Rs Vin Vg-Vin -R8 Solving for the power source impedance, we get:
Rg V:-Vin Vin .Rs
Depending on the circuit design, the impact of the device impedance in this scenario may be very large, or it may be negligible. Using V, of 8 volts, what would v.. be if R = OIR ? Or what if R. = 100R ? Can you make a general statement?

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.

a self-report inventory personality assessment is not very reliable for a psychological test because a patient doing the assessment may exaggerate or under-report in the answers. also, people will tend to be high on desirable behaviors and low on undesirable things.
