Direct current (DC) is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that periodically reverses direction.

When somebody hands you a Celsius°, it's easy to find the equivalent Fahrenheit°.
Fahrenheit° = (1.8 · Celsius°) + 32° .
So 100°C works out to 212°F.
It's also easy to find the equivalent Kelvin. Just add 273.15 to the Celsius.
So now you can see that 100°C is equal to A and D,
and it's less than B .
The only one it's greater than is C .

An electrically charged element is called an "ion". A neutral element is an atom.
Answer:
0.78333 m/s in the opposite direction
1.566 m/s in the same direction
Explanation:
= Mass of penny = 0.0025 kg
= Mass of nickel = 0.005 kg
= Initial Velocity of penny = 2.35 m/s
= Initial Velocity of nickel = 0 m/s
= Final Velocity of penny
= Final Velocity of nickel
As momentum and Energy is conserved
From the two equations we get
The final velocity of the penny is 0.78333 m/s in the opposite direction
The final velocity of the nickel is 1.566 m/s in the same direction
