nm, what is the longest wavelength you will see?arrow_forwardEven though neutral hydrogen is the most abundant element in interstellar matter, it was detected first with a telescope, not a visible light telescope. Explain why.arrow_forward
- How close to the Sun would a spacecraft have to go to reach the distance at which the flux of solar energy is 20 times as large as the solar energy flux at the Earth?(arrow_forwardSomeone suggests that astronomers build a special gamma-ray detector to detect gamma rays produced during the proton-proton chain in the core of the Sun, just like they built a neutrino detector. Explain why this would be a fruitless effort.arrow_forwardNow suppose that all of the hydrogen atoms in the Sun were converted into helium. How much total energy would be produced? (To calculate the answer, you will have to estimate how many hydrogen atoms are in the Sun. This will give you good practice with scientific notation, since the numbers involved are very large! See Appendix C for a review of scientific notation.)arrow_forward
