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 answer is your last option: lower-level managers. Hope I helped! :)
Answer:
e) Adonis must pay $270,000 at maturity plus 20 interest payments of $14,850 each.
Explanation:
Based on this information,Adonis Corporation is issuing a coupon paying bond.
- The $286,827 that they receive is the market price/ market value of the bond.
- The duration of the bond = 10 years, however, since the coupons are paid semiannually, there will be 10*2 = 20 payments in total.
- Semi annual coupon payment; PMT = (11%/2) *270,000 = $14,850
- The $270,000 is the face value of the bond which must be repaid at the end of the life of this bond.
- <em>Therefore, Adonis must pay $270,000 at maturity plus 20 interest payments of $14,850 each.</em>
