Answer:
the answer in this case would be single displacement reaction
Answer:
B: Electrical - Heat
C: Electrical - kinetic
Explanation:
When the hair dryer is plugged to electric supply, electrical energy is converted into heat. When this electricity is circulated through a resistor, heat is now created in the form of losses which make the air around the resistors to be heated.
After that process, this electricity turns into kinetic energy because it forms Electric energy which moves the fan in order to create a flow with the air that's heated.
Answer:
For it is a Globular Cluster
Explanation:
These Globular clusters are not considered to be a galaxies because they bond gravitationally to orbiting galaxies like the Milky Way and their masses are relatively small.
In globular clusters, the stars are closed together and they are like 70times closer to one another in their solar neighbourhood.
A globular cluster is a spherical collection of stars that orbits a galactic core. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes, and relatively high stellar densities toward their centers.
Yes this is true this causes day and night
Answer:
option A.
Explanation:
The correct answer is option A.
Nuclear power plant are used to generate electricity. In these power plant energy is produced by fission in the nuclear reactor.
The most common fuel used for the production of energy is U-235.
Control rods are inserted in the reactor if energy requirement is less and when energy requirement is large Control rods are remove. Hence, we can say that control rod can be used to regulate the reaction in the nuclear power plant.
