A diverging lens (f = -11.0 cm) is located 19.0 cm to the left of a converging lens (f = 30.0 cm). A 2.60-cm-tall object stands to the left of the diverging lens, exactly at its focal point.
(a) Determine the distance of the final image relative to the converging lens.
(b) What is the height of the final image (including the proper algebraic sign)?
A light plane (mass = M) makes an emergency landing on a short runway. With its engine off, it lands at speed v0. A hook on the plane snags a cable attached to a sandbag (mass = m) and drags the sandbag along. The coefficient of friction between the ..
consider a theoretical head on collision between two carts of equal mass and equal speed. what is teh total momentum before collision
Calculate the kinetic energy that the earth has because of (a) its rotation about its own axis and (b) its motion around the sun. Assume that the earth is a uniform sphere and that its path around the sun is circular. For comparison, the total ene..
