Best ResponseYou've already chosen the best response.0Time lapse photography is made by placing a camera on a tripod and keeping the camera’s shutter open for a long time. If the camera is pointed in the direction of the stars, the stars appear to rotate around Polaris, also known as the North Star or the Pole Star.

Best ResponseYou've already chosen the best response.0dw:1438312164441:dw so this is what it may look like right, as it's pointed towards the stars, and is rotating around polaris, so that must be 90 degrees.

Best ResponseYou've already chosen the best response.0yeah thats what I though and the options were 30, 45, 90, and 180 so i thought it was 90 or 180

Best ResponseYou've already chosen the best response.0Ok cool, I think that makes sense :) we are upon agreement, but in any case could you post the right answer when you're done this problem, I'm still skeptical.

Best ResponseYou've already chosen the best response.0Use your answer from the previous question to estimate the length of time that the camera’s shutter was open. The shutter was open for ____ hours. (Round your answer to the nearest hour and enter only the number.)

Best ResponseYou've already chosen the best response.0If the shutter is open for 24 hours, the stars appear to make one complete rotation around Polaris.

Best ResponseYou've already chosen the best response.0No worries, so 360 is 24 hours, so all we have to do is \[\frac{ 90 }{ 360 } = ...\]

Best ResponseYou've already chosen the best response.0You just have to convert it in hours, that shouldn't be too bad

Best ResponseYou've already chosen the best response.0ohhh wow thats pretty easy just overthinking it thank you. Convert it from min to hours correct?

Best ResponseYou've already chosen the best response.0\[\frac{ 90 }{ 360 } = 0.25\] that means it's 25% of 24 hours, so now just multiply by 24 to get the answer in hours, 0.25(24).
