Apinhole camera is just a rectangular box with a tiny hole in one face. the film is on the face opposite this hole, and that is where the image is formed. the camera forms an image without a lens. (a) make a clear ray diagram to show how a pinhole camera can form an image on the film without using a lens. (hint: put an object outside the hole, and then draw rays passing through the hole to the opposite side of the box.) (b) a certain pinhole camera is a box that is 25 cm square and 20.0 cm deep, with the hole in the middle of one of the 25 cm x 25 cm faces. if this camera is used to photograph a canada goose that is 18 cm high and 1.5 m in front of the camera, how large is the image of this bird on the film? what is the lateral magnification of this camera?

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
