Answer:
a. radius = 0.0006m = 0.6mm and length =0.393m = 393mm
b. frequency =377.86Hz
Explanation:
Given:
mass of steel= 4g = 0.004kg
density of steel = 7890kg/m3
tensile stress of steel 7.0x10⁸
tension load =900N
from the density, we will calculate for the Volume of the steel string
density = mass/volume
volume = mass/density = 0.004/7890 = 5.07 x 10⁻⁷ m³
from the tensile stress will can get the maximum base Area of the string ,
tensile stress = load/area =
7x10⁸ = 900/A
A = 900/7x10⁸ = 1.29x10⁻⁶ m²
Area = πr²
area/pi = 4.105x10-7
radius = 0.0006m = 0.6mm
volume = Area x length
length = vol/area =(5.07 x 10⁻⁷ m³)/1.29x10⁻⁶ m² = 0.393m
b. the highest possible frequency is given by:
F = 
where T= tension, m=mass, L=length
F = 
= 297.04/0.786
frequency =377.86Hz
Answer:
The difference in human capital explains $7,863 of the income per worker gap while the difference in physical capital explains $20,181 of the income per worker gap.
Explanation:
Human capital refers to the skills, knowledge, and efforts of the people in producing goods and services. It is also known simply as labor. Physical capital refers to the "man-made" goods that assist in production, including machinery, equipment, and technological items such as computers.
In the given scenario, the income per worker in the United States is $82,359 - $54,315 = $28,044 more than the income per worker in South Korea. This is explained by differences in both the level of technology (i.e. physical capital) and the capability of workers (i.e. human capital).
We are informed that the income per worker in South Korea would be $74,496 if it had the same level of technology as the United States. This means that $74,496 - $54,315 = $20,181 of the income per worker gap between the two countries is explained by differences in physical capital. Hence the remaining difference of $28,044 - $20,181 = $7,863 is explained by differences in human capital between the two countries.
Answer:
The correct answer is letter "C": average person in the economy.
Explanation:
The Gross Domestic Product (GDP) measures the level of output of a country given a certain period -by quarter and year, usually. It considers <em>government expenditures, private investments, consumer spending, </em>and <em>net exports </em>(exports minus imports).
The GDP per capita represents the GDP per person and is calculated by dividing the GDP by the population of a country. GDP per capita represents an approximate of the expenses of an individual. Smaller richer countries such as Luxembourg or Switzerland tend to have higher GDP per capita.
Answer:
d. an increase in the quantity of bicycles demanded.
Explanation:
For this question, the law of demand applies.
According to the law of demand, when the price of the good increases the quantity demanded of that good would be decreased keeping other things constant and when the price of the good decreases the quantity demanded of that good would be increased keeping other things constant.
It reflects the inverse relationship between the price and the quantity demanded of the good.
Answer: Job order costing
Explanation:
The costing of work orders or job costing refers to the method for distributing and collecting production costs to a specific production unit. The costing method for job orders is implemented when the different items generated vary significantly from one another and each one has a substantial cost.
The job cost documents also perform as the conglomerate ledger for the expense of the job-in-process stock, the stock of finished products, and the charge of selling products to the supplier. Because there is a considerable difference in the produced goods, a separate department order cost report for each individual item is required for the job order pricing system.
