Answer:
Bronze is made of the metals copper and tin.
Explanation:
Bronze is stronger than copper as an outcome of combining that metal with tin or different ores. Bronze is more quickly dissolved and is hence more comfortable to cast. It is also harder than pure metal and considerably extra immune to corrosion.
Pure copper is soft and can be formed into wire or pounded into wanted shapes. If the copper is consequently warmed (tempered), it can be performed soft again. Copper and zinc are blended to create brass, and mixed with tin to produce bronze.
This might be wrong,but im pretty sure its 0.10 m
(D)
Explanation:
Why (A), (B) and (C) don't make sense:
(A) you can't get high energies by breaking low-energy bonds. Simple law of energy conservation at work prevents it from happening.
(B) & (C) adding protons to the nucleus is not feasible due to the natural repulsion between protons. By the same token, protons cannot be removed from the nucleus by external means because of the incredibly powerful nuclear forces that bind the protons and neutrons together.
Why (D) is the correct answer:
It takes a lot of energy to hold the nucleus together. But by introducing neutrons into the nucleus, the nucleus can be rendered unstable and become radioactive. So when the nucleus breaks up, the energy that used to hold it together is now released and this energy can be harnessed to generate power.
