Answer:
percentage change in volume = 0.00285 %
Explanation:
given data
bulk modulus = 3.5 × 
N/m²
bulk stress = 
N/m²
solution
we will apply here bulk modulus formula that is
bulk modulus = 
...............1
put here value and we get
3.5 × = 
solve it we get
bulk strain = 2.8571 × 
and
bulk strain = 
so that percentage change in volume is = 2.8571 × × 100
percentage change in volume = 0.00285 %
Answer:
Explanation:
Ohms Law I=E/R (resistive requires no power factor correction)
150/25= 6 amps
I think because if you’ve already turned it in they might as well grade asap instead of waiting
Answer:
(a) Flow rate of vehicles = No of vehicles per mile * Speed
=No of cars per mile * Speed +No of trucks per mile * Speed
= 0.75*50*60 + 0.25*50*40
=2750 vehicles / hour
(b) Let Density of vehicles on grade = x
Density on flat * Speed =Density on grade * Speed
So,( 0.75*50) * 60 + (0.25*50) * 40 = (0.75* x) * 55 + (0.25* x) * 25
So, x= 57.89
So, Density is around 58 Vehicles per Mile.
(c) Percentage of truck by aerial photo = 25%
(d)Percentage of truck bystationary observer on the grade= 25*30/60 * 25/55 =22.73 %
