In a geothermal power plant, the used geothermal water at 80°c enters a 15-cm-diameterhexagon and 400-m-long uninsulated pipe at a rate of 10 kg/s and leaves at 70°c beforebeing rejected back to the ground. windy air at 15°c flow over the pipe. disregardingradiation, determine the average wind speed that cools the water.

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.

total distance/total time

(85 + 82)/(5+3)

167/8

20 just over

i think its d if wrong im sorry
