Metal bullets are considered mechanical vectors because they are inanimate objects that can physically transmit diseases or pathogens when they come in contact with a person's blood or tissues. Biological vectors, on the other hand, are living organisms like mosquitoes or ticks that can transmit diseases through bites.

What is the energy transformation in bending metal back and forth until it get hot?
When bending metal back and forth, mechanical energy is converted into thermal energy due to friction between the metal molecules. This friction generates heat, causing the metal to become hot.
Do pencil have metal?
Yes, pencils typically have a thin metal piece called a ferrule that holds the eraser in place. Additionally, some mechanical pencils have a metal tip that dispenses the lead as it is used.
How hard are bullets?
Bullets are typically made of metal, such as lead or copper, and they are designed to penetrate and injure targets upon impact. The hardness of a bullet can vary depending on its composition and purpose, but overall they are rigid and dense objects that can cause damage upon contact.
What is it called when a moving force wears down metal?
The wearing down of metal due to a moving force is called abrasion or mechanical wear. This can occur through processes such as friction, rubbing, or sliding between two surfaces.
What happens if you rapidly cool hot metal?
Rapidly cooling hot metal can cause it to become brittle and more prone to cracking or fracturing. This process, known as quenching, can introduce internal stresses in the metal due to the rapid temperature change. Additionally, the rapid cooling can also affect the metal's microstructure, altering its mechanical properties.
Are metal bullets mechanical or biological?
mechanicals
Was silver used in bullets?
Silver was used in bullets for quite a while. This metal proved to be very precious in making the bullets.
What is a very heavy metal used to make bullets. What metal has the chemical symbol Pb?

Are full metal jacket bullets illegal in Michigan?
Yes
What gun shoots most bullets in a second?

How do you make bullets in alchemy?

What does fmj stand for?
Full Metal Jacket.
What percentage of bullets have lead?
About 99%. Lead is an inexpensive metal that is soft and dense- 3 criteria for bullets. Most will be made of lead- if not entirely, they will have a lead core covered by another metal, such as copper.
What is a soft dense metal used in bullets and car batteries?
Lead
What machine guns use a metal strip to hold the bullets?
Japanese
Where are bullets made?
metal, powder and lots of violence. I like cheese
What is used to stop bullets in an indoor firing range?
The backstop. Usually a sheet of metal, set at an angle, bullets striking it are deflected down. Some strike a bed of sand, some water, some are deflected into a large round metal pipe, where the bullets spin until they stop.
