Total resistance=R1+ R2= 6Ω
Voltage=12v
Current =
Current= 2A
In a series circuit, equal current passes through every resistance.
Answer is option A
Answer: Option (B) is the correct answer.
Explanation:
Convection is defined as a process in which a fluid (liquid or gas) is heated and the cooler liquid (more dense) settles or sinks at the bottom whereas a hotter material (less dense) will rises to the top.
For example, ice being less dense (cooler material) will float in a lake whereas liquid water being more dense will sink at the bottom.
Thus, we can conclude that situation in which convection currents most likely occur is within the water in a lake as ice forms on the top.
Examples of Newton's three law of motion.
First law of motion: A rocket being launched up in the atmosphere.
Second law of motion:while riding a bicycle, a bicycle acts as a mass and our legs pushing on the pedals of the bicycle is the force.
Third law of motion:when we jump off from the boat,the boat moves backward.

Velocity is displacement/time
(Displacement is the overall change in distance)
So you’ll want to divide 200 by 25, which should give you:
8 m/s
Answer:
A, 30V
Explanation:
First combine all resistors to an equivalent resistor. Since they are in series, the equivalent resistance is the sum of all resistor
Req = 20 + 40 + 60 = 120Ω
Using Ohm's law, find the current in the circuit
V = I * R
I = V / R
I = 60V / 120Ω
I = 0.5 A
Now the potential drop across the resistor R3 is the current times R3 resistance, therefore:
Vdrop = 0.5A * 60Ω = 30V
So the potential drop across resistor R3 is 30 V
