Answer: 219 Ohms, C

Explanation:

To find the resistance, you can use Ohm's Law:

V = IR

Where V is the voltage, I is the current, and R is the resistance.

9.2 = 0.042R\\\\\frac{9.2}{0.042} = R

Solving for R gives us around 219 Ω.

A point charge is released from rest in a region containing an electric field. The charge will start to move
kotykmax [81]

Answer:

b) in a direction that makes its potential energy decrease.

Explanation:

  • As the electric field has the direction that would take a positive test charge under its sole influence, the positive test charge, will have an increase in its kinetic energy.
  • Due to the conservation of energy, in absence of non-conservative forces, this increment must be equal and opposite  to the  change in electric potential energy, which will be always negative, independent of the sign of the charge.
