Answer:
B. Electrons are transferred from the fur to the plastic rod.
Explanation:
Triboelectricity or friction charging refers to the ability of materials to gain or lose electrons as a result of rubbing them against something. This phenomenon has been observed in the case of rubbing plastic rod against fur, or glass rod against silk.
In the context of rubbing plastic rod against fur, what happens is that the fur which has an excess of charges loses electrons to the plastic rod. This makes the plastic rod to become positively charged, and the fur, negatively charged.
The First Quarter Moon is a primary Moon phase when we can see exactly half of the Moon's visible surface illuminated. If it is the left or right half, depends on where you are on Earth.
The best thermal conductor is b. metal
It will have the strongest attraction for a conductor.
Answer:
Fusion
Fission
Explanation:
The first problem describes a nuclear fusion process. In this process;
- small atomic nuclei combines to form a larger one.
- it is accompanied by a large release of energy
- this energy provides the needed temperature to set up another light nuclei to fuse.
The second problem describes nuclear fission,
- a heavy nuclide is bombarded with a neutron.
- the product formed becomes unstable and subsequently breaks down.
- This leads to a series of chain reactions until stability is attained.
