Why is having a scientific model of the atom important? (2 points)

Models are used to prove which scientist is correct in a debate.

It is impossible to predict how atoms behave in nature.

The atom is the smallest known particle in the universe.

The model allows us to predict how atoms will behave in certain situations.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
