Two point sources of sound produce tones of 125 hz. the sources are generating sound in phase. in some coordinate system one source is at the origin and the other source is at latex: x₂ = 6.7 m. what is the absolute value of the phase difference (in radians) between the two waves at the point x=14.4 m? take the speed of sound to be 340 m/s.

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

It has more electrons than an neutral object
