Answer:

a) The values are: Fc = 4.15 N, Fi = 435.65 N, (F1)a = 640 N, and F2 = 239.6 N,b) Ha = 1863.75 N, nfs = 1, length = 11.8 mm

Explanation:

Given that:

γ= 9.5 kN/m³ = 9500N/m3 $T_1$

b = 6 inches = 0.1524 m

t = 0.0013 mm

d = 2 inches = 0.0508 m

n = 1750 rpm

$\frac{PV}{RT} = 1 + \frac{B}{V} + \frac{C}{V^2}$

$152.5 \ cm^3 /mol$ L = 9 ft = 2.7432 m $cm^6/mol^2$

Ks = 1.25

g = 9.81 m/s²

a)

$\frac{1800*V}{8.314*10^3*523.15} = 1+ \frac{-152.5}{V} + \frac{-5800}{V^2}$

$4.138*10^{-4} \ V= 1+ \frac{-152.5}{V} + \frac{-5800}{V^2}$

$4.138*10^4 \ V ^3 = V^2 - 152.5 V - 5800 = 0$

$4.138*10^4 \ V ^3 - V^2 + 152.5 V + 5800 = 0$

b) $\frac{PV}{RT}$

$\frac{1800*2250.06}{8.314*10^3*523.15}$

How does vegetation slow and prevent sediment loss?

Alekssandra [3086]

Vegetation cover serves as the most efficient and effective method to curb sediment loss. The roots of plants like grass interlink soil particles, aiding in erosion resistance, particularly against runoff water. Vegetation absorbs the force of raindrops, preventing soil particle detachment. Additionally, plants can lie flat resembling shingles on a roof, enabling runoff to travel over the soil rather than disturbing it. Tall, erect vegetation functions as a barrier against wind, diminishing its force so that it cannot dislodge soil particles from the ground surface.

1. If a car is traveling 90 mi/hr, how many feet will the car travel in 1 sec? In 5 sec?

alisha [2963]

Answer:

The vehicle travels 660 feet

Explanation:

Initially, convert the speed into Feet per second

The car's speed is 90 mi/hr

1 mi = 5280 ft

For 90 miles, we calculate 90 x 5280 = 475,200 feet

1 hour = 60 minutes

1 minute = 60 seconds

Therefore,

1 hour = 60 x 60 seconds = 3600 seconds

Speed is defined as the distance covered by an object over time. The speed formula is:

$Speed =\frac{distance}{time}$

$Speed =\frac{90mi}{1hr}$ ... given

$Speed =\frac{475200 ft}{3600sec}$

Speed = 132 ft/sec

Thus, time = 5 seconds

$Speed =\frac{distance}{time}$

$distance =speed\times time$

$distance = 132ft/sec\times 5sec$

Distance = 660 feet
