Q.Two 26.0 cm focal-length converging lenses are placed 16.5 cm apart. An object is placed 39.0 cm in front of one lens. Where will the final image formed by the second lens be located? What is the total magnification?
Q. A proton moves at constant velocity in the +y direction, through a region in which there is an electric field and a magnetic field. The electric field is in the +x direction, and has magnitude 700 V/m. The magnetic field is in the -z direction, and has magnitude 0.75 T.
what is the Fnet?
Determine the resolution limit set by diffraction . what average force do you need to apply to stop the sled? Utilize the concepts of impulse and momentum.
A father and a daughter balance a teeter-totter to illustrate the principle of the lever. If the father whose weight is 150 N is 8 m from one end, how far away on the opposite side of the fulcrum should the 50-N daughter stand to balance the teeter-t..
