An object is located 10 cm from a converging lens with a focal length of 12 cm. To the right of the converging lens by 30 cm is a second converging lens of focal length 10 cm. Find the location of the second image. Note that the object 1 is inside the focal length of lens 1 so is the special case\" 14.3 cm, to the right of the second lens 11.3 cm, to the right of the second lens 14.3 cm, to the right of the rst lens 5"}. 11.3 cm, to the right of the first lens An object of mass of mass 0.12 kg is moving at 1.8 x 10 m/s. What is its kinetic energy in Joules? In eV? 2.7 x 1015 J, 1.7 x 1034 ev O none of these are correct 1.99 x 1015 J, 1.36 x 1034 ev 1.99 x 1015 J, 1.36 x 10-34 evLight from a red laser passes through a single slit to form a diffraction pattern on a distant screen. If the width of the slit is increased by a factor of two, what happens to the width of the central maximum on the screen? The new width is 1/2 times the old width. [3:3 The new width is 2 times the old width. The new width is 4 times the old width. The new width is 1/4 times the old width. A laser with a wavelength of light of 690 nm illuminates two parallel slits. Interference fringes are observed on a screen 3.30 m away from the slits. The distance between the adjacent bright fringes in the center of the pattern is 1.80 cm. What is the distance between the slits? 0.127 m 0.127 mm 0.000127 mm O 1.27 m
