physics
sorry. but i posted under the original question and got not response. but i tried this for part b and i got it wrong

physics
The pole vault landing pad at an Olympic competition contains what is essentially a bag of air that compresses from its "resting" height of 1.1 m down to 0.1 m as the vaulter is slowed to a stop. (a) What is the time interval during which a vaulter who has just clear...

A cylindrical air duct in an air conditioning system has a length of 3.5 m and a radius of 5.00 m. A fan forces air (ç = 1.8 Pa·s) through the duct, such that the air in a room (volume = 242 m3) is replenished every 12 minutes. Determine the difference in pressur...

A venturi meter is a device for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at a speed v2 through a horizontal section of pipe whose cross-sectional area A2 = 0.0600 m2. The gas has a density of ñ = 1.30 kg/m3. The Venturi meter has a ...
