A metal has a BCC crystal structure, and its unit cell parameter (a) is 0.2881 nm. The density of the metal is 7.141 gram/cm?. Calculate the atomic mass of the metal. Answer: Assertion: Slippage along slip planes are difficult in ceramics. Reason: Too much energy is needed to move one anion past another anion. Which of the following is correct? 6 7 Select one: Both assertion and reason are true and the reason is a correct explanation of the assertion. on 100 8 The assertion is false but the reason is a true statement. Both the assertion and reason are false statements. 91 The assertion is true but the reason is a false statement. Fin Both assertion and reason are true but the reason is not a true explanation of the assertion
