Resistance is equal to relation between voltage and current.

$R = \frac{U}{I}$

If we express current:

$I = \frac{U}{R}$

If current is in fact 0 then one of the quantities either voltage or resistance must be equal to zero. Since resistance cannot be equal 0, because that would violate mathematical law that states that division by zero is undefined the only logical conclusion is voltage.

So the answer should be C voltage and B zero.

Hope this helps!

Answer:

1. Option C: Voltage

2. Option B: Zero

Explanation:

According to Ohm's law, the current in a circuit is directly proportional to the voltage. This means, when there is potential difference across the two ends of a circuit, then only current flows.

I ∝ V

$I = \frac{V}{R}$

If the given circuit has 0 A current, it means that either potential is zero or resistance is infinite. Practically, we cannot have infinite resistance. This means that the voltage must be zero.

While standing on the edge of the grand canyon, you see a rattlesnake and scream. You hear the echo of the scream off canyon flo

Answer:

1904 m

Explanation:

$\pink{\frak{Given}}\begin{cases} \textsf{ You scream after seeing a rattle snake .}\\\textsf{Scream is heard after 11.2 s .} \end{cases}$

Here we need to find out the depth of the canyon . When you will scream after seeing a snake , the sound produced will travel till the end of the canyon and after hitting the end , it will travel back to you .

So if the depth of the canyon is d (say) , then the total distance travelled by the sound wave will be d + d = 2d .

And we know that the speed of the sound is approximately 340m/s in air , so we can use the formula distance = speed * time to calculate the depth of the canyon . So ,

$\sf \longrightarrow Distance = (Speed)(Time) \\$
