Technician b says that hydrogen has better specific energy than fossil fuels. so technician b is correct.
<h3>
Does hydrogen have the highest specific energy?</h3>
- Although hydrogen has the highest energy density per mass of any fuel, it has the lowest energy density per unit volume due to its low ambient temperature density, necessitating the development of new storage technologies with the potential for higher energy density.
- Hydrogen is utilized as a rocket fuel and in fuel cells to generate power on some spacecraft because it is beneficial as an energy source or fuel due to its high energy content per unit of weight.
- Since hydrogen has a significantly higher energy content than fossil fuels, less of it is required to carry out any given task.

Answer:
0.867
Explanation:
The driver population factor (
)can be estimated using the equation below:
![f_{p} = \frac{V}{PHF*N*f_{HV}*v_{p}}](https://tex.z-dn.net/?f=f_%7Bp%7D%20%3D%20%5Cfrac%7BV%7D%7BPHF%2AN%2Af_%7BHV%7D%2Av_%7Bp%7D%7D)
The value of the heavy vehicle factor (
) is determined below:
The values of the
= 2 and
= 3 are gotten from the tables for the RVs, trucks and buses upgrades for passenger-car equivalents. Therefore:
= 1/[1+0.08(2-1)+0.06(3-1)] = 1/[1+0.08+0.12] = 1/1.2 = 0.833
Furthermore, the vp is taken as 2250 pc/(h*In) from the table of LOS criteria for lane freeway using the 15 minutes flow rate. Therefore:
= 3900/[0.8*3*0.833*2250] = 3900/4498.2 = 0.867

The switch has been in position a for a long time. At t = 0, the switch moves from position a to position b. The switch is a make-before-break type so there is no interruption of the inductor current. a. Find the expression for i(t) for t ≥ 0. b. What is the initial voltage across the inductor after the switch has been moved to position b? c. Does this initial voltage make sense in terms of circuit behavior? d. How many milliseconds after the switch has been put in position b does the inductor voltage equal 24V? e. Plot both i(t) and v(t) versus t
