Answer:
The similarity between the Great Depression and America’s housing and economic crisis that began in 2008 is:
They were business investments
According to the events which occurred during the Great Depression, there was a reduction of over half in the industrial production as there was a great financial loss based on the money invested in the industry.
As a result of this, we can see that although the housing and economic crisis and the Great Depression were similar because they were business investments, the effects of the Great Depression was greater.
Explanation:
The pulley in the figure (figure 1) has radius r and a moment of inertia i. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The coefficient of kinetic friction between block a and the tabletop is μk. The system is released from rest, and block b descends. Block a has mass ma and block b has mass mb
The speed of block B in terms of the distance (d) it has descended is [tex]V=\frac{2gd(m_B-\mu_k m_A)}{m_A \;+\; m_B \;+\;\frac{I}{r^2}}[/tex]
How to determine the speed.In order to determine the speed of block B in terms of the distance (d) it has descended, we would apply the work-energy theorem as follows:
[tex]Work=\Delta KE=KE_f-KE_i[/tex]
The work done due to gravity is given by:
[tex]W_g=(m_B)gd[/tex]
The work done due to friction is given by:
[tex]W_f=-\mu_k (m_A)gd[/tex]
The angular velocity of pulley is given by:
[tex]\omega = \frac{V}{r}[/tex]
Applying the work-energy theorem, we have:
[tex]W_g+W_f= KE_f-KE_i\\\\(m_B)gd-\mu_k (m_A)gd=\frac{1}{2} m_A V^2+\frac{1}{2} m_B V^2+\frac{1}{2} I\omega^2-0\\\\gd(m_B-\mu_k m_A)=m_A V^2+ m_B V^2+\frac{1}{2} I(\frac{V}{r} )^2\\\\2gd(m_B-\mu_k m_A)=(m_A + m_B +\frac{I}{r^2} )V\\\\V=\frac{2gd(m_B-\mu_k m_A)}{m_A \;+\; m_B \;+\;\frac{I}{r^2}}[/tex]

A car travels 20. Meters east in 1. 0 second. The displacement of the car at the end of this 1. 0-second interval is
Answer:
Displacement is the word we use for the distance covered so in this case when a car travels 20 meters east in 1 second, at the end of that 1-second interval a car travels a distance of 20 meters.
And the distance covered is the displacement, so it means that displacement of the car after 1 second is 20 meters east.
If δdef and δmno are two triangles such that de ≅mn and ef ≅ no, which of the following would be sufficient to prove the triangles are congruent?
The information that would be sufficient to prove that both triangles are congruent by the SAS congruence theorem is: ∠E ≅ ∠N.
What is the Side-angle-side Congruence Theorem (SAS)?When two sides and one included angle in a triangle is congruent to two corresponding sides and an included angle in another triangle, both triangles are congruent to each other by the SAS congruence theorem.
Thus:
ΔDEF and ΔMNO have:
Two pairs of congruent sides: DE ≅ MN and EF ≅ NO.
Therefore, the information that would be sufficient to prove that both triangles are congruent by the SAS congruence theorem is: ∠E ≅ ∠N.

One beaker contains pure water and the other beaker contains pure methanol at the same temperature. Which liquid has the higher surface tension and viscosity?
The water has a higher viscosity and surface tension compared to the methanol.
What is Surface Tension?Surface tension can be defined as the force that acts on the surface of a liquid to give it am elastic skin that is stretched.
Thus, because of the strong intermolecular hydrogen bonding in water and it's high melting and boiling point than methanol, the surface tension and viscosity of water is higher than that of methanol.

You want to measure the height of an antenna on the top of a 125 foot building
In a 125-ft tall building, if you measure the angle of elevation to the top of the building to be 68° and the angle of elevation to the top of the antenna to be 71°, the height of the antenna is 21.7 ft.
What is the tangent of an angle?In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Step 1: Calculate the distance to the builiding (x).We will use the tangent of 68°, being the height of the building (h1 = 125 ft) the opposite side.
tan 68° = 125 ft / x
x = 50.5 ft
Step 2: Calculate the height of the building and the antenna (h2).We will use the tangent of 71°, being the distance to the building (x = 50.5 ft) the adjacent side.
tan 71° = h2 / 50.5 ft
h2 = 146.7 ft
Step 3: Calculate the height of the antenna.h2 - h1 = 146.7 ft - 125 ft = 21.7 ft
In a 125-ft tall building, if you measure the angle of elevation to the top of the building to be 68° and the angle of elevation to the top of the antenna to be 71°, the height of the antenna is 21.7 ft.
The complete question is:
You want to measure the height of an antenna on the top of a 125 foot building. From a point in front of the building, you measure the angle of elevation to the top of the building to be 68° and the angle of elevation to the top of the antenna to be 71°. How tall is the antenna, to the nearest tenth of a foot?

Harmony is currently producing 100 units of a necessary component part by incurring p60,000 in direct materials, p12,500 in direct labor, p22,500 in variable overhead, and p15,000 in fixed overhead. Harmony can purchase the component externally for p95,000 and only p2,500 of fixed manufacturing costs cannot be avoided (the rest are avoidable). How much savings will harmony realize in buying instead of making the component?
By taking the difference between the two costs, we conclude that buying instead of making the component, she saves $12,500
How much will she save?If she makes the components, the cost is:
$60,000 + $12,500 + $22,500 + $15,000 = $110,000
On the other hand, if she buys the components, the cost will be:
$95,000 + $2,500 = $97,500
To find how much did she saves, we need to find the difference between the two costs. That is just:
$110,000 - $97,500 = $12,500
This means that by buying instead of making the component, she saves $12,500

A population has a mean of and a standard deviation of . suppose a simple random sample of size is selected and is used to estimate . use z-table. a. what is the probability that the sample mean will be within of the population mean (to decimals)? b. what is the probability that the sample mean will be within of the population mean (to decimals)?
The probability of the sample mean in each of the given options are respectively; 0.8884 and 0.9934
What is the Probability?We are given from online complete question;
Mean; µ = 300
Standard deviation; σ = 70
Sample size; n = 125
A) For the sample to be within 8 units of the population mean, we would have sample values of 292 and 308. Thus, the expression is;
P(292 < x < 308).
z-score here is;
z = (292 - 300)/(70/√125) or z = (308 - 300)/(70/√125)
z = -1.28 or 1.28
From online p-value from z-score calculator, the p-value is 0.8884.
B) For the probability of the sample mean to be within 17 units of the population mean, we need to find the values from 283 to 317. We want to find P(283 < x < 317).
The z-scores here are;
z = (283 - 300)/(70/√125) or z = (317 - 300)/(70/√125)
z = -2.72 or 2.72
From online p-value from z-score calculator, the p-value is 0.9934

How vocation stress may negatively affect your family
Explanation:
Vocational stress refers to the stress caused because of one’s professional settings. It can be caused because of a number of reasons, like the fear of losing one’s job, working overtime, not getting credit for one’s efforts, being pushed to meet unrealistic targets, being blamed unfairly, not getting along with the boss or colleagues, or being forced to compromise with one’s honesty. In any case, vocational stress causes feelings of fear and anxiety, which greatly affects family life.
A high degree of stress or anxiety makes one irritable and impatient. The person becomes unpredictable and easily loses his/her temper with family members. Tantrums become common and the rest of the family start avoiding the individual. A disconnect starts setting in, pushing him/her further into depression. This leads to a lack of confidence and eventually with growing frequency of arguments, family life does not remain peaceful.
