According to Wien's Law, how many times hotter is an object whose blackbody emission spectrum peaks in the blue, at a wave length of 450 nm, than a object whose spectrum peaks in the red, at 700 nm...

According to Wien's Law, how many times hotter is an object whose blackbody emission spectrum peaks in the blue, at a wave length of 450 nm, than a object whose spectrum peaks in the red, at 700 nm...

A formula from physics is λmax × T = 0.0029. This formula is called Wien's law, and it relates the wavelength of the peak of a blackbody spectrum (your answer to question 1), to the temperature of...

Earth, Jupiter, Saturn, and Uranus all revolve around the sun. Earth takes 1 year, Jupiter 12 years, Saturn 30 years, and Uranus 84 years.

?-The questions in this homework quiz all refer to the following graph: http://www.up-00.com/VERzSCdj It shows a black body spectrum for an imaginary star. (In reality, while real...

I am trying to calculate the number of asteroids in our solar system based on how often they hit the earth. I feel like there must be a mathematical relationship between how many objects there are...

The Hubble Space Telescope is a reflecting telescope in orbit about the earth so that its resolution would not be limited by turbulence in the atmosphere. Its objective diameter is 2.4 m. For visible...

I am having trouble showing that the baryon to photon ratio is η= nb/nγ ~ 2.7x10-8Ωbh2 where nb and nγ are the number density of baryons and photons respectively, Ωb is the baryon...

if a car traveling at constant speed goes 70 miles in 2 hours, how far will it go in 24 hours

I am stuck on this one question on my science homework, and I would like to know how to answer it so I can be ready for a quiz, too. Please help. Suppose a comet passes the sun every...

In what order are the planets from the sun

I wanna ask about Astronomy! If Space is really elastic kind of, and the Gravitation pull of planets is due to the bend they cause because of their mass in Space, would it be true...

Stellar Evolution

and have examples of how the sun physically moves matter and how the sun chemically moves matter

If the mass of the second object is very small compared with the first mass, then, to a good approximation, P2 = a3 / M1. Solving for the mass, we get M1 = a3 / p2 . Use this mass formula to...
