C. Thick wire and cold temperature.
Explanation:
The resistance of a wire is given by: R = (ρL)/A
where ρ is the resistivity of the material, L is the length of the wire, A is the cross-sectional area of the wire.
From the formula, we see that the thicker the wire, the larger A, therefore the smaller the resistivity. so, a thick wire will have lower resistivity.
Moreover, the resistance of a wire increases with the temperature. In fact, high temperatures mean more motion of the atoms/electrons inside the wire, so more resistance to the flow of current through it. Therefore, colder temperature means lower resistance.
So, the correct option is thick wire and cold temperature.
V = f(wavelength)
22.0 = 0.0680 (wavelength)
wavelength = 323.52 m
Work is done. work=forcexdisplacement. the ice skater glides 2 meters (displacement), so yes.
Graph A so answer B also why isn’t answer a with graph A and B with graph B etc like that’s just confusing lol
