Answer:
The seed which is buried deep in the soil won't germinate
because
- it won't get sufficient oxygen / air
- it won't get sufficient sunlight
- and etc...
Chain reaction
Nuclear energy
Explanation:
Question 1:
Chain reaction:
A reaction in which when one occurs, it starts a series of other fission reaction is called a chain reaction.
Most nuclear reactions are chain reactions in which does not come to rest in one step like chemical reaction.
In nuclear reactions like which fusion and fission, one step leads to another until an atom attains stability or a stable product is formed.
The energy needed to sustain the chain process is produced in the previous reaction.
Nuclear energy:
The type of energy used in a nuclear power plant is called a nuclear energy. Nuclear energy is used to generate power in nuclear plant.
During a nuclear decay process, a huge amount of energy is released. This energy is channeled into electricity production and to do other useful works.
Nuclear energy is classified as a non-renewable source of energy.

Don’t mind me I just need to answer a question
Answer:
D
Explanation:
Methanogens are prokaryotes and therefore have prokaryotic cells. They are single-celled archaea. They are found in hypoxic conditions like the first stomach of ruminants where they digest molecules like cellulose and produce methane as a byproduct. The rest are composed of eukaryotic cells which are much larger than prokaryotic cells and their organelles are membrane-bound (unlike prokaryotes).
Answer:
9600 cm/min
Explanation:
Well, the circumference of the flywheel is 2π×the radius(16 cm). That's how far the spot moves in one revolution.
10 radians per second divided by 2π is the number of revolutions per second.
So multiply that times the circumference and that's the distance the point has traveled.
let the linear speed of the spot be v
therefore, v= 160×60= 9600 cm/min
