1.1.1. Define the human rights violation that you have chosen

sergij07 [2.7K]

The violation of human rights implies in situations of loss of freedom, violence and social inequality, being a social problem that must be actively fought.

<h3 /><h3>What are human rights?</h3>

They correspond to the rights inherent to all citizens, being superior to the rights of the State, in order to maintain the protection of individuals and society. For example, the right to:

Life
Freedom
Job
Freedom of expression

When a right is violated, such as gender-based violence, there is a violation of essential human rights, since every human being must be free and not suffer torture or any situation that implies their safety.

Therefore, it is essential that there is greater control and implementation of strict policies for the promotion and protection of human rights.

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>

How we use communication determines whether it will have positive or negative effects. this fact dispels what myth?

barxatty [35]

The myth that this statement dispels is that:

“Communication is inherently good.”

We have been communicating since we were born in this world. However not all people are good communicators which makes this myth dispellable. Just like money, communication can be used to deceive or intimidate people.

krok68 [10]

Answer:

The answer is "phonemes".

Explanation:

The phoneme seems to be a speech production entity, that has no sense by itself, although they are capable of writing phrases whenever they bring consonants combined.

It has different tones which distinguish among one and another word.
It may be difficult to count them since noises are made in various forms and combinations.
Via means of phonemes, readers are able to properly speak words and understand its concepts.
