Una corriente I fluye por un cable de radio R. Si se distribuye de tal manera que la densidad de corriente volumétrica sea proporcional a 1(ρ+R)2, es decir J⃗ alfa 1(ρ+R)2z^
La constante de proporcionalidad correcta β que vuelve dimensionalmente consistente la ecuación es:

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
