An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?​

piece of copper having a rectangular cross-section of 15.2 mm x 19.1 mm is pulled in tension with 44,500 N force, producing only elastic deformation. Calculate the resulting strain? Shear modulus of elasticity of copper is 42 x 10⁹ N/m².

error = 62-60 = 2°

% = (2×100)/60 = 100/30 = 10/3 = 3.333%

i believe it's a.

i'm not sure on this one, most likely correct.
