Josefina and Raul were comparing how sound moves through various mediums and how charge moves through conducting wires. They performed experiments to find out if the factors that determine the speed of sound are the same as those that determine the flow in a circuit. What did they find? Describe two things that they found. For each, explain how the speed of sound and flow of current are affected

They found that difference occurs in the speed of both sound and charges occur due to the difference in the type of medium.

Sound and charges needs specific medium for faster movement i.e. sound moves faster in solid as compared to liquid and gas whereas charges moves faster and easily in gold due to lower resistance which is followed by copper. Sound can move from solid, liquid and gases whereas charges move only in solid metal in which free electrons are present. The speed of sound and flow of current are affected due to difference in the arrangement of atoms in solid, liquid and gas.

stupid i wont let you get a chance
