Which of the following can effect the resistance of a wire? I. the length of a wire
II. the thickness of a wire
III. the temperature of a wire

II and III
I and III
I and II
I, II, and III

II and III

Explanation:

Thicker wires have a larger cross-section that increases the surface area with which electrons can flow unimpeded.  The thicker the wire, therefore, the lower the resistance.

Thin wires have very high resistance the reason the thin tungsten in a bulb glows because it is heated from the high resistance of many electrons trying to pass through a very small cross-section.

the total length of the wires will affect the amount of resistance.

b.

the accuracy of the data.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
