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:
$250 is the answer
Explanation:
As we want to calculate here the net income which could be found from the following formula:
Net Income or Profit = Sales - Expenses
In this case the sales figure is $750 and the expenses are $500.
By putting the values we have
Net Income = $750 - $500 = $250
Answer:
Gain recognized by Tom is $10000
So option (b) will be correct answer
Explanation :
We have given liability on bulding assumed by Paul Corp = $30,000
Tom's adjusted basis in the building = $20,000
Since the liability assumed by Paul Corp on the building is greater than Tom's adjusted basis, Tom must recognize gain equal to the difference between the liability on the building and his adjusted basis.
So gain recognized by Tom = $30,000 - $20,000 = $10,000
