A particular human hair has a Young's modulus of 3.18 × 109 N/m2 and a diameter of 152 μm. If a 2...
A particular human hair has a Young's modulus of 3.38×109 N/m2 and a diameter of 148 μm. If a 250 g object is suspended by the single strand of hair that is originally 20.0 cm long, by how much Δ? 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?(Al) would the aluminum stretch? If the strand of hair is modeled as a spring,...
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...
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 =...
pretty confused on how to solve this, if you could explain it
please
A particular human hair has a Young's modulus of 3.18 x 109 N/m2 and a diameter of 145 μm. If a 204 g object is suspended by the single strand of hair that is originally 19.5 cm long, by how much A L hair will the hair stretch? hair - If the same object were hung from an aluminum wire of the same dimensions as the hair,...
