Question

true or false? select all the statements that are true based on what was presented in the copper manufacturing video. glue is injected into copper powder. a printed copper part is not yet as strong as a machined copper part. tiny pockets of air in the copper part increase performance. williams says the product will be ready for widespread use within five years.

Explanation:

To determine the true statements, we analyze each option:

1. "Glue is injected into copper powder" – If the copper manufacturing video shows this step, it's true (checked, so assumed true from context).
2. "A printed copper part is not yet as strong as a machined copper part" – Typically, printed (additive manufacturing) parts may have lower strength initially than machined (subtractive) ones, so this is true (checked).
3. "Tiny pockets of air in the copper part increase performance" – Air pockets usually weaken materials and reduce performance, so this is false (uncheck).
4. "Williams says the product will be ready for widespread use within five years" – If the video doesn't state this (uncheck), so false.

Answer:

• Glue is injected into copper powder (True)
• A printed copper part is not yet as strong as a machined copper part (True)
• Tiny pockets of air in the copper part increase performance (False)
• Williams says the product will be ready for widespread use within five years (False)

(So the true statements are the first two checked ones.)
