Molly and keitany ran the 7 mile (11.26 kilometers) falmouth road race. molly ran at a constant pace of 3: 05 per kilometer. keitany ran every one-kilometer interval in exactly three minutes and seven seconds. for example, keitany ran the one-kilometer distance from 4.57 kilometers to 5.57 kilometers in three minutes and seven seconds, and the one-kilometer distance from 10.1 kilometers to 11.1 kilometers in three minutes and seven seconds. at the end of the race, keitany finished ahead of molly. explain how. include a graph to support your reasoning.

Abox is pushed down at an angle of 32 degrees on a rough surface. the box moves to the right.what equation should be used to find the net force in the y-direction? answers: a. fnet,y = fn - fgb. fnet,y= fp - ffc. fnet,y = fn-fg- fpcos(32)d. fnet,y = fn-fg-fpsin(32)

What property of an object determines its inertia?

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
