When a jet plane is cruising at high altitude, the flight attendants have more of a "hill" to climb as they walk forward along t

he aisle than when the plane is cruising at a lower altitude. why does the pilot have to fly with a greater "angle of attack" at high altitude than at low?

Answer:

Probably because the Bernoulli effect (lift) is insufficient in thinner air to keep the plane aloft - increasing the angle of attack will increase the lift on the airplane

what is the resistance of a car light bulb that conducts 0.025A current when connected to a 12V car accumulator? is the current
Sophie [7]

One form of Ohm's Law says . . . . . Resistance = Voltage / Current .

R = V / I

R = (12 v) / (0.025 A)

R = (12 / 0.025) (V/I)

<em>R = 480 Ohms</em>

I don't know if the current in the bulb is steady, because I don't know what a car's "accumulator" is.  (Floogle isn't sure either.)

If you're referring to the car's battery, then the current is quite steady, because the battery is a purely DC storage container.

If you're referring to the car's "alternator" ... the thing that generates electrical energy in a car to keep the battery charged ... then the current is pulsating DC, because that's the form of the alternator's output.
