- Mars has the largest volcanoes in the solar system. (T/F)Chapter 37, Problem 012 The length of a spaceship is measured to be exactly 1/2 its rest length. (a) What is the speed parameter ß of the spaceship relative to the observer's frame? (b) By what integer factor do the spaceship's clocks run slow, compared to clocks in the observer's frame? (a) Number Units (b) Number UnitsTitans exosphere has a temperature of about 174 K. What is the thermal speed of hydrogen (in km/s) in Titans exosphere ? The mass of a hydrogen atom is 1.67 x10-27kg and Boltzmann's constant is k=1.38 x10-23 Joule/Kelvin
- Eventually, space telescopes have shown that Venus is shrouded by a very dense atmosphere (see Figure 6). To pierce through the dense clouds and study its surface, astronomers had to use radio imaging (see Figure 7). Venus’ atmosphere is transparent to radio waves. Research and explain briefly how, through radio imaging, Venus’ surface could be reconstructed.Why is Mars red?The planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…
- Saturn is even further at 1434X109m from the sun. Calculate the approximate strength of the greenhouse effect on Jupiter.
