Cevap

To determine the length of the aluminum wire, we need to use the formula for the volume of a cylinder: where:- is the volume of the cylinder,- is the radius of the cylinder,- is the height (or length) of the cylinder.Given:- The mass of the aluminum wire is grams.- The density of aluminum is grams per cubic centimeter ( ).- The diameter of the wire is inches.First, we need to convert the diameter from inches to centimeters. Since inch is equal to centimeters: Next, we find the radius by dividing the diameter by 2: Now, we can calculate the volume of the aluminum wire using the density formula: Now that we have the volume, we can solve for the length using the volume formula for a cylinder: Therefore, the length of the aluminum wire to be used for this experiment is approximately centimeters.
