An airplane traveling 245 m/s east experienced turbulence, so the pilot decided to slow down to 230 m/s. it took the pilot 7 seconds to get down to this speed. what is the acceleration of the plane? (round your answer to the nearest whole number.)

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
