A bullet is made up of what substance?

To find out what substance a bullet is made up of, we can refer to the field of materials science and manufacturing processes used in bullet production. Generally, bullets are made up of a combination of different materials. The most common types of bullets are made up of a lead core that is enclosed within a jacket made of copper or a copper alloy.

Here's how to find the answer:

1. Start by understanding basic knowledge about bullets, including their composition and manufacturing process.
2. Research bullet manufacturing processes and materials used in bullet production. This can be done by referring to authoritative sources such as textbooks, scientific journals, or reputable websites focused on metallurgy, firearm technology, or ammunition manufacturing.
3. Look for information regarding the composition of bullets, paying attention to the materials used in the core and jacket.
4. Analyze the gathered information to identify the consensus view among experts in the field. Cross-referencing multiple sources can help establish a reliable answer.

In summary, by researching bullet manufacturing processes and materials used in bullet production, we can determine that a bullet is typically made up of a lead core enclosed within a copper or copper alloy jacket.
