Gate-control theory
<h3>What is Gate-control theory?</h3>
According to the Gate Control Theory of Pain, the spinal cord has a system that allows pain signals to be amplified in the brain before being processed at the spinal cord itself, or attenuated there.
The mechanism that allows or prevents the passage of pain signals is known as the gate. The gate may be open or it may be closed, one of two possibilities:
- When the gate is open, pain signals can enter and are delivered to the brain, where they are perceived as pain.
- If the gate is closed, pain signals will be prevented from ascending to the brain and won't be felt.
The administration of a non-noxious (soothing or light rubbing) stimulus can help engage the gate control mechanism and alleviate pain in those who are exposed to painful (noxious) stimuli.

Answer:
its the sound that a heart produces when beating, this can help doctors detect abnormalities
Yes there is an elastic collision in physics its when a collision occurs but no kinetic energy is loss. We study them in order to understand how to conserve momentum.
I think it's something like electrons don't attract, cuz you know the saying "Opposites attract." Cause electrons are negative... Ahaha... sorry, I don't know the answer.
