That's the impression you get from the sound, that you call 'high' or 'low', determined by the FREQUENCY of the wave.

I hope this helps!
Explanation:
In contrast, dissolving a covalent compound like sugar does not result in a chemical reaction. When sugar is dissolved, the molecules disperse throughout the water, but they do not change their chemical identity.
I think it’s C but I’m not sure:/
Given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.
<h3>What is Current?</h3>
Current is simply the rate of flow of charged particles i.e electrons caused by EMF or voltage.
If a charge passes through the cross-section of a conductor in a given time, the current I is expressed as;
I = Q/t
Where Q is the charge and t is time elapsed.
Given the data in the question;
- Time elapsed t = 1hr = 3600s
- Current I = 350mA = 0.35A
We substitute our given values into the expression above to determine the charge.
I = Q/t
Q = I × t
Q = 0.35A × 3600s
Q = 1260C
Therefore, given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.
