Answer:
No. of transistors = 
transistors
Explanation:
Given that:
N = 
Y = 2025
N = 
N = transistors
Now at Y = 1980
Number of transistors N = 1920
Therefore,
18 ≅ 18.4 = Y - 1980
Y = 1980 + 18
= 1998
So, to increase multiples of 1000 transistors. it takes 18 years.

Answer:
0.07973 moles of O2 gas were produced
2.66 atm
Explanation:
Using the ideal gas equation
PV =nRT
P =pressure = 2.9 atm
V= volume = 720 mL = 720mL/1000= 0.72 L
n = number of moles = ?
R = the gas constant = 0.0821 atm L/(mol K)
T = temperature in Kelvin = 319 K
make n subject of the formula
n =PV/RT
n = 2.9 atm x 0.72 L / 0.0821 atm L/(mol K) x 319K = 0.07973 moles of O2 gas were produced
Pnew = atm?
P = nRT/V
= 0.07973 x 0.0821 atm L/(mol K) x 293K/0.72 L = 2.66 atm
Answer:
τ = 0.25 lbf/in²
Explanation:
given that the oil viscosity, μ = 2.415 lb/ft-s
gap between plates = 1/4 inches = 1/4*12 = 1/48 ft
recall from newtons law of viscosity;
shear stress τ = μ du/dy =
τ = (2.415 lb/ft-s) (10 ft/s)/(1/48) ft
τ = 1159.2 lb/ft-s²
we know that, 1 slug = 32.174 lb
lb = 1/32.174 slug
∴ τ = 1159.2/32.174 slug/ft-s² = 36 slug/ft-s²
τ = 36 slug/ft-s²
multiply both the numerator and denominator by ft, this gives
τ = 36 slug-ft/ft²-s²
τ = 36 lbf/ft² where 1 slug-ft/s² = 1lbf
since 1 ft = 12 inch = 1 ft² = 12² in² = 144 in²
∴ τ = 36/144 lbf /in² = 0.25 lbf/in²
τ = 0.25 lbf/in²
Answer:
Cost before adding taxes and incorporating variations
Explanation:
The sub-totals are basically sum of the cost from individual pages before including value added tax or any other tax depending with the state regulations. At this stage, contingencies and variation of prices are not considered. Therefore, the sub-total for building materials only include the materials on site or materials used as per the bill of quantities and certified by the engineer.
