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
Where, k is rate constant
So,
The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount ![[A_t]](https://tex.z-dn.net/?f=%5BA_t%5D)
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,
So,
<u>The rock is 3.75 billion years ago.</u>

Aside from the milestones, Louis Armstrong achieved as a jazz soloist which made him the most influential musician in the music's history, his success can be mainly attributed to the "engaging" personality he has. He was idolised by his jazz fans mainly because he wants to be seen as more of an entertainer.
Answer:
a. Distance and displacement
Distance :-)
- <em>Distance is the length of a path between two points.</em>
- <em>Distance is a scalar quantity.</em>
- <em>Distance is denoted by “d”.</em>
Displacement :-)
- <em>Displacement is the shortest distance between two points.</em>
- <em>Displacement is a vector quantity.</em>
- <em>Displacement is denoted by “s”.</em>
b. Speed and velocity
Speed :-)
- <em>Speed is the time rate at which an object is moving along a path.</em>
- <em>Speed is a scalar quantity.</em>
- <em>Formula is s= d/t.</em>
<em>Velocity :-)</em>
- <em>Velocity is the rate and direction of an object's movement.</em>
- <em>Velocity </em>is a vector quantity.
- <em>Formula is d= s/t.</em>
c. Work and power
Work :-)
- <em>Work is defined as the process of energy transfer to the motion of an object through the application of force.</em>
- <em>Work is a scalar quantity. </em>
- <em>The SI unit of work is Joule (J).</em>
Power :-)
- <em>Power is defined as the amount of energy transferred in unit time. </em>
- <em>Power is a scalar quantity.</em>
- <em>The SI unit of power is Watt (W).</em>

1- To me, psychology means the discipline that tries to explain human behavior and its complexities.
2- That is easy to major in psychology but one has to read a lot to do so. That being insightful is needed if you want to pursue a career in this field.
3- Not really. Usually, in Tv and movies psychologist are portraited as Psychoanalysts or therapists. In real life, the field of the psychologist is broader and not everything is about psychotherapy.
4- That is a magical solution, that the therapists only listen to your problems and they magically disappear, that is easy, that is magical, that hypnosis work 100% of the time. That "shrinks" are crazier than their patients, that having a mental illness means that you are an aggressive person, and so on. Media either glamorizes or stigmatizes the figure of the psychotherapist.
