Answer:
The atomic number 26(iron) is the threshold value below which the fusion might occur.
Explanation:
Nuclear fusion is a reaction in which two or more nuclei are combined to form one or more different atomic nuclei and subatomic particles.
Energy released in a fusion reaction is because of a key feature of nuclear matter called the binding energy which is a measure of the efficiency with which its constituent nucleons are bound together.
As we go up in atomic number, the energy released per nuclei goes down until it hits a minimum which is for atomic number 26 (iron) and fusion is not possible.
Answer:
Atomic no. 26 i.e. Iron
Explanation:
Nuclear Fusion is a process in which two or more nucleus are fused(combined) together to make heavier nucleus and release a lot of energy and other subatomic particles in the process. Considerable amount of energy is required to fuse the nucleus together but the output energy is much more than the input energy. It becomes an exothermic process.
In case of heavier nuclei, this doesn't hold true as the process becomes endothermic. That means the output energy will be way lesser than the input energy given to fuse the nucleus. This happens for elements of atomic no. 26 or above. Even in stars we can find element till atomic no. 26 as they can be formed by fusion. When a star reaches to iron fusion stage that is the end of it and it explodes into a supernova.
Self restraint
b.
Fairness
c.
Caution
d.
Honesty
By definition we have to:
It is the capacity that the human being has to think at the moment of acting before certain activities, about the possible risks that these can have, and modify their behavior so as not to receive or produce unnecessary damages.
In other words we can say that prudence means acting with caution in certain activities.
Answer:
Prudence means acting with caution.
c.Caution
The velocity a stroller is pushed from rest, accelerating at 500m/s is 7.5 m/s.
To find the final velocity of the stroller after it has traveled a certain distance while accelerating, one can calculate it using the third equation of motion:
v²-u² = 2as
The third equation of motion is one of the equations used in classical physics to describe the motion of an object with constant acceleration.
Given:
Acceleration, a = 500 m/s²
Distance, s = 6.32 m
The velocity is computed as:
v² - 0² = 2 × 500 × 6.32
v² = 6320
v = 79.5 m/s
Hence, the velocity a stroller is pushed from rest, accelerating at 500m/s is 7.5 m/s.

#SPJ1
Answer:
49 km/h
Explanation:
60 km/h acceleration for 0.75 hours.
60 × 3/4 = 45 km/h
Take the acceleration and add it to the speed the train was already moving at:
45 + 4 = 49km/h
Answer:
The correct answer is the Mesosphere. Mesosphere is the layer of the Earth's atmosphere that is directly above the stratopause and directly below the mesopause.
