An object is 0.9 m away from a particular lens. The lens produces an image of that object 30 cm on the other side of the lens.a. Is this lens converging or diverging?b. Find the focal length of this lens.c. Is the image real or virtual?d. Sketch a ray diagram of this situation.e. Suddenly, your sneaky lab mate replaces the lens described above with one that has a focal length of the same magnitude but opposite sign. (So the new lens is in the same location, but has switched its converging/diverging type.) Sketch a new ray diagram.f. Describe any changes in the location, orientation, or type of image produced by the lens. Calculate numerical values when possible.
The supersonic aircraft Concorde has a length of 63.0 when sitting on the ground on a typical day when the temperature is 16.0. What is the temperature of the Concorde's skin in flight
Two cylindrical glass beads each of mass m = 32 mg are set on their flat ends on a horizontal insulating surface separated by a distance d = 3 cm. The coefficient of static friction between the beads and the surface is μs = 0.3. The beads are the..

A particle is constrained to stay on a frictionless circular ring of radius R. Solve the appropriate Hamiltionian for this system, write the normalized wavefunction, and find the energy eigenvalues.
A 4.7-g object moving to the right at 18 cm/s makes an elastic head-on collision with a 9.4-g object that is initially at rest. What is the velocity of the 4.7-g mass after the collision
A 1500 microfarad capacitor and a 5600 microfarad capacitor are connected in parallel across a 12.0 V potential difference. Determine the total energy stored in the capacitors
A curve of radius 35 m is banked for a design speed of 64 km/h. If the coefficient of static friction is 0.34 (wet pavement), at what range of speeds can a car safely make curve.
