How long would it take for a penny to fall from the top of the empire state building? the building is 381 meters.

Without air resistance, the distance an object falls is

                     D  =  (1/2) (gravity) (time)²

                 381 m  =  (1/2) (9.8 m/s²) (time)²

                 (time)²  =  (381 m) (4.9 m/s²)

                             =  (381/4.9)  seconds²

                   Time  =  √(381/4.9 sec²)

                           =        8.8 seconds   (rounded)

Which principle states: "geologic processes taking place on earth today operated similarly in the past and can be used to explain past geologic events"? a. lateral continuity

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5
