What is the force of a spring called?
What is the force of a spring called? simple harmonic oscillations …the force is called the spring force. If x is positive (displacement to the right), the resulting force is negative (to the left), and vice versa. In other words, the spring force always acts so as to restore mass back toward its equilibrium position. […]
What is current a flow of?
What is current a flow of? Current was originally defined as the flow of charges from positive to negative. Scientists later discovered that current is actually the flow of negatively charged electrons, from negative to positive. What is the current in a wire? Electric current in a wire, where the charge carriers are electrons, is […]
What happens if the pinna is damaged?
What happens if the pinna is damaged? The outer part of your ear, known as the pinna, funnels sound into your ear canal, like a megaphone in reverse. If someone cut it off, everything would sound quieter. (A wound that scabbed over would make the sound suppression more severe.) Why does my Pinna hurt? Infection […]
What are the 4 basic forces?
What are the 4 basic forces? Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. What element is the most powerful? 1 Air/wind. Air control is the most strongest element there is. 2 Fire. Fire […]

Does sleep increase brain activity?
Does sleep increase brain activity? It is believed that dreaming occurs for at least 2 hours each night during REM sleep and that this activity plays an important role in the processing of information and the creation of memory. During this stage of sleep, heart rate and blood pressure increase and the activity of the […]
Can Potassium be radioactive?
Can Potassium be radioactive? Potassium (K) is a widely encountered element with a very small fraction of its atoms, about 0.012%, being radioactive. These K-40 atoms spontaneously decay, releasing electrons (beta radiation) as well as gamma rays. Both of these are capable of doing damage to tissues. How do you know if you are low […]
