To increase the resolving power of a microscope, the object and the objective are immersed in oil (n = 1.54). If the limiting angle of resolution without the oil is 0.680 microradians, what is the limiting angle of resolution with the oil? Give your answer in radians; don't enter unit.
A 2.50g ice flake is free from the edge of a hemispherical bowl whose radius r is 31 cm. The flake-bowl contact is frictionless. What is the speed of the flake when it reaches the bottom of the bowl?
LASIK eye surgery uses pulses of laser light to shave off tissue from the cornea, reshaping it, What is the power of one laser pulse
Determine the greatest vertical displacement of the pendulum (height). The mass lost by the rocket during these 30.0 is negligible. What impulse does an engine impart to the rocket?
A constant torque of 21.4 N•m is applied to a grindstone whose moment of inertia is 0.125 kg•m2. Using energy principles, determine the angular speed (in revolutions per second) after the grindstone has made 19 revolutions. (Avoid friction.) Do no..

A 2.3 box, starting from rest, is pushed up a ramp by a 10 force parallel to the ramp. The ramp is 2.0long and tilted at 17 . The speed of the box at the top of the ramp is 0.80 .
When the starter motor on a car is engaged, there is a 330A current in the wires between the battery and the motor, What minimum diameter can the wires have if the voltage drop along the wires is to be less than 0.45V
find the work done to move the particle from x = 0 to x = 10.0 m by graphically determining the area under the F versus x graph. (Do this on paper. Your instructor may ask you to turn in this graph.)
A 21 kg sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 80.5 N and is directed at an angle of 30° above the horizontal. Determine the coefficient of kinetic friction.
A parachutist with a camera, both descending at a velocity of 12 m/s, releases that camera at an altitude of 120 m.
Expalin how many revolutions will the car have gone through when the magnitude of its total acceleration is 2.00 m/s^2?
A friend is standing on a giant skateboard that is initially at rest. If you avoid frictional effects with the floor, what is the momentum of the skateboard if your friend walks to the right on skateboard with a momentum of 150 kg.m/s? What is the..
