Nate wants to see if changing the voltage across a resistor changes the amount of current that flows through it. He plans to run five trials to test a series circuit with one resistor in it.

Which of the following should Nate keep constant in each trial?

A.

the number of trials he runs

B.

the current flowing through the resistor

C.

the voltage across the resistor

D.

the resistance of the resistor

Ascientific blank must be testable and capable of being proven false?

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
