The correct answer to the question is- C).Electrons are ripped off one material and held tightly by the other material.
EXPLANATION:
Before going to answer this question, first we have to understand the charging by friction.
There are three modes of charging a body, which are known as friction,conduction, and induction.
Friction: Friction is the type of charging a body due to the actual transfer of electrons when two substances of different electron affinities are rubbed with each other. During rubbing, the electrons from less electron affinity substance will be transferred to high affinity substance.
The substance which will accept electrons gets negatively charged, and the other substance will be positively charged.
There will be no transfer of protons from one substance to another as protons are bound inside the nuclei of atoms.
Hence, the correct answer to the question is that electrons are ripped off one material and held tightly by the other material.
(C)

The answer is a path of destruction up to 50 miles long with destroyed trees and homes.
Tornadoes form from severe thunderstorms. Wind in the higher altitude of the storm moving at a greater velocity than wind at a lower altitude creates a vertical wind shear. The faster-moving winds aloft come from the west and create an updraft when they meet slower-moving wind close to the ground that is moving in the opposite direction. As warm surface air moves upward into the thundercloud, the rotating air creates a vortex.

Conveniently, some scientists have already figured out how much heat energy it takes to increase the temperature of one gram of water by exactly 1 degree Celsius. That is called the specific heat of water and it's value is 4.184J/g.
So simply multiply the specific heat with the number of grams and the number of degrees C like this:
Particles stay the same unless there is a chemical change whether the matter is solid, liquid or gas. ... When substances change state there is no change in mass so if 100 g of ice is melted 100g of water are formed this will boil to form 100g of steam (this is called "conservation of mass").
