Your flight to your friends house in Halifax has a short layover in Toronto. Your total flight time is 6.25 hours. The first flight to Toronto covers a distance of 2700km [35.0degrees S of E], and the 2nd flight to Halifax covers a distance of 1280km [10.0degrees N of E]. a) What was the total distance you travelled?
b) What was your displacement?
c) What was your average speed (in km/h)?
d) What was your average velocity (in km/h)?

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
