Which statement best describes resistance? resistance is how well a current will flow in a material and is measured in volts. how well a material conducts an electrical charge and is measured in ohms. the ability of a material to attract a positive charge to create a current. the ability of a material to repel neutral charges and is measured in ohms. can any one ?

A resistor's unit is in Ohms so we can scratch the other units that says otherwise (volts). Peep the word "resist" as in, it resists the current flow and changes the electrical energy to thermal energy (produces heat). It shows how well something can conduct current with its value of resistance. So Resistance is how well a material conducts an electrical charge and is measured in ohms. 

Ithink the answer would be a

The anwser is: wave a has a greater pitch and frequency.
