Ohm’s law is represented by the equation i=v/r. explain how the current would change if the amount of resistance decreased and the voltage stayed the same. (hint: try plugging numbers into the equation for r, but make sure v stays the same. then describe what happens to i(current)

Trumpeter a holds a b-flat note on the trumpet for a long time. person c is running towards the trumpeter at a constant velocity. person b is running away from the trumpeter at the same rate. person d is standing still the whole time. which person hears a frequency that is lower than the b-flat?

Apackage of supplies is dropped from a plane, and one second later a second package is dropped. neglecting air resistance, the relative velocity of the 1st package viewed from the second will 56) a) increase. b) be constant. c) be zero. d) depend upon their weight. e) decrease

What is the difference between mass density and weight density?
