Explanation

P = mv = 9.1 x 10\(^{31}\) x 4.2 x 10\(^{-7}\)

= 9.1 x 4.2 x 10\(^{-24}\) Kgms\(^{-1}\)

\(\lambda = \frac{h}{p} = \frac{6.6 \times 10^{-34}}{9.1 \times 4.2 \times 10^{-24}}\)

= 1.73 x 10\(^{-11}\)m

or

\(\lambda = \frac{h}{mv} = \frac{6.6 \times 10^{-34}}{9.1 \times 10^{-31} \times 4.2 \times 10^7}\) = 1.73 x 10\(^{-11}\)

Correct Answer: C. con—sti—TU—tion

Correct Answer: C. Rehoboam's foolishness

Correct Answer: D. K

Correct Answer: D. 1.8 years

Explanation

Mean (\(\bar{x}\)) = \(\frac{5 + 6 + 6 + 8 + 10}{5} \)

= \(\frac{35}{5} = 7\)

\(SD = \sqrt{\frac{\sum (x - \bar{x})^{2}}{n}}\)

= \(\sqrt{\frac{16}{5}} \)

= \(\sqrt{3.2}\)

\(\approxeq 1.8 years\)

Correct Answer: D. q \(\alpha \frac{1}{p}\)

Explanation

p \(\alpha \frac{I}{Q}\); p \(\frac{k}{q}\) (where k is constant)

q = \(\frac{k}{p}\)

q \(\alpha \frac{1}{p}\)

Correct Answer: B. get rid of the unbelievers
