Question 7 (1 point) You recently read that a new possibly habitable planet was discovered. The planet, Burt, receives 2100 W/m2 from it's companion star. If planet Burt has a a radius of 7000 km and acts like a blackbody (emissivity-1) and thus radiates same amount of energy it absorbs, what is its average suraface temperature. For comparison the earth has a surface temperaure of 278 K.

The nearest star to Earth besides the Sun is Proxima Centauri, which is a distance of approximately 4 light years away. A planet that may be able to sustain liquid water on its surface was discovered in 2016 orbiting Proxima Centauri. According to observers on Earth, a spaceship that travels at 0.9c should be able to reach the planet in 3.6 years. How long would the trip take according to astronauts on board the spaceship?

A uniform magnetic field points directly into your paper (make a sketch). A 7 turn coil of wire with a radius of 14.2 cm lies in the plane of the paper. Over a period of 0.00035 seconds, the field is increased from 0.300 T to 1.10 T. How much emf is induced in the coil while B is changing? A-0.12 volts B- 0.91 volts C-28 volts D- 16,000 volts E- 250 volts Which way is the induced emf (or induced...

Astronomers have discovered a planetary system orbiting a star, which is at a distance of 5.2 × 1018 m from the earth. One planet is believed to be located at a distance of 1.9 × 1010 m from the star. Using visible light with a vacuum wavelength of 557 nm, what is the minimum necessary aperture diameter that a telescope must have so that it can resolve the planet and the star?

Astronomers have discovered a planetary system orbiting a star, which is at a distance of 3.9 × 1019 m from the earth. One planet is believed to be located at a distance of 1.9 × 1010 m from the star. Using visible light with a vacuum wavelength of 543 nm, what is the minimum necessary aperture diameter that a telescope must have so that it can resolve the planet and the star?

One of the primary goals of the Kepler space telescope is to search for Earth-like planets. Data gathered by the telescope indicates the existence of one such planet named Boralis orbiting a star 120 ly from our solar system. Consider an interstellar spaceship leaving Earth to travel to Boralis. The ship can reach 0.70c almost instantly and can also decelerate almost instantly. The ship is 175 m long in its reference frame. (a) What is the length of the moving...
