As a hurricane passes through a region, there is an associated drop in atmospheric pressure. if the height of a mercury barometer drops by 21.4 mm from the normal height, what is the atmospheric pressure (in pa)? normal atmospheric pressure is 1.013 ✕ 105 pa and the density of mercury is 13.6 g/cm3 (note: this is g/cm^3, not si units of kg/m^3).

Identify the forces that contribute to the centripetal force on the object in each of the following examples: a. a bicyclist moving around a flat, circular track b. a bicycle moving around a flat, circular track c. a racecar turning a corner on a steeply banked curve
