Answer:

C. nicotine

Explanation:

Nicotine is a derivative of tobacco, it can be found in smoke and stimulates the brain. It is produced by burning cigarettes and is the main cause of the dependence that the smoker presents. This is because, when you take a cigarette, nicotine reaches the brain in about 9 seconds and acts on the central nervous system, causing a pleasant feeling of well-being. However, this sensation is transient and the more one smokes the more the body adapts to the drug and the addiction increases, requiring more doses of nicotine in the body, ie increasing the amount of cigarettes consumed.

A doorknob makes it easier for you to open doors because it is what type of simple machine?
vagabundo [1.1K]

Answer: Wheel and Axle

Both of these work together to form a simple machine. You can't have one without the other.

If you try to turn just the axle itself, then you'll find it takes a lot of work. This is because the inertia of the axle wants to keep the object at rest. Also, you won't have a lot of torque due to the small radius compared to what a doorknob can offer.

Using a doorknob is like putting a (steering) wheel on an axle. This increases the radius and therefore increases the torque. You put in less work into the system and get more out of it.
