Currently the Haber process uses up about 1% of the worlds energy supply and the energy used for this process is from natural gas. If we experience a shortage in natural gas, is it possible to efficiently do nitrogen fixation with electricity? I'm asking because I'm wondering if it would be viable to produce fertilizer using nuclear energy.

A projectile is shot from the edge of a cliff h = 245 m above ground level with an initial speed of v0 = 145 m/s at an angle of 37.0° with the horizontal, as shown in Fig. 3-39.
(a) Determine the time taken by the projectile to hit point P at ground level.
s
(b) Determine the range X of the projectile as measured from the base of the cliff.
km
(c) At the instant just before the projectile hits point P, find the horizontal and the vertical components of its velocity (take up and to the right as positive directions).
I got 115.8 m/s (horizontal component)
I got 87.26 m/s (vertical component)-is this right?
(d) What is the the magnitude of the velocity?
m/s
(e) What is the angle made by the velocity vector with the horizontal?
° (below the horizontal)


I don't get any of this. I don't know what they mean by range. Is magnitude the same as velosity?I don't understand what they are asking me to do.

If you calculate the resistance of a copper conductor using resistivity and the cross sectional area, you get a value that does not match the resistance given for the same conductor in the NEC. Does anyone know why?
ex. #2/0 in the NEC is .11 ohms/ 1000 ft.
if you take row *length/ area you get .0833 ohms/1000ft.
