You apply a force of magnitude F1 to one end of a wire and another force F in the opposite direction to the other end of the wire. The cross-sectional area of the wire is 8.00 mm2. You measure the fractional change in the length of the wire, Al/lo. for several values of F. When you plot your data with Al/lo on the vertical axis and F (in units of N) on the horizontal axis, the Part A What is the value of Young's modulus for this wire? data lie close to a line that has slope 8.0 x 10-7N-1 Express your answer with the appropriate units.

A scanning electron micrograph of xylem vessels in a corn root shows the vessels magnified by a factor of 608. In the micrograph the xylem vessel is 5.60 cm in diameter. What is the diameter of the vessel itself, answer in cm? and By what factor has the cross-sectional area of the vessel been increased in the micrograph?

The mass of the cube is 12 grams. Calculate the density of the cube using the length measurement values read from the micrometer. Length: 1.05 mm Width: 1.25 mm Height: 0.95 mm width length A. 8.2 g/cm3 B. 13.4 g/cm? C. 9.6 g/cm3 D. 8.4 g/cm3 E. 10.1 g/cm3 height

Gold, which has a density of 19.32 g/cm3, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber. (a) If a sample of gold with a mass of 4.041 g, is pressed into a leaf of 1.423 μm thickness, what is the area of the leaf? (b) If, instead, the gold is drawn out into a cylindrical fiber of radius 2.900 μm, what is the length of the fiber?
