Your tiny cow has a mass of 1kg, and is standing in a field in Kansas, What force does Earth's gravity exert on the cow?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

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.

The strong nuclear force acts over a small distance than the electrostatic force. true or false
