A converging lens has a focal length of 14.0 cm. Locate the images for object distances of (a) 14.0 cm, (b) 4,67 cm, and (c) 28.0 cm, if they exist. For each case, state whether the image is real or virtual, upright or inverted, and find the magnification.
A vertical spring (spring constant =175 N/m) is mounted on the floor. A 0.470-kg block is placed on top of the spring and pushed down to start it oscillating in simple harmonic motion. Obtain the frequency (in Hz) of the motion
A 0.340-{\rm kg} mass is attached to a spring by a force constant of11.6 N/m. If the mass is displaced 0.258 m from equilibrium and released, what is its speed when it is0.119 m from equilibrium?
Consider two solid conducting spheres of radii r1 = 2 cm and r2 = 3 cm. Sphere 1 initially carries a net charge of +6 ?C, What is the voltage at the surface of sphere 1? What is the net charge on sphere 1? On sphere 2
