You are making a trip from one space station to another station 1 lightyear distant. You don’t want the trip to take too long: you only want to age one year during the voyage. What should be your speed relative to the space stations?

You are the astrogator on a starship that has just left a space station one hour ago heading toward galactic East at half light speed. The captain receives orders listing the coordinates of a rendezvous with another ship as (1 light-hour North, 2 light-hours East). The coordinates, of course, are measured relative to the space station, and the captain wants them translated into coordinates relative to your starship. What do you tell him?

#1. One lightyear is defined to be the distance light can travel in one year. (10 points) What is this distance in meters? How long does it take for light to get to the Moon? #2. Multiply 1.783 x 102 * 4.4 x 10-3, taking into account significant figures. (10 points) #3. What is the surface area of a sphere of diameter 2.4 x102 cm? (10 points) #4.

Wendy took a trip from one city to another, a distance of 740 mi. She traveled part of the way by bus, which arrived at the train station just in time for Wendy to complete her journey by train. The bus averaged 30 mi/h, and the train averaged 95 mi/h. The entire trip took 9 1/ 2 h. How long did Wendy spend on the train?

You are in a space station far from earth that generates an artificial gravity by rotating. On this space station your apparent weight is 460 N. If the engines that rotate the space station malfunction, causing the speed of rotation to double, what will be your apparent weight?

Artificial gravity is a must for any space station if humans are to live there for any extended length of time. Without artificial gravity, human growth is stunted and biological functions break down. An effective way to create artificial gravity is through the use of a rotating enclosed cylinder, as shown in the figure. Humans walk on the inside edge of the cylinder, which is sufficiently large (diameter of 2235 meters) that its curvature is not readably noticeable to the...

Suppose you are an astronaut being paid according to the time you spend traveling in space. You take a long voyage traveling a speed near that of light. Upon return to Earth, you're asked how you would like to be paid: according to the time elapsed on a clock on Earth or according to your ship's clock. Which should you choose to maximize your paycheck? Please explain why!

Cap Resources Suppose you take a trip to a distant universe and find that the periodic table there is derived from an arrangement of quantum numbers different from the one on Earth. The rules in that universe are: 1. principal quantum number n 1,2,... (as on Earth); 2. angular momentum quantum number 0,1,2,... ,n- 1 (as on Earth); 3. magnetic quantum number me = 0, 1,2, ...,l (only positive integers up to and including are allowed); 4. spin quantum number...

Suppose you take a trip to a distant universe and find that the periodic table there is derived from an arrangement of quantum mumbers different from the one on Earth. The rules in that universe are: 1. principal quantum number n = 1,2,...

You've decided to build a radio to listen to your favourite FM radio station, which broadcasts at 93.90 MHz. For the tuner, you'll be using an RLC circuit, but the only inductor you happen to have on hand has a value of 0.510 μH. Unfortunately, there's another radio station — which you don't want to listen to — at a nearby frequency of 93.50 MHz. To prevent any interference from this 93.50 MHz radio station, you want the peak current...

You've decided to build a radio to listen to your favourite FM radio station, which broadcasts at 97.30 MHz. For the tuner, you'll be using an RLC circuit, but the only inductor you happen to have on hand has a value of 0.210 μH. Unfortunately, there's another radio station — which you don't want to listen to — at a nearby frequency of 96.90 MHz. To prevent any interference from this 96.90 MHz radio station, you want the peak current...
