Q#1A pipe carries water horizontally at a pressure of 11.3 atm, with the water flowing at a speed of 2.0 m/s. The water is then to be diverted downwards and continue through a horizontal pipe located 2.3 m below the first segment of pipe (labelled as h in the diagram below). If the width of the pipe remains constant, what is the pressure of the water in the lower pipe in atmospheres? Use two digits of precision. Note that the density of water is 1000 kg/m3, and that 1 atm = 101.3 kPa.

Q#2)

Calculate the buoyant force on the spherical balloon to three significant figures, assuming a radius of (1.48x10^1) metres. The density of air is 1.29 kg/m^{3. please write the answer in this format. ex: (1.48x10^1)}

^Q#3)

You have (6.44x10^1) grams of a material with a density (1.0400x10^3) kg/m³. What is the volume in cubic metres? Give your answer with three significant figures.

Q#4) You mix 193 cm³of liquid 1, with a density of 0.35 g/cm^3, and 432 cm³of liquid 2, with a density of 0.71 g/cm³. Calculate the average density ing/cm³ with two digits of precision.

Q#5)

The pressure inside the International Space Station (ISS) is 101.3 kPa. Calculate the magnitude of the force in Newtons, on an exit door to the outside (where the pressure is zero). The rectangular door has a width of (6.22x10^1) cm and a height of (1.903x10^2) cm. Give your answer with three significant figures.
