Property Energy (J) Rest mass (kg) Speed (m/s) Wavelength (m) Momentum (kg-m/s) Photon Electron/nTask 2: Special Relativity 1. Suppose that you have been chosen for a space mission to a distant planet. Due to the length of time you'll be away from Earth you must carry out physical activity every day. On earth your, strength and conditioning trainer has determined you must do 90 minutes of exercise every day. If the vehicle is travelling at 0.80 o how much time, according to a timer on the space vehicle should you be active to meet your physical activity requirement? contart.ca-car-t.com-avegh.com 2.

In a TV tube an electric potential difference accelerates electrons froma rest poetion towards a screen. Just before reaching the screen, the electrons have a wavelength of 1.2 x 10m. Determine the kinetie energy of the electrone just before they reach the screen. Your final answer should have units of ev Note: For any required calculation, be sure to include a complete solution process with a summary statement and a final answer with the correct significant figures ning ACTION/nTask 4: Developments in Modern Physics 1. Two atomic clocks are synchronized. One is placed on a satelle, which is around the earth at high speed for a whole year. The other is placed in a lab and remains atrast, with respect to the earth. You may assume that both clocks can measure time accurately to many significant digits. a. Will the two clocks still be synchronized after one year? Explain your reasoning b. Imagine that the speed of light was much slower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satelle? Explain your reasoning, using a calculation. 2. Use Max Planck's quantum theory to explain the following behaviour of photoelectrons. a Low-intensity light does not release any photoelectrons. What will happen if the light is made brighter? Explain your reasoning b. Low-intensity light releases photoelectrons. What will happen if the light is made brighter? Explain your reasoning. Low-intensity light does not release any photoelectrons. What will happen if the frequency of the light is gradually increased?
