electrostatics

Explanation:

The source of the earth's magnetic field is best explained by electrostatics, which is the area of physics that encompasses the study of electrical charges at rest. The electrostatic phenomena studied by this area of knowledge arise from the force of attraction and repulsion that electric charges exert on each other.

This knowledge allows the explanation of the earth's magnetic field, which is a gigantic magnetic distortion created by the earth's nucleus, which functions as a magnet, that is, it exerts forces of attraction and rupture. The core is divided into two parts, the inner part consisting of iron, nickel and other solid state metals, and the outer part, in which these elements are in liquid form.  The magnetic field protects the air layers by minimizing solar wind attacks. Without such a defense, the particles released by the sun would rip the atmosphere off the planet.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
