owners of the professional National League adopted a “gentleman’s agreement” to keep blacks out. Subsequent African.

Suppose you find a rock that contains 10 micrograms of radioactive potassium-40, which has a half-life of 1.25 billion years. By
attashe74 [19]

Answer:

The rock is 3.75 billion years ago.

Explanation:

Given that:

Half life = 1.25 billion years

1 billion years = 10⁹ years

So,

Half life = 1.25 × 10⁹ years

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

k=\frac {ln\ 2}{t_{1/2}}

k=\frac {ln\ 2}{1.25\times 10^9}\ year^{-1}

The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹

Initial amount [A₀] = 80 micrograms

Final amount [A_t] = 10 micrograms

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

So,  

10=80\times e^{-5.5452\times 10^{-10}\times t}

80e^{-5.5452\times \:10^{-10}x}=10

\frac{80e^{-5.5452\times \:10^{-10}x}}{80}=\frac{10}{80}

\ln \left(e^{-5.5452\times \:10^{-10}x}\right)=\ln \left(\frac{1}{8}\right)

x=\frac{10^{10}\times \:3\ln \left(2\right)}{5.5452}=3.75\times 10^9

So,

<u>The rock is 3.75 billion years ago.</u>

Black_prince [1.1K]

Answer:

a decrease in her intrinsic motivation.

Explanation:

According to self-determination theory, the impact of this reward system is likely to be a <em>decrease in her intrinsic motivation of reading books and writing short stories</em>. The self-determination theory states that it is vital for psychological well-being to be in control of one´s destiny. So, the impact of this reward can only be detrimental to Nikki's intrinsic motivation for reading books and writing short stories. Being extrinsically rewarded makes intrinsic motivation decrease.

Which of the following groups was NOT one of Southern Africa’s early settlers?
makvit [3.9K]
<span>he history of South Africa is characterized by racial and political violence, territorial conflict, wars of conquest, and inter-ethnic rivalry. The aboriginal Khoi and San lived in the region for millennia. Most of the rest of the population trace their history to later immigration. Africans (also referred to as Bantu) in South Africa are descendants of migrants from central Africa, who first entered southern Africa about 2000 years ago. White South Africans are descendants of later European settlers, mainly from the Netherlands, Germany, France and Britain. The large population of Coloureds, as they were officially classified, are descended at least in part from all of these groups, as well as from slaves imported from Madagascar, East Africa and the then Dutch East Indies. The discoveries of diamonds and gold in the 19th Century had a profound effect on the fortunes of the region, propelling it onto the world stage and introducing a shift away from an exclusively agrarian-based economy towards industrialization and the development of urban infrastructure. The discoveries also led to new conflicts including open warfare between the Boer settlers and imperial Britain. South Africa was under an official system of racial segregation and white minority rule from 1948 known as Apartheid, until its first egalitarian elections on 27 April 1994, when the African National Congress came to power and dominated the politics of the country in alliance with the South African Communist Party and the Congress of South African Trade Unions.</span><span />
