The minimum radius of the curve to the vehicle to provide safe travel is 2339.2 ft
<u>Explanation:</u>
Given -
Speed allowed, v = 70mph
1 mph = 1.467 fps (feet per second)
Therefore, v = 70 X 1.467 fps
Superelevation, e = 0.05 inches/inch
Coefficient of side friction, fs = 0.09
Minimum radius of the curve, r = ?
We know,
r = v² / g ( fs + e/100 )
where,
g = acceleration due to gravity in feet
g = 32.2 lb.ft / lbf.s²
r = ( 70 X 1.467 )² / 32.2 ( 0.09 + 0.05 )
r = 2339.2 ft
Therefore, the minimum radius of the curve to the vehicle to provide safe travel is 2339.2 ft

Answer:
Specific gravity is 0.5 so option (a) is correct option
Explanation:
We have given mass of substance m =10 kg
Volume 
Density of substance is given by 
Specific gravity is given by 
So option (a) is correct option
Answer:
Option A
Explanation:
We know that ions are present in hydrogen-air flame and when the burning of an organic compound takes place in this flame more ions are produced in the flame.
Thus when we apply a voltage across this flame, the ion collector plate attracts the all the ions in the flame.
The presence of organic compounds increases the voltage across the hydrogen ion flame produced at the ion collector increases and as the voltage increases, the detection of the organic compound can be made in turn.
Thus flame ionization detector clearly responds to the variation in the collection of ions or electrons in a flame.
Hydraulic radius is caused by pressurized hydrogen air so that should mean the answer is hydraulic radius
