Answer:
Young's modulus for this alloy of nickel is 1.997×10^11 N/m^2
Explanation:
Young's modulus = stress/strain
Stress = Force (F)/Area (A)
F = mg = 59 kg × 9.8 m/s^2 = 578.2 N
A = πd^2/4 = 3.142 × (0.19/100)^2/4 = 2.836×10^-6 m^2
Stress = 578.2/2.836×10^-6 = 2.039×10^8 N/m^2
Strain = extension/length = 2.86×10^-3 m/2.8 m = 1.021×10^-3
Young's modulus = 2.039×10^8/1.021×10^-3 = 1.997×10^11 N/m^2
Answer:
She was known for her work on X-ray diffraction images of DNA, which led to the discovery of the DNA double helix for which Francis Crick, James Watson, and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962.
