Answer:
angular acceleration of the disk ∝ = K
explanation:
Given that; Angular velocity function given by ω = Kt + L Angular acceleration of the disk at t=T is = ? Now, Angular velocity; ω = Kt + LAngular acceleration is;∝ = dω / dt= ( Kt + L )At t = T∝ = K Because ∝ is not dependent on t Therefore angular acceleration of the disk ∝ = K
The american association of individual investors (aaii) conducts a weekly survey of its members to measure the percent who are bullish, bearish, and neutral on the stock market for the next six months. For the week ending march , , the survey results showed bullish, neutral, and bearish. Assume these results are based on a sample of aaii members
The information about the American association of individual investors shows that the test statistic is -1.89.
How to calculate the test statistic?From the complete information, it was stated that the survey results showed 33.2% bullish, 39.6% neutral, and 27.2% bearish and there were 300 members.
Therefore, the test statistic will be:
= 0.332 - 0.385 / (✓0.385 × ✓0.615 / ✓300)
= -1.89
In conclusion, the test statistic is -1.89.

The law of sine or the sine law expresses the ratio of the side length of a triangle to the sine of the opposite angle, which exists identical for all three sides. It stands also known as the sine rule.
What is an angle?
An angle exists the figure formed by two rays, named the sides of the angle, sharing a common endpoint, named the vertex of the angle. Angles formed by two rays lie in the plane that includes the rays. Angles exist also formed by the intersection of two planes. These exist named dihedral angles.
The law of sine or the sine law expresses the ratio of the side length of a triangle to the sine of the opposite angle, which exists identical for all three sides. It stands also known as the sine rule.

Do you think evil exists? Is there an ultimate cause of evil? If there is an ultimate cause of the good (for example, God) and an ultimate cause of evil (for example, the Devil), which ultimate cause is greater? How do you know? If God exists and God is good, then why does God allow evil in the world? Can God design a world without suffering? If God is dead or does not exist, does this mean that evil will take over the world? Can good exist without God? Are humans free to do evil acts if they have free will? If yes, then is giving humans free will in fact an evil act? Can a person be evil while going good deeds?
Answer:
Evil people don't exist, but evil actions do.
Explanation:
No one can be born completely evil, but they could have done evil things. There isn't one cause of evil, rather, there are many and they vary. An example of one could be massacre ten people because those people killed their child, or friend, or relative of some sort. While it isn't right, there is usually motives. Someone who has hunger for human flesh will kill humans to eat them. It also isn't right, but the hunger is the motive, not the main drive of the person. I don't think God and the Devil exist, but if they did, God could not create a world without suffering. It is impossible to watch everything at once and if God helped us too much, we'd be helpless to defend ourselves and we could not function or advance without God's help. Good can exist without God, because there are always good people out there. Humans are free to do evil acts if they have free will, but that doesn't mean everyone would do evil acts. Giving humans free will is not an evil act, it's like giving lifeless puppets life and watching them. Refusing humans free will is also an evil act, it is basically like slavery. Yes, a person could be evil while doing good deeds because like I said, no one is completely evil.

A bicycle has wheels that are 60 cm in diameter. What is the angular speed of these wheels when it is moving at 4. 0 m/s?
Answer:
ω = 13.33 rad/sExplanation:
Applying,
v = ωr......................... Equation 1
Where v = linear speed, ω = angular speed and r = radius.
Note that,
r = d/2................. Equation 2
Where d = diameter of the wheel.
Substitute equation 2 into equation 1
v = ωd/2............... Equation 3
make ω the subject of the equation
ω = 2v/d................ Equation 4
Given: v = 4 m/s, d = 60 cm = 0.6 m
Substitute these values into equation 4
ω = 2(4)/0.6
ω = 13.33 rad/s

How career and study choices are influenced by availability of finances/affordability
There are several elements that might impact a person's profession decision. This decision-making process begins when high school graduates decide on the degree they want to pursue while keeping their budget in mind. A college degree is a valuable commodity that many young folks want to get, but it is also growing increasingly expensive. Many students choose a more cheap and practical degree over what they actually want to study because of economic considerations. In truth, college affordability is a catastrophe that the United States is currently confronting. According to the College Board, students at public universities spend more than $20,000 on tuition and room and board alone during the course of a four-year degree. As a result of the crisis, many students are obliged to pursue less costly occupations, which means they must take less expensive degree programs. The cost of receiving a higher education might impact an individual's study choices and, as a result, his or her future employment choices.

Since there are four C-H bonds present in CH4, the bond energy of CH4 is 1652 kJ/mol.
What is bond energy?The term bond energy refers to the energy required to break the bond between two atoms. We have to note that the bond energy of one mole of a molecule depends on the number of individual bonds in the molecule.
For CH4, we know that there are four C-H bonds present. Each C-H bond has a bond energy of about 413 kJ/mol. As such, the bond energy of CH4 is 4( 413 kJ/mol) = 1652 kJ/mol.

What do you mean by Trigonometric functions?Trigonometric functions may be characterized as those functions that are actual and tangible in all respective forms. They simply function as the angle of a triangle. The three basic and most fundamental trigonometry functions may include Sine, Cosine, and Tangent.
According to the context of this question,
We have a right-angled triangle and require to find the angle L. This is found with help of the Tangent of an angle in a right-angled triangle. It is the respective ratio of the opposite side to the adjacent side.
The height of a pole = 9.5 feet.
The height of the shadow which is formed = 29 feet.
tan L = JK / LK
tan L = 9.5 / 29
L = tan⁻¹ (9.5 / 29)
L = 0.31657 radians ≅ 0.32 radians.
