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 answer is A.
Explanation:
According to the details given in the question on the two financial advisor's approach, the first advisor does not request a payment but a commission on the funds purchased with the inheritance money. The second advisor does request payment for the job and also a share on the assets managed with the inheritance money.
If Kirby wants to minimize the upfront expenses which can be described as the sum that is paid before a service or a job is done, then the first advisor is the better option. So the answer is A.
I hope this answer helps.
The correct answer is D. All of these.
Answer:
Increase by $37,100.
It will accept any time the price is above $43 with the condition it will not incur in additional fixed cost.
$63. is the sales price that generates 106,000 dollar of operating income
Explanation:
As the units will not inccur in any additional fixed cost we should check for the contribution margin this units will provide:
50 dollars - 43 dollar of variable cost = 7 dollars
5,300 saws x $7 = 37,100
The sales reveues will increase by that amount.
(5,300 x $43 dollars each in cost + 106,000 contribution )/5,300 = sales price
sales price = 63
