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: b.the principles of management are much the same at large and small firms.
Explanation:
Quinn will find that Management Principles do not discriminate against different sizes of firms and that the principles that work in one size can work across ALL sizes.
She will find that the same Principles that helped her in her big NGO will help her JUST AS WELL in this small but pioneering business.
According to the Phillips curve analysis, disinflation happens when the actual rate of inflation is initially lower than the expected rate, temporarily raising the unemployment rate. However, as nominal wages decline, the unemployment rate will fall to its natural level and the actual and expected rates of inflation will balance out.
Disinflation refers to occurrences where the inflation rate has temporarily slowed and is used to indicate situations where it has only slightly decreased. Disinflation refers to the rate of change in the rate of inflation, as opposed to inflation and deflation, which talk about the direction of prices.
