What happens to a circuit's resistance (R), voltage (V), and current (1) when you change the thickness of the wire in the circuit?
A. Vand I will also change, but R will remain constant.
B. R, V, and I will all remain constant.
C. Rand I will also change, but V will remain constant.
D. Rand V will also change, but I will remain constant.

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b.compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength
