Answer:
a) C. 7.5 V
b) A. 2.5 V
Explanation:
First, we find the total resistance of the circuit. A voltage divider circuit is a series circuit. Therefore, its total resistance will be the sum of individual resistances:
a)
Now, we will apply the voltage divider rule on this circuit to find the voltage across the 300 Ω Resistor (R₂):
V₂ = 7.5 V
Therefore, the correct option is:
<u>C. 7.5 V</u>
<u></u>
b)
Now, the voltage across the 100 Ω Resistor (R₁) will be:
Therefore,the correct option is:
<u>A. 2.5 V</u>

Answer:
R = 620.0 Ω +/- 5%
Explanation:
According to the standard color coding for carbon resistors, the first color represents the first digit, the second the second digit, the third is the multiplier factor (10*x), and the fourth (if existing) defines the tolerance.
In our case, we have:
Blue = 1st digit = 6
Red = 2nd digit = 2
Brown = Multiplier = 10*1 = 10
Gold = Tolerance = +/- 5%
⇒ R = 62*10 = 620.0 Ω
Tolerance = +/- 5%
Answer:
0.71 m
Explanation:
Let the 5 kg is hang at a distance d from the midpoint.
use the concept of moments.
take moments about the mid point.
Anticlockwise moments = clockwise moments
3 x (0.5 - 0.15) = 5 x d
1.05 = 5 d
d = 0.21 m
So, the distance of 5 kg from 0 mark on the stick is 0.5 + 0.21 = 0.71 m
There are 1000 milliliters (mL) in a liter (L). Remember that the prefix milli- means one thousandth.
Since Tony made 14 liters, that means he made:
His guests drank 9500 mL, so subtract from the total amount of lemonade made to get the amount left over:
------
Answer: 4500 mL
