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 and Explanation:
The computation is shown below:
For account receivable turnover ratio
Accounts Receivable Turnover is
= Sales ÷ Average Receivables
Beginning Accounts Receivable $21,400
Add: Sales $105,300
Less: Cash Receipts $81,300
Ending Accounts Receivable $45,400
Now
Accounts Receivable Turnover is
= $105,300 ÷ ($21,400 + $45,400) ÷ 2
= 3.15 times
Now days to sell is
= 365 ÷ 3.15 times
=116 days

Answer:
Degree of Operating Leverage = 1.34
The Operating cash flow increases by 12%
The new operating cash flow is $290200
Explanation:
% change in Operating Cash Flow = Degree of Operating Leverage * % change in sales
There is need to calculate Degree of operating leverage first. Degree of operating leverage = Contribution / EBIT
Where Contribution = OCF + Fixed costs / OCF
Fixed costs= Total costs - variable costs = 300000 - 215000
Fixed Cost= 85000
Degree of operating leverage = (250000 + 85000) / 250000
DOL= 1.34
% change in OCF = DOL * % change in sales
% change in sales = (56000 - 50000) / 50000 = 12%
% change in OCF = 1.34 * 12% = 16.08%
New OCF = 250000 * (1+16.08%)
=$250000 * (1 + 0.1608)
=$250000(1.1608)
= $290200
Answer:
Must be exactly 8,000 people per hour.
Explanation:
Flow rate or throughput is the rate at which customers, goods, or services flow though a business process. It is usually measured as an average number of units that pass through a process per unit time.
In this scenario the people that entered the NASCAR venue were 8,000 people per hour.
So when people are coming out of the NASCAR venue average rate of flow out must be 8,000 people per hour.
The rate of units entering a business process must be equal to rate of units coming out per unit time.
