In a direct current the electric charge flows in one direction.
in an alternating the electric charge changes in its direction periodically.
Answer:
The answer is b the radiation of the suns electromagnetic waves
Explanation:
I took the Quiz to.
<em>mass (m)= 5 kg</em>
<em>height (h)= 9m </em>
<em>gravity (g)= 9.8 m/s^2</em>
It has Potential energy. (PE)
• PE = mgh
Replacing:
PE = 5 * 9.8 * 9 = 441 Joules
Because they eventually erode and then break and end up forming underwater.
