Two wires with the same resistance have the same diameter but different lengths. If wire 1 has length L1 and wire 2 has length L2, how do L1 and L2 compare if wire 1 is made from copper and wire 2 is made from aluminum? The resistivity of copper is 1.7 × 10^–5 W•m and the resistivity of aluminum is 2.82 × 10^–5 W•m
a. L1 = 0.36 L2
c. L1 = 0.60 L2
b. L1 = 2.8 L2
d. L1 = 1.7 L2

You are in distant space, where there is no gravity. You hold two blocks of metal. They look and feel identical when touched, but you been informed that one is made of lightweight aluminum and the other of lead
Can you determine which one is lead without doing any kind of chemical analysis? A) You can determine this by dropping them; the lead ball will fall fastest. B) You can determine this by dropping them; the aluminum ball will fall fastest. C) You can determine this, by tapping each block with your finger; the one that accelerates the most is aluminum. D) You can determine this by giving each block a tap with your finger; the one that accelerates the most is the lead. E) The above methods will not work.
You are driving along a highway at 35.0 m/s when you hear the siren of a police car approaching you from behind and you perceive the frequency as 1310 Hz
