Correct Answer: C. 14\(ms^{-2}\)

Explanation

\(accl = \frac{\mathrm d V}{\mathrm d t}\)

\(V = 3t^{2} + 2t - 1 \therefore a = \frac{\mathrm d V}{\mathrm d t} = 6t + 2\)

\(a \text{(after 2 seconds)} = (6\times 2) + 2 = 12+2 = 14ms^{-2}\)

Correct Answer: B) Hexanedioic acid

Correct Answer: B. \(\frac{7x^{6}}{16}\)

Explanation

\((\frac{x}{2} - 1)^{8} = ^{8}C_{8}(\frac{x}{2})^{8}(-1)^{0} + ^{8}C_{7}(\frac{x}{2})^{7}(-1)^{1} + ^{8}C_{6}(\frac{x}{2})^{6}(-1)^{2} + ...\)

\(\text{The third term in the expansion =} ^{8}C_{6}(\frac{x}{2})^{6}(-1)^{2}\)

= \(\frac{8!}{6!2!}(\frac{x^{6}}{64})(1) \)

= \(28 \times \frac{x^{6}}{64} = \frac{7x^{6}}{16}\)
