Magine yourself in a future where technology has advance such that we can travel near the speed of light. The starship Explorer travels at 99.5% the speed of light ( ). You are the top science officer on at trip to Trappist-1 star system which contains 7 Earth like planets! Trapist-1 is 40 light years away. The Explorer reaches max speed at launch and you measure the distance to Trapist-1. What distance will you measure? How long will it take you to get there? Once you arrive you send at a radio wave signal back to Earth, how long will it take for them to receive it? You spend 4 years exploring the system and return back to Earth at the same speed. How much total time will your mission have taken according to the people on Earth? What is your favorite part of Einstein's theory of relativity?

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

What happens when a rubber rod is rubbed with a piece of fur?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
