Please i need help with question 33, image attached. Thank you.

I need help with question #12 from the submitted instruction image. Image number 2 is my work up to this point for information need to use. Can you show me how to do #12?

38 A student wants to measure the height of a building. He walks out a distance of 48.5 m from its base and shining a flashlight beam towards the top. When the beam is elevated at an angle of 41.0° with respect to the horizontal, the beam just strikes the top of the building. If the flashlight is held at a height of 2.03 m, find the height of the building. * O

In the following three scenarios, an object is located on one side of a converging lens. In each case, you must determine if the lens forms an image of this object. If it does, you also must determine the following. • whether the image is real or virtual • whether the image is upright or inverted • the image's location, q • the image's magnification, M The focal length is f = 53.0 cm for this lens. Set both q and M to zero if no image exists. Note: If q appears to be infinite, the image does not exist (but nevertheless set q to 0 when entering your answers to that particular scenario). (a) The object lies at position 53.0 cm. (Enter the value for q in cm.) 9 = M = cm Select all that apply to part (a). U real U virtual O upright inverted no image

Please help me with this problem, and double check your answers, i have had many issues with tutors in the past giving incorrect answers, and thats of no use to me then

That is the same answer I got and it's wrong. I rounded to 23 since you can't take 22.72 pictures and I still got it wrong. We must be doing something different from what the book wants us to do. :-(

Please answer all parts to question 1. Show all work and highlight your answers. Thank you in advanced!

An object that is 5.0 cm high is placed 20.0 cm from a bi-convex lens (a positive, focusing lens) with a focus of 10.0 cm. Calculate the position of the image. O-6.7 cm O-20 cm O 20.0 cm O 15.0 cm O 10.0 cm

H G F A E D In the image above, a light ray moves from a material with an index of refraction n2 = 1.46 into an material with an index of refraction n1 = 3. angle A + B = 90 degrees. %3D andgle B+C = 90 degrees. %3D angle C = 2 Calculate the angle of refraction, F. Give your answer with one decimal place.
