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
You multiply 3 by 120 to get $360 the answer is b. $360
Price is the value that is put into a product or service As a result of lots of calculations, research, understanding, and risk-taking. A pricing strategy, on the other hand, is the smart way a company makes in order to target and attract customers. There are four pricing strategies:
<span>1. </span>Premium pricing
<span>2. </span>Penetration pricing
<span>3. </span>Economy pricing and
<span>4. </span>Skimming pricing
Premium pricing and skimming strategy both use a high price while penetration pricing and economy pricing use a low price. <span>
<span>When Dillard company reduced the price of children’s Levis from $31.99 to $24.99, the used the penetration pricing. And when the manager of Jenney instructed his staff to do the same, he used the penetration pricing strategy also to attract customers. </span></span>
