Atypical cell phone consumes an average of about 1.00 w of electrical power and operates on 3.80 v. (a) what average current does the phone draw from its battery? (b) calculate the energy stored in a fully charged battery if the phone requires charging after 5.00 hours of use.

0.06925 A

18000 J

Explanation:

V = Voltage = 3.8 V

P = Power = 1 W

t = Time = 5 hours

Power is given by

The average current the phone draws from its battery is 0.06925 A

Energy is given

The energy stored in a fully charged battery is 18000 J

the one with the highest speed

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
