Hi! Your answer would be "node"
Explanation:
The Coulomb's law states that the magnitude of each of the electric forces between two point-at-rest charges is directly proportional to the product of the magnitude of both charges and inversely proportional to the square of the distance that separates them:
![F=\frac{kq_1q_2}{d^2}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7Bkq_1q_2%7D%7Bd%5E2%7D)
In this case we have an electron (-e) and a proton (e), so:
![F=-\frac{ke^2}{d^2}\\F=-\frac{8.99*10^9\frac{N\cdot m^2}{s^2}(1.6*10^{-19}C)^2}{(933*10^{-9}m)^2}\\F=-2.64*10^{-16}N](https://tex.z-dn.net/?f=F%3D-%5Cfrac%7Bke%5E2%7D%7Bd%5E2%7D%5C%5CF%3D-%5Cfrac%7B8.99%2A10%5E9%5Cfrac%7BN%5Ccdot%20m%5E2%7D%7Bs%5E2%7D%281.6%2A10%5E%7B-19%7DC%29%5E2%7D%7B%28933%2A10%5E%7B-9%7Dm%29%5E2%7D%5C%5CF%3D-2.64%2A10%5E%7B-16%7DN)
In this case, the electric force is negative, therefore, the force is repulsive and its magnitude is:
![F=2.64*10^{-16}N](https://tex.z-dn.net/?f=F%3D2.64%2A10%5E%7B-16%7DN)
To measure the strength of an earthquake, you can use either a Richter scale or Mercalli scale. Richter scale uses the amplitued of the wave and the distance from the source. Mercalli scale uses observations of people and is not considered to be scientific as Richter scale.
Answer:Whenever a moving object experiences friction, some of its kinetic energy is transformed into thermal energy. Mechanical energy is always transformed into thermal energy due to friction. Mechanical energy is always transformed into thermal energy due to friction.
