You've experienced convection cooling if you've ever extended your hand out the window of a moving vehicle or into a flowing water stream. with the surface of your hand at a temperature of 30°c, determine the convection heat flux for (a) a vehicle speed of 40 km/h in air at −8°c with a convection coefficient of 40 w/m2 · k and (b) a velocity of 0.2 m/s in a water stream at 10°c with a convection coefficient of 900 w/m2 · k. which condition would feel colder? contrast these results with a heat flux of approximately 30 w/m2 under normal room conditions

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.

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.
