Our solar system orbits the center of the Milky Way galaxy. Assuming a circular orbit 30,000 ly in radius and an orbital speed of 250 km/s, how many years does it take for one revolution? Note than this is approximate, assuming constant speed and circular orbit, but it is representative of the time for our system and local stars to make one revolution around the galaxy.

Suppose a spaceship of length L, is traveling at a high rate of speed v relative to an observer. To the observer, the ship appears to have a smaller length given by the following formula. L=L/1- where c is the speed of light Complete the parts (a) through (d). (a) What is the observed length L of the ship if it is traveling at 50% of the speed of light? Choose the correct answer below. O B. L=0 V5 OA L= OD. L=0 OC (b) What is the observed length L of the ship if it is traveling at 75% of the speed of light? O B. L=0 OA. L- OD. L-L OC. L= (c) In parts (a) and (b). what happens to L as the speed of the ship increases? Choose the correct answer below.
The kinetic energy of the ejecta from a supernova explosion is about 10^44 joules. Use the formula for kinetic energy to determine the typical speed at which matter is ejected from a supernova with a mass of 10 Msun. Compare that speed with the Sunʹs orbital speed around our galaxy. Based on your comparison, do you think the galaxyʹs gravity would be strong enough to retain the supernova debris if there were no interstellar medium to slow it down? Explain.
Write down Lorenzt transformation equations of special theory of relativity. Can a person, in principle, travel from Earth to the galatic center (which is about 23000ly distant) in 100 years? Try to calculate what is the constant speed it need to make the trip. Explain "mass is equivalent to energy".
A2. A light beam falls radially inwards towards the center of a black hole. First it passes shell A at a distance rA from the center of the black hole. It then passes the shell B at a distance rB from the center of the black the hole. We call the two shell passes event A and event B. Where large is the time interval between these two events and how can did you figure it out? Explain with a maximum of 3 sentences (plus any equations if you wish).
