Prenatal predictors of media use during infancy are understanding the behavior and attitude.

<h3>What do you understand by Infancy?</h3>

Infanthood is the time between birth and the beginning of language development in humans, which occurs one to two years later. Or, Infanthood is the early stage of anything or the time when a person is a baby, according to the definition. An example of a business in its early stages is one that just got off the ground last week. A one-month-old baby is an illustration of infancy. Humans learn to walk and communicate as toddlers as they develop their motor and language skills.

Answer: negative reinforcement by escape

Explanation: Negative reinforcement occurs when a disliked or aversive stimulus is prevented or altered or stopped. The scenario above describes negative reinforcement by escape which means that an aversive, unwanted or disliked event is removed after it has occurred. Escape is a negative reinforcement and occurs when the aversive stimulus has occurred before being removed. In the context above, Tom was only able to prevent his loss after it has occurred, meaning an escape negative reinforcement.

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>
