Answer:
0.00899 N
Explanation:
The magnitude of the electrostatic force between two charges is given by the equation:
where:
is the Coulomb's constant
are the charges
r is the distance between the two charges
And the force is:
- Repulsive if the two charges have same sign
- Attractive if the two charges have opposite sign
In this problem we have:
(charge of object 1)
(charge of object 2)
r = 1 m (separation between the objects)
So, the electric force is
![F=(8.99\cdot 10^9)\frac{(1.0\cdot 10^{-6})^2}{1^2}=0.00899 N](https://tex.z-dn.net/?f=F%3D%288.99%5Ccdot%2010%5E9%29%5Cfrac%7B%281.0%5Ccdot%2010%5E%7B-6%7D%29%5E2%7D%7B1%5E2%7D%3D0.00899%20N)
Answer: 118 elements
Step-by-step explanation:
In the periodic table, the elements are sorted by atomic number. Therefore, as the list is sorted, there are 118 elements in total contained for the science periodic table.
Hope this helps!
Answer:A solenoid is a simple electromagnetic device consisting of a coiled electric wire, wrapped in a 3D circular pattern. When electric current is passed through the wire, the solenoid acts like a magnet with N and S poles at the ends of the coil.
When a ferromagnetic material rod is permanently placed inside the solenoid, the metal greatly increases the magnetic effect and becomes a permanent electromagnet. Moreover, it can also be used as an electrical switch by drawing in or pushing out a ferromagnetic material like an iron rod. Depending on the directions of the rod and the electrical current the switching action takes place.
Given figure represents the solenoid as electromagnet and the switching action.
