In this section of a circuit, a current of 5.0 A flows across R1. Find the potential difference between point a and point b. Let R1 = 3.0 ohm, R2 = 8.0 ohm, and R3 = 10.0 ohm.
Answers
B) 37 V
The potential difference between point a and point b is equal to 37 V
Explanation:
The potential difference across a and b can be calculated by finding the equivalent resistance of the resistors R1, R2 and R3 and then by applying Ohm's law.
Given:
R1 = 3.0 Ω
R2 = 8.0 Ω
R3 = 10.0
Current = I = 5 A
To calculate equivalent resistance of the circuit:
R2 and R3 are connected in parallel configuration. The equivalent resistance of R2 and R3 can be calculated as
Resistance R1 is in series with Rp. The equivalent series resistance is calculated as
Thus the given 3 resistor circuit can be written as an equivalent resistance Rs equal to 7.44 Ω through which current I passes.
By Ohm's law;
If V is the potential difference between a and b
Potential difference across points a and b = Current flowing through the circuit × Resistance between points a and b
37.2 V ≈ 37 V
Therefore, the potential difference between point a and point b is equal to 37 V
Answer:
Explanation:
37V

NaCl solutions are electrically conductive because they are a powerful electrolyte in which the constituent ions completely separate, resulting in free-moving ions in the solution.c Thus, option D is correct.
What best describes the properties of sodium chloride?
The ions (Na+& Cl) are free to move around and can thus function as charge carriers, since the motility of individual atoms or molecules in liquid state is significantly larger than that of solid state. Because of the free ions, molten sodium chloride is a good conductor of electricity.
The charged particles (ions) in solid “[NaCl]” cannot move because they are bound by powerful electrostatic forces, making it a poor conductor of electricity. They cannot conduct electricity as a result.
Therefore, NaCl solutions are electrically conductive because they are a powerful electrolyte in which the constituent ions completely separate, resulting in free-moving ions in the solution.

D. because sodium chloride is an ion
first of all , sodium chloride is salt and we all know that it is not malleable.
sodium chloride is an ion which do conduct electricity but not when they are solid.....they only do so when they are molten or aqueous ( dissolved in water )
sodium chloride is an ion. ions have high melting points.
D is true because as i have mentioned above , ions will conduct electricity when dissolved in water / aqueous or molten.......... HOPE IT HELPED !!!!!!

Formula: °F = (9/5) (°C) + 32 °C is given so I am solving for °F.
°F = (9/5) (25) + 32
=(1.8*25)+ 32
=45+32
=77
Answer= 77°F is equal to 25°C
A. Convert 35°C to °F
B. Convert 80°F to °C
C. Convert 15°C to °F
D. Convert 25°F to °C

completely worked out. The ONLY POSSIBLE reason that you
could still need help is that you're letting math scare you.
I'll do 'A' for you, 'B' most of the way, and get 'C' set up.
If THAT's not enough for you to run with and finish them all,
then you and I should both be embarrassed.
Write the formula on the wall:
°F = (9/5) °C + 32°
A). Convert 35° C °F = (9/5)(35°) + 32°
(9/5)(35) = 63 °F = 63° + 32°
°F = 95°
____________________________________
B). Convert 80°F to °C
The formula: °F = (9/5) °C + 32°
°F = 80 80 = (9/5)°C + 32
Subtract 32 from each side: 48 = (9/5)°C
Multiply each side by 5 : 240 = (9) C
Now you take over:
_________________________________________
C). Convert 15°C to °F.
The formula: °F = (9/5) °C + 32°
°C = 15 °F = (9/5) 15° + 32
(9/5) (15) = 27
Go ! °F =
