Answer:
B) protons and neutrons
Explanation:
An atom has a nucleus made of protons and neutrons, and electrons surrounding the nucleus
Answer:
An energy source in which we use to power most powerplants and reactors.
Explanation:
Answer:
c. When they are traveling at low speeds, when they are almost stopped
Explanation:
The rate at which they ions loose energy depends upon its charge and mass and not on its speed. For example, We know that alpha particles have high mass and high charge so they loose more energy than gamma radiation which has no mass and no charge. The slower heavy particle which has high linear energy transfer.
Hence, when they travel at low speed they are almost stopped.
There the correct answer is option C
Answer: The correct answer is "The energy of the electrons emitted increases".
Explanation:
Photoelectric effect: It is the phenomenon in which the light of the particular frequency incidents on the surface of the metal then there is an emission of the electrons.
In this phenomenon, the saturation current increases with the increase in the intensity of the light.
The rate of flow of electrons constitutes the current. If the intensity of light increases then the rate of the electrons also increases.
In the given problem, When light is incident on a metal surface, it emits electrons. The rate of the electrons emitted increases.
Therefore, the correct option is (C).
