2. what is the potential difference across a 100 m length of copper wire that has a diameter of 0.5 mm when it carries a current of 15 a? the resistivity of copper is 1.7 x 10-8 m.

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
