Hollywood studios get in trouble for a lack of diversity in their casting decisions. In order to remedy that, they create a computational model to find promising new actors. The computational model compares prospective actors to famous ones and chooses prospective actors that are the most similar to famous ones. What is a true statement about this computational model?
1. It will be effective and efficient at eliminating bias from casting decisions because computers are more objective than people.
2. Though it will choose from the applicants quicker than humans could, it will repeat the biases of the original casting decisions.
3. It is not a good idea to use computational models in the casting process as computers often deviate from the equations they're given. 4. While it would help eliminate bias from casting decisions, it is inefficient because it would be quicker for humans to choose the applicants.
Hollywood studios get in trouble for a lack of diversity in their casting decisions. The true statement about this computational model is that it will be effective and efficient at eliminating bais from casting.
Option 1 is correct.
The lack of diversity in Hollywood studios casting decisions results in the inability to select and choose the right actors for a specified role play.
The use of a computational model makes use of a computer program that studies and compares the prospective actors to famous ones and chooses prospective actors that are most similar to famous ones.
This is the best result to can be achieved and derived in making decisions in the diversity of casting because the computational model provides actors that are most effective and efficient thereby elimination the bias from casting decisions. This model is objective and it's not based on emotional decisions, unlike people.

What process is illustrated in the figure?
Answer: A
Explanation:
A driver spotted a police car and he braked from a speed of 100 km/h to a speed of 80 km/h during a displacement of 88 m at a constant acceleration? What is that acceleration, and how much time is required for the given decrease in speed?
Answer:
Explanation:
100 kph = 27.8 m/s
80 kph = 22.2 m/s
v² = u² + 2as
a = (v² - u²) / 2s
a = (22.2² - 27.8²) / (2(88))
a = -1.578282828...
a = -1.58 m/s²
t negative sign means the acceleration opposes the initial velocity.
t = Δv/a
t = (22.2 - 27.8) / -1.57828
t = 3.52 s

Making simplificafions, such as neglecting friction or not including all particles involved in an interaction, often makes computational models less accurate. Why are these simplifications made?
1. All initial values entered into the model are simply best guesses or estimates. By including more factors, more estimates are included and the inaccuracies compound as a result.
2. Simplifications actually tend to make models more accurate, not less accurate, because the simpler the model, the less chance there is for calculation error or other mistakes. 3. Computational models don't need to be accurate in order to be informative.
4. The effects of the simplifications are often relatively small, the computations may become too complex if all factors are included. or it isn't possible to know the initial values of all factors well enough to include them
Option 4. The effects of the simplifications are often relatively small, the computations may become too complex if all factors are included, or it isn’t possible to know the initial values of all factors well enough to include them
Computational models often make our derivations and complex studies get simplified. However these models ignores some factors which can only be determines practically.Hence, the statement in 4th option better indicates the need of simplifications.
What is computational model?A computational model is used to predict som complex structures or performing complex derivations and calculations using computer programmes and simulations.
For instance, there are various computational softwares such Gaussian to study the structural and electronic properties of molecules such as bond parameters, enthalpies etc. Similarly, the Hartree method for the calculation of energy levels can be performed using computational models.
These models simplifies and make more easier to understand a parameter or any structure or equation. However some factors which cannot included in these computations make a chance of inaccuracy in them.
In fact they cannot predicted by computations but can only be determined practically. But to make the study simpler adn near perfection we use these models without too much complex factors. Hence, option 4 is correct.

Robert is pushing a 2-kg box by 6 N. What is the acceleration of the box?
[tex]\\ \sf\longmapsto F=ma[/tex]
[tex]\\ \sf\longmapsto a=\dfrac{F}{m}[/tex]
[tex]\\ \sf\longmapsto a=\dfrac{6}{2}[/tex]
[tex]\\ \sf\longmapsto a=3m/s^2[/tex]
[tex]a = f \div m[/tex]
A= Acceleration=?F= Force = 6 N( Newton)M= Mass = 2kg[tex]a = 6 \div 3 \\ a = 3[/tex]
Hence, A is [tex]3m/s^2[/tex]A rock is held steady over a cliff and dropped. 1 seconds later, another rock is thrown straight down at a speed of 11.3 m/s, and hits the first rock. How far have the rocks dropped before they collide? How long is the first rock in the air before it gets hit by the second rock?
What is the displacement of the rocks when they collide? __________ (Hint: be careful of sign -- the rocks drop.)
The first rock is in the air for __________ before it is hit.
Answer:
4.27s
Explanation:
If "t" represents the time traveled from the time rock 2 is dropped until the collision, then the time traveled for rock 1 = t + 1. And, since rock #1 is dropped making its initial velocity = 0, then:
The distance rock 1 travels is
x = (0)(t + 1) + 1/2(-9.8)(t + 1)2 = -4.9(t2 + 2t + 1) = -4.9t2 - 9.8t - 4.9
The distance rock 2 travels
x = -11.3t + 1/2(-9.8)t2 = -11.3t - 4.9t2
For the distances must be equal when the rocks collide:
-4.9t2 - 9.8t - 4.9 = -11.3t - 4.9t2
-9.8t - 4.9 = -11.3t
-4.9 = -1.5t
t = 3.267 s
Now, the distance they traveled can be found by plugging the 3.267 s back into either equation:
x = -11.3(3.267) - 4.9(3.267)2 = -89.2 m or 89.2 m below where they began
The time the first rock was in the air is t + 1 = 3.267 + 1 = 4.267 s = 4.27 s
Let
First rocks time be x
Second rocks time be x+1
initial velocity=u=11.3m/s
Distance of both rocks be s1 and s2
[tex]\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2[/tex]
Now
[tex]\\ \sf\longmapsto s1=11.3x+5x^2[/tex]
[tex]\\ \sf\longmapsto s2=11.3(x+1)+5(x+1)^2[/tex]
As both collide then
[tex]\\ \sf\longmapsto s1=s2[/tex]
[tex]\\ \sf\longmapsto 11.3x+5x^2=11.3x+11.3+5(x+1)^2[/tex]
[tex]\\ \sf\longmapsto 5x^2=11.3+5x^2+10x+1[/tex]
[tex]\\ \sf\longmapsto 10x+12.3=0[/tex]
[tex]\\ \sf\longmapsto x=1.23s[/tex]
Displacement
[tex]\\ \sf\longmapsto 11.3(1.23)=13.8m[/tex]
