?

I have a device which works on an AC adapter with 5V,1.5 A DC output. I want to use the same adapter to power another module as well which has a power consumption of 119 mA @ 5V DC max. Will it be possible to do so? If yes, what kind of current regulatory circuit will i require?

Is it possible to have a Server PC running a MS Excel Sheet to which several Thin Clients will be connected via TCP/IP having Barcode Scanners? The scanner's should dump their Data in the MS Excel Sheet in a First Come First Server basis?

And, is there any other alternatives to achieve the above requirement?

Barcode Scanners have USB Output.

If light (EM wave) was concentrated in small packets or Photons, having some definite Kinetic Energy(w/ kinetic mass), then it should also have momentum. If it has momentum, those photons should also possess inertia, then why does not a beam of light, produce mechanical force on the object it falls? like for instance, turn a turbine or paddle wheel when it'll fall on one half of it? Same way as cathode rays turn a paddle wheel. Why is light considered to be EMw to satisfy certain things and Corpuscular to satisfy otherwise.. :/ There must be something that is intermediate to both theories or something that is way different but explains all the phenomenon of light. Viz, Reflection, refraction, diffraction, polarization, photo-electric effect, Compton effect etc.
