Hello there!
The answer is the following:
Rapid energy transfer between Potential and Kinetic energy makes roller coasters thrilling.
Potential Energy is the energy related to the vertical position of the roller coaster cart. When it is at the highest point, the Potential Energy is at a maximum.
Kinetic Energy is the energy related to the speed of the roller coaster cart. When the cart is at the highest point, the kinetic energy is at a minimum, but as it begins to go down, the Potential Energy is transformed into Kinetic Energy, making the cart to increase its speed and making it a thrilling experience.
Answer:
R + 6 ohms
Explanation:
The current is the same in all three resistors
i = 2 amps
The problem is that the total voltage is unknown.
R = r
R1 =3 ohms
R2 = 3 ohms
The voltage drop is E = I*R
I = 2 amps
R1 = 3 ohms
R1 = 3 ohms
E = 3*2 = 6 volts
The second 3 ohm resistor also has 6 volts across it.
The total is 12 volts so far. But we know nothing more on how to solve for R.
All you can say is that the total resistance = R + 6 ohms
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
