Answer:
Explanation:
According to Gauss's Law, the electric flux of a charged sphere is the electric field multiplied by the area of the spherical surface:
This is identical to the electric flux of a point charge located in the center of the sphere.
Answer:
hi there!!
Explanation:
Nickel 149 pm
Cobalt 152 pm
Calcium 194 pm
Potassium 243 pm
So Potassium is the correct answer
Answer:
The particles have just enough energy to move past each other.
A, B, and C are all incorrect because they are talking about springs. I'm assuming you're talking about a 2 dimensional, side to side pendulum. In that case, the answer is D because as the pendulum goes up from one side, gravity accelerates it downward until it swings to the other side. If you're not talking about this type of pendulum, leave a comment and ill come back.
Light can be seen as an electromagnetic wave.
What happens when two waves, with the same frequency, superpose is called interference.
If at a certain point two waves arrive both with a crest, we have constructive interference and the amplitudes sum up, reaching the maximum value, resulting in bright spots.
If at a certain point one of the waves arrives with a crest and the other wave arrives with a trough, we have destructive interference, and the two amplitudes cancel out, resulting in dark spots.
Therefore, t<span>he dark bands on the wall are from destructive interference.</span>
