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:
$1,050,000
Explanation:
The computation of the net income is shown below:
Net income = Sales revenue × profit margin percentage
= $17,500,000 × 6%
= $1,050,000
To determine the net income we multiplied the sales revenues by its profit margin percentage so that the correct value could be arrived.
The process of combustion occurring without an open flame is called incomplete combustion
Answer: Elasticity of demand is 7.06
Explanation:
P1= $2,750
P2=$2,880
Q1=446,000
Q2=321,000
Elasticity = -0.76
Thus, elasticity of demand for laptops is 7.06. This means that laptops are highly price elastic as it is greater than 1.
Answer:
b. inputs and quantity of output
Explanation:
A production function is a relationship between inputs and the quantity of output. In other words, it is the entire production process that goes into creating a product. This includes the specific materials that need to be inputted into the process in order for the output to be exactly as needed in order for the product to come out as desired and the right quantity. Thus, creating a relationship between input and output
