Answer:
Explanation:
The lift force will have a vertical component equal to the weight of the plane and a horizontal component sufficient to supply the needed centripetal accleration.
R = 8.01 mi = 12891 m
ω = 2π/T = 2π/(0.106(3600)) = 0.016465 rad/s
F = m√(g² + (ω²R)²)
F = 8930√(9.81² + (0.016465²(12891))²)
F = 8930√(9.81² + 3.49²)
F = 92,996.480...
F = 93.0 kN
θ = arctan(3.49/9.81) = 19.6°

Ralph is mowing the back yard with a push mower downward with a force of 20.0 N at an
angle of 30.0° to the horizontal. What are the horizontal and vertical components of the force
exerted by Ralph?
Answer:
Horizontal component = (10N) · sin (20°) = 3.42... N (rounded)
Vertical component = (10N) · cos (20°) = 9.39... N (rounded)

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.

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.

a ball thrown horizontally with the velocity of 20 m\s from a 20 m building .what is the time
Answer:2.02s
Explanation:
At the y component, the tract of the ball is free falling body. The initial velocity at y component is 0 m/s.
Height = 1/2 * g * t^2
20 = 1/2 * 9.8 * t^2
t = (20 * 2 / 9.8)^1/2, t = 2.02s
A sphere of radius r =34.5 cm and mass m = 1.80 kg starts from rest and rolls without slipping down a 30.0∘ incline that is 10.0 m long.
A.) calculate its translational speed when it reaches the bottom.
B.) Calculate its rotational speed when it reaches the bottom.
C.) what is the ratio of translational to rotational kinetic energy at the bottom?
Answer:
Explanation:
It depends on the construction of the sphere.
Let's ASSUME it is thin wall sphere with a moment of inertia (2/3)mR²
The Change in potential energy will equal the change in kinetic energy
mgh = ½mv² + ½Iω²
mgh = ½mv² + ½((2/3)mR²)(v/R)²
2gh = v² + 2/3v²
2gh = 5/3v²
v = √((6/5)gh)
v = √((6/5)(9.81)(10.0sin30.0))
A) v = 7.67 m/s
B) ω = 7.67/0.345 = 22.2 radians/s
C) ½mv² / ½Iω² = mv²/Iω² = mv²/((2/3)mR²)(v/R)² = 3/2
