Answer:
3.33 ohms
Explanation:
Parallel circuit :
1/Rtotal= 1/R1 + 1/R2 + 1/R3
1/Rtotal= 1/10 + 1/10 + 1/10
1/Rtotal=3/10
Therefore it Rtotal= 10/3=3.33 ohms
Two point charges, feel a force of 1. 0 n when they are 2. 0 cm apart. if they are moved further apart to 8. 0 cm. The electric force between them will be F2 = 1/16 J
A charged particle, also called an ion, is an atom with a positive or negative charge. This happens whenever something called an ionic bond forms. Two particles that have different numbers of electrons (the smallest particle in an atom which is negative) start reacting to each other.
According to Coulomb's law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges.
F1 = K q1*q2 / ![r1^{2}](https://tex.z-dn.net/?f=r1%5E%7B2%7D)
1 = K q1*q2 / ![2^{2}](https://tex.z-dn.net/?f=2%5E%7B2%7D)
F2 = K q1*q2 / ![r2^{2}](https://tex.z-dn.net/?f=r2%5E%7B2%7D)
F2 = K q1*q2 / ![8^{2}](https://tex.z-dn.net/?f=8%5E%7B2%7D)
F1 / F2 = 64 / 4
1 / F2 = 16 / 1
F2 = 1/16 J

Water displacement is the least difficult approach to decide the volume of an unpredictably formed or complex object. Rather than making various estimations and computations that might be inclined to error, it is just important to submerge the object in fluid and note the volume displaced. Ordinarily, this would be finished utilizing an aligned holder so the volume when inundation can be noted.
At the point when used to calculate the volume of a solid object, the drenching must be aggregate, and care taken to guarantee that no air is caught in any holes. Nonetheless, displacement can likewise be utilized to ascertain the heaviness of a vessel, in which instance obviously, the inundation isn't add up to; the vessel is permitted to drift and, as Archimedes broadly found, its weight will then be equivalent to that of the volume of water displacement.
