Neurological disordersThe neurological disorders are does diseases that affect the nervous system of an individual.
Examples of the neurological disorder include:
Alzheimer's disease: This occurs in individuals that have low levels of the neurotransmitter, acetylcholine. The acetylcholine activates muscles and help in short-term memory, and learning.Parkinson's disease: This occurs in individuals that have low levels of the neurotransmitter, dopamine. Dopamine plays a role in sending messages to the part of the brain that controls movement and coordination.Therefore, Acetylcholine is to Alzheimer's disease dopamine as is to Parkinson's disease.

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?
Answers
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

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.
Answers
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.

The weight of an object is 180 N at a distance of 150 km above a planet's center. What is the weight of the object when it moves 450 km above the center of the planet?
Answers
By using Newton law of gravitation, the weight of the object when it moves 450 km above the center of the planet is 20N
Given that the weight of an object is 180 N at a distance of 150 km above a planet's center.
F = GMm/[tex]r^{2}[/tex]
F = mg = 180N
r = 150
When it moves 450 km above the center of the planet, G, M and m will be constant. only r will vary.
180 = GMm/[tex]150^{2}[/tex]
Make GMm the subject of the formula
GMm = 180 x 22500
GMm = 4050000
As it moves 450 km above the center of the planet, Its weight will be
F = GMm/[tex]r^{2}[/tex]
Substitute all the values and parameters
F = 4050000/[tex]450^{2}[/tex]
F = 20 N
Therefore, the weight of the object When it moves 450 km above the center of the planet is 20 Newtons

If the strength of the sun's magnetic field decreased from its current level, why would the temperature of sunspots increase?
Answers
Magnetic field lines emerge from one sunspot and re-enter at the other spot. Also, there are more sunspots during periods of increased magnetic activity. At ...
The temperature of sunspots increases because magnetic field lines emerge from one sunspot and reappear in another. During periods of increased magnetic activity, there are also more sunspots.
What is the sun's magnetic field?The magnetic field of the sun has two poles, similar to a bar magnet. Every 11 years, at the peak of the solar activity cycle, the poles flip.
The magnetic field is carried away from the sun's surface and through the solar system by a solar wind made up of charged particles. The sun is more like a fluid than a solid ball.
Thus, the magnetic field lines emerge from one sunspot and reappear in another. During periods of increased magnetic activity, there are also more sunspots.

A substance with a pH value of 2.3 would be classified as a strong acid. Option A is correct.
What is ph value?pH stands for "potential hydrogen," and it is a measure of the acidity or basicity (alkalinity) of a solution. The pH scale ranges from 0 to 14, with 7 being neutral (neither acidic nor basic). Solutions with a pH less than 7 are considered acidic, and solutions with a pH greater than 7 are considered basic.
