1–16 the pascal (pa) is actually a very small unit of pressure. to show this, convert 1 pa=1 n/m21 pa=1 n/m2 to lb/ft2lb/ft2. atmosphere pressure at sea level is 14.7 lb/in214.7 lb/in2. how many pascals is this?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
