The maximum modulus of elasticity for a copper crystal is 195 GPa. What tensile stress is required along the corresponding crystallographic direction in order to increase the interatomic separation distance by 0.07 % ? Express your answer to three significant figures.

Which statement describes the appearance of a temperature-vs.-time graph? a horizontal line shows that the temperature increases at a constant rate over time. a vertical line shows that the temperature decreases at a constant rate over time. horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases. horizontal lines where the temperature increases are connected by upward-sloping lines where the temperature is constant for each phase.

Embryos of different species look very similar, which shows that the organisms share a ancestor.
