Explanation:
Atoms don’t always fission the same way. You saw three different possible fission reactions for U-235
Answer: F
Explanation:
Weight = (mass) x (gravity)
Weight = (100kg) x (9.8 m/s^2)
Weight = 980 kg-m/s^2
Weight = 980 Newtons.
(about 220.5 pounds)
The weight of a 100 kg mass on Earth's surface is 980 Newtons(N). This is calculated using the formula 'w=mg', where 'w' is weight, 'm' is mass, and 'g' is the acceleration due to gravity on Earth (9.80 m/s²).
On earth, the weight of an object is determined by the gravitational force acting on it. This can be calculated using the formula w = mg, where 'w' is the weight of the object, 'm' is its mass, and 'g' is the acceleration due to gravity on Earth. Given that the mass 'm' is 100 kg and the acceleration due to gravity 'g' on Earth's surface is approximately 9.80 m/s², we can determine the weight of the object by substituting these values into the formula.
Applying these values into our equation, we get: w = (100 kg)(9.80 m/s²) = 980 N. Therefore, a 100 kg mass weighs 980 Newtons (N) on Earth's surface.
It is pertinent to note that an object's weight can vary based on its location as the value of 'g' changes with location. For instance, the value of 'g' on the moon is only about 1.67 m/s², which is far less compared to Earth, resulting in a lighter weight for the same mass.

Nuclear fusion and fission releases tremendous amount of energy using radioactive material as a fuel.
Fusion and fission are similar in that they both release large amounts of energy.
Nuclear fusion is a process in which two nuclei join to form a larger nucleus.
Nuclear fission is a process in which a nucleus splits into two smaller nuclei.
At first sight, it doesn’t make sense that both fission and fusion release energy.
The key is in how tightly the nucleons are held together in a nucleus. If a nuclear reaction produces nuclei that are more tightly bound than the originals, then the excess energy will be released.
It turns out that the most tightly bound atomic nuclei are around the size of iron-56.
Thus, if you split a nucleus that is much larger than iron into smaller fragments, you will release energy because the smaller fragments are at a lower energy than the original nucleus.
If instead you fuse very light nuclei to get bigger products, energy is again released because the nucleons in the products are more tightly bound than in the original nuclei.
