Question 1 Suppose you have a horizontal section of a pipe as shown below, where water is entering on side that
has a diameter of 0.5 m with a speed v = 6 m/s. The water leaves the pipe at the narrower section,
which has a diameter of 0.25 m. At what speed does water leave? (2 marks)​

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

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.
