Let g be the function given by g(x)=x2ekx, where k is a constant. For what value of k does g have a critical point at x=23?.

Answers

Answer 1

It looks like we have

[tex]g(x) = x^2 e^{kx}[/tex]

If x = 23 is a critical point of g(x), then

[tex]g'(x) = 2x e^{kx} + kx^2 e^{kx} = (kx^2 + 2x) e^{kx}[/tex]

[tex]\implies g'(23) = (23^2k + 46) e^{23k} = 0[/tex]

[tex]e^{23k}[/tex] is positive for all k, so we're left with

23² k + 46 = 0

23² k = -46

k = -46/23²

k = -2/23

what is the effective nuclear charge for a 2nd row electron in sulfur?

Answers

Sulfur valence electrons have an effective nuclear charge of +6.

What are effective nuclear charge?

Effective nuclear charge is defined as the true positive nuclear charge that an electron in a multi-electron atom experiences. Electrons and protons are the two elements that cause the effective nuclear charge to rise. Zeff = Z - S is the actual nuclear charge.

A sulfur second row electron's effective nuclear charge is 14. Since sulfur contains 16 protons, or 16 atomic numbers, we know that there are 2 electrons in its first shell or orbit, which due to its rapid speed creates a shielding effect.

Thus, sulfur valence electrons have an effective nuclear charge of +6.

in the late 1800s, china experienced an internal crisis when emperor guang xu launched massive reforms throughout the nation. why were these reforms opposed, thus creating an internal crisis in china?

Answers

Note that in the late 1800s, China experienced an internal crisis when emperor Guang Xu launched massive reforms throughout the nation. It is to be noted that these reforms were opposed and hence caused internal crises because: "Some people felt reforms would ruin the Chinese economy." (Option A)

How did the crises erupt?

Among many persons, Prince Duan, a late Qing dynasty stateman, was the most vocal in his opposition to the changes. Prince Duan had resisted the changes because he felt a foreign scheme was at work, with many Western concepts, including military tactics, education, and political methods, being proposed for implementation, and he was threatening to deport all foreigners from China.

As a result, they executed and imprisoned all reform supporters and held King Guang Xu under house arrest until his death.

According to some historians, Emperor Guang Xu was the first Chinese ruler to pursue modernizing reforms and capitalism. Imperial power in the Qing dynasty reached a low under Guangxu, and he was the first Qing emperor to be imprisoned during his own reign.
