Pressure cookers have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). How much force (in N) must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 21.0 cm in diameter and the gauge pressure inside is 2.60 atm? Neglect the weight of the lid. N
A massless spring of constant 60N/m is attached vertically to a table. A 9-g balloon is filled with helium (density = 0.180 kg/m3 ) to a volume of 1.55m3 and is then connected to the spring, causing it to stretch to equilibrium distance d. Find d.

Q. 26. A cylindrical tank having radius R is half filled with water having density p. There is a hole at the top of the tank. The tank is moved horizontally, perpendicular to its length, with a constant acceleration equal to the acceleration due to gravity (g). Find the maximum pressure exerted by water at any point on the tank. Atmospheric pressure is Po. Assume that there is no spillage.
Ethanol is flowing in a pipe and at all points completely fills the pipe. At point A in the pipe the gauge pressure is p and the cross-sectional area of the pipe is 0.0500 m² . The other end of the pipe (point B) is open to the air, has cross-sectional area 0.0120 m2, and is at a vertical height of 9.00 m above point A. Part A What must the gauge pressure p be at A if the volume flow rate out of the pipe at point B is 0.0800 m /s? Express your answer with the appropriate units.
