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

The principle of open opportunity in the marketplace means that anyone who wants to put up a business is welcome to do so. However, the success of his business rests entirely on how well it is received in the market.
Guaranteeing success to everyone in the marketplace is impossible. Competition is always present. Demand and supply can be affected by factors beyond human control.

<h3>What Is a Green-Field Investment?</h3>
A green-field (also "greenfield") investment is a type of foreign direct investment (FDI) in which a parent company creates a subsidiary in a different country, building its operations from the ground up. The strategy involves building everything the company needs from the ground (or green field) up. This can include all facets of the business, from plant construction to marketing and distribution channels.
