Answer:
The energy yield for one gallon of ethanol is 2.473 %.
Explanation:
The net energy yield (
), expressed in percentage for one gallon of ethanol is the percentage of the ratio of the difference of the provided energy (
), measured in Btu, and the energy needed to produce the ethanol (
), measured in Btu, divided by the energy needed to produce the ethanol. That is:
(1)
If we know that 
and 
, then the net energy yield of 1 gallon of ethanol:
The energy yield for one gallon of ethanol is 2.473 %.
Maybe because of shipping costs and if you need to buy materials from a far place such as different international travels?
Answer:
The truck will not stop in time. The truck passes the stop sign by about 63.41 ft before it stops.
Explanation:
The distance that the truck starts slowing down = 80 ft from the stop sign
Using equations of motion, we can calculate the distance it will take the truck to stop, then check of it is less than or more than 80 ft.
u = initial velocity of the truck = 40 mph = 58.667 ft/s
v = final velocity of the truck = 0 ft/s (since it comes to a stop eventually)
x = horizontal distance covered during the deceleration
a = Deceleration = -12 ft/s² (it'll have a negative sign, since it is negative acceleration
v² = u² + 2ax
0² = 58.667² + 2(-12)(x)
24x = 3441.816889
x = 143.41 ft
143.41 ft > 80 ft; hence, the truck will not stop in time. The truck passes the stop sign by about 63.41 ft before it stops.
Umm... Heck no, that is very dangerous and could cause you to loose a finger... OR A HAND. To be safe I would always turn it off but if the saw has an on and off switch and a rev switch I think it would be ok.
