Calculating Current Density in Solar Wind: nLAe Method Explained

AI Thread Summary
To calculate current density in the solar wind using the nLAe method, it's crucial to maintain consistent units. The density of protons is given as 10.0 cm^-3, which can be converted to 10 million m^-3 for calculations. If using km/s for speed, density should be in km^-3 to yield results in Amps/(km)^2. Alternatively, keeping density in cm^-3 and converting speed to cm/s will result in units of Amps/(cm)^2. The user successfully resolved their calculation issue.

Near earth, the density of protons in the solar wind is 10.0cm^-3, and their speed is 691 km/s.
To find the current density I need to multiply (nLA)e

do i need to convert 10.0 protons cm^-3 to 10000000m^-3 because i tried that and it didnt work?
thanks.

This is a simple case that you need to use consistent units to get a sensible answer.

If you really want to use the units km/s for speed then you should use (km)^-3 for your density and expect an anwser in units Amps/(km)^2. Alternatively you could convert the speed to cm/s (leaving density in (cm)^-3) and that would get you an answer in units Amps/(cm)^2.
 
thanks,
i actually figured it out
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
