The correct answer is
C. The battery
The battery is a device that provides a potential difference in the circuit, and so an electromotive force (e.m.f.) which pushes the electrons in the circuit from the negative pole towards the positive pole of the battery, so they move through the circuit. Therefore, it provides electrical energy.
Research has shown that the electrons orbit the nucleus in circular motions as shown on the classic Bohr model. FALSE
To solve this problem we will apply the concepts related to destructive interference from double-slit experiments. For this purpose we will define the path difference as,
Here,
= Wavelength
= Angle when occurs the interference point of destructive interference
Our values are given as,
Using the previous expression we have,
Therefore the distance between the two openings is 
Answer:
most light waves are scattered or are either reflected
Explanation:
the light waves bounce after hitting the mirror.
Answer:
The universe is the same in every location.
Explanation:
Astronomers are scientist that study the moons, galaxies, stars and planet. When the astronomers say that the universe is homogeneous, they mean that the universe appear the same in every location especially when it is viewed from a distance.
