Answer:
Explanation:
Given that
Superelation= 0.08ft/ft
Given curve= u•
Curve junction factor= 0.13
DR= 5729.57795
R = 5729.57795/D
R = 5729.57795/4
R = 1432.4ft
c + f = V^2/gG
0.08 + 0.13 = V^2 / (32*1432.4)
V^2 = 9625.728 or V = 98 ft/sec
The designed speed for a project considered is a minimum value which means the highway design elements will meet or exceed the standards for the design speed. The maximum safe speed under normal condition is significantly greater than design speed
Answer:
Explanation:
Given that,
Charge through a wire is
Q = 4000C
Time for charge to pass through the wire is
t = 50seconds
Then,
Current through the wire is the rate of charge passing through the wire
Q = it
Where
Q is charge.
I is current
t is time taken
Therefore,
I = Q / t
I = 4000 / 50
I = 80 Amps
Explanation:
proton number + neutron number = atomic mass
30 + 35 = 65
Liquids<span> are not </span>packed<span> as tightly as </span>solids<span>. And gases are very loosely </span>packed<span>. The spacing of the molecules enables </span>sound<span> to travel much faster through a </span>solid<span> than a gas. </span>Sound<span> travels about four times faster and farther in water than it does in air.</span>
A) TOTAL Resistance = 41+18+120 = 179 ohms
<span>Current = V/R = 9 / 179 = 0.0503 A = 50.3 mA </span>
<span>B) V = I*R = .0503 * 41 = 2.06 V </span>
<span>C) V = I*R = .0503 * 18 = 0.91 V </span>
<span>D) V = I*R = .0503 * 120 = 6.03 V</span>
