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.

Answer:
K and N
Explanation:
Ionic character depends on the electronegativity difference between the bonding elements. The greatest the elctronegativity diffference the greatest the ionic character. The electronegativity difference between K and N is the greatest among the four options as N is one of the most electronegative elements.
Answer:
the correct answer is torsional
Explanation:
For an adiabatic process Heat is not allowed to cross the boundary of the system.
So:
E.no heat flows into or out of the system
The correct answer is plasma.
When the temperature of a gas is very high, as it is, in extremely hot objects such as stars such as Sun,or incandescent or discharge lamps such as Neon lights, the gas exists in an ionized state.
At high temperatures, electrons gain enough energy to escape the attractive forces of the nucleus. When the electrons leave the atom, the atom becomes positively charged and these charged atoms are called ions.
At high temperatures, the matter can also contain neutrons which are neutral particles and are the constituents of the nucleus.
Thus the state at which matter can exist as ions, electrons, protons or neutrons is called plasma.
