B: how tall the plant is
Answer:
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
You didn't give us anything other than the question. No options are provided so I cannot answer. Nobody can.
Answer:
B. to the right
Explanation:
Given:
- distance of the test charge from +Q, r
- distance of test charge from +2Q, 2r
<u>Force on the test charge due to +Q:</u>

<u>Force on the test charge due to +Q:</u>

Since all the charges are positive here, so they will try to repel the test charge away. And the force due to charge +Q will be greater so initially the test charge will move rightwards away from the +Q charge.
C. Electrical current increases as resistance decreases
