5. Oscar runs in the LA Marathon every year. Oscar's strategy for finishing the 26.2 mile race is to just keep running at a constant velocity the whole time! Oscar is able to run at a constant velocity of 5.24 miles per hour for the whole race. How long does it take Oscar to finish the race? Ans: 6. Mr. Thorne is training for a triathlon. If he ran 12 miles/hr for 6 hours on one of his practice runs, how far did he train for the day? Ans: 7. How much time does it take a Metro train going 15 m/s to travel 45 meters towards Downtown Los Angeles? Ans: 8. A motorcycle travels 60 meters in 15 seconds before it stops at a light. What is its average velocity during that time period? Ans:

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
