A particular human hair has a Young's modulus of 3.18 × 109 N/m2 and a diameter of 152 μm. If a 268 g object is suspended by the single strand of hair that is originally 16.0 cm long, by how much A L hair will the hair stretch? If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much Δ LAI would the aluminum stretch? If the strand of hair is...
A particular human hair has a Young's modulus of 3.80 x 10 N/m² and a diameter of 150 um. If a 234 g object is suspended by the single strand of hair that is originally 15.0 cm long, by how much AL hair will the hair stretch? AL hair = m If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much ALA would the aluminum stretch? ALAI = ALA =...
A particular human hair has a Young's modulus of 3.54 × 10 9 N/m 2 and a diameter of 143 μm. If a 215 g object is suspended by the single strand of hair that is originally 19.0 cm long, by how much Δ L hair will the hair stretch? Δ L hair = m If the same object were hung from an aluminum wire of the same dimensions as the hair, by how much Δ L Al would the...
You are trying to figure out how fast your BB gun can shoot. So you set up a block-spring system. By firing the BB into the block, the spring gets compressed. Specifics: Mass of BB = 8 grams, mass of block = 4.0 kg, spring compression = 3.7 cm, spring constant = 2500 N/m. Calculate the speed of the BB. 1 440 m/s 2 520 m/s 3 500 m/s 4 460 m/s 5 480 m/s Question 14 -- /5 What...
