Which type of engineer helps develop surgical instruments such as lasers and may develop artificial organs and limbs
Approximately how long ago is the big bang thought to have occurred
What is the primary focus of mechanical engineering
What are the biggest machines in the world used for
Learning more about subatomic particles

What type of combustion fuels produces the greenhouse gas carbon dioxide
All carbon based fuels produce carbon dioxide when burned. These include:
- fossil fuels (coal. oil, natural gas)
- alcohols
- bio-fuels (wood, charcoal, waste burning including cremation)
- specialty industrial fuels (acetylene etc.)
- carbon monoxide
Coal and petroleum are the two primary fossil fuels. Oxidizing methane also releases CO2, but that is 25 times better than releasing methane, itself an even more potent greenhouse gas.
As of 2006 what is a body in orbit around the sun that has a defined sufficient mass gravity and a clear orbit
In 2006, a planet became defined as a body orbiting the Sun that
has a mass of self gravity sufficient enough to make it nearly
round, and has a clear orbit.
