When you turn on a radio and hear music, at what approximate speed are the radio waves traveling? a. the speed of light b. 80% of the speed of light c. 50% of the speed of light d. less than half the speed of light

It really doesn't matter whether your radio is on or off, or what type of program content you prefer. As soon as the broadcast leaves the transmitting antenna, the radio waves travel at very close to 'c' ... the speed of light in vacuum ... even if there's nobody listening at all. (The slight, slight slow-down is due to traveling through air.)

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
