Assuming a laser source, write out the equations for the lateral resolution and axial resolution for a confocal imaging system (assume incident beam waist wi, lens focal length f, and wavelength ? -800nm). for the axial resolution, you can use twice the rayleigh range of the beam. b) next, write out the equations for the lateral resolution and axial resolution for an oct system. consider the same beam, lens, and wavelength parameters as for case 'a'. in addition, assume that the laser has a coherence length of 100nm c) for low na (0.01 na), which system has the higher axial resolution? how about for high na (approaching 1 na)? at what na do the two systems have approximately equal axial resolution?

A2 kg ball travellng to the right with a speed of 4 m/s collidees with a 5 kg ball traveling to the left with a speed of 3 m/s. take right to be the positive direction. what is the total momentum of the two balls before they collide? what is the total momentum of the two balls after they collide?

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.

Does work output exceed work input when a machine is used? a) yes, it does, as machines create energy. b) it depends on the type of machine used. c) no, it doesn’t, as machines are inefficient. d) no, it doesn’t, as machines cannot create energy.
