Answer:
D
Explanation:
calculate effective resistance of the resistors
= 80 + 120
= 200
overall resistance = 48 ohms
so overall current flowing through circuit
I = V / R
I = 12 / 200
I = 0.06 A
since circuit is in series, current is same at every point so...
potential difference across 80 = R x I
= 80 x 0.06
answer is potential difference = 4.8 V
hope this helps

I just learned this chapter recently
Answer:
The Fizeau–Foucault apparatus is either of two types of instrument historically used to measure the speed of light. The conflation of the two instrument types arises in part because Hippolyte Fizeau and Léon Foucault had originally been friends and collaborators.
Explanation:
<span>If your brakes go out, you will do the the following things:
1) Downshift to a lower gear.
2) If regular brakes are available, pump the brake pedal fast and hard to build up brake fluid pressure.
3) A</span><span>fter three or four pumps, i</span><span>f the brakes haven’t started working yet, do the third step: use the parking brake.
Slowly apply the parking brake and be prepared for the car to skid.</span>
Electrical Energy
A bolt of lightening is electrical energy. This is the same kind energy used by an electrical outlet. Electrical energy travels through power lines and then helps make lots of different machines work.
Motion Energy:
Moving things have energy. The faster something is moving, the more energy it has. Pose this question to your students: Which do you think has more motion energy, a book that is falling off a table or a truck driving down the road at 60 miles per hour? You can explain that the truck has more motion energy because it is traveling much faster than a book. Another reason why the truck has more motion energy is that the truck is much heavier than the book.
