Answer:
Explanation:
Total Stopping distance is the sum of the reaction distance and the braking distance, such that ;
d=dr + db =1.47St +[ ( Si 2- Sf2 ) / 30(F/0.01G) ]
In this case, the reaction time, t, is the AASHTO standard, or 2. 5 s. The friction factor, F, is based upon the standard AASHTO deceleration rate of 11.2 ft/s2 (F = 11.2/32.2 = 0.348) and the speed is given as 40 mph.
d = 1.47x60x2.5+ [ (60^2-40^2) / 30x 0.348 ]
d = 220.5 + ( (3600-1600) / 10.44 )
d = 220.5 + 191.57
d = 412.07ft.
Since the sign can be seen clearly at 120 ft.
Then the position of the sign should be,
= 412.07 - 120
= 292.07 ft
Answer: Your question has some missing figures so kindly plug in the values into the solution provided to get the exact amount of money saved
answer : Electric power generated = 216 * 10^6 kJ
money saved = $0.XY * 60000 kwh
Explanation:
<u>Calculating the amount of electric power generated by wind turbine</u>
power generated = ( 30 * 2000 ) kWh = 60000 kWh
Electric energy generated = 60000 kWh * 3600 kJ = 216 * 10^6 kJ
<u>Calculate money saved by school per year </u>
$0.XY * 60000 kwh

4. Engine
5.Air tank
6.Pressure gauge
7.Stand
8. Gate valve
b)
The efficiency of air engine is less as compare to efficiency of electric engine and this is not ecofriendly because it produce green house gases.These gases affect the environment.
c)
it can run around 722 km when it is full charge.
