Consider a steel guitar string of initial length L=1.00m and cross-sectional area A=0.500mm2. The Young's modulus of the steel is Y=2.0×1011N/m2. How far (ΔL) would such a string stretch under a tension of 1500 N?

Could someone . i have tried to solve myself but my calculation is off

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
