There are large numbers of charged particles in most objects. Why, then, don't most objects exhibit static electricity?
No charge is actually created or destroyed when charges are separated as we have been discussing. Rather, existing charges are moved about. In fact, in all situations the total amount of charge is always constant. This universally obeyed law of nature is called the law of conservation of charge
When enough energy is present, it can be converted into matter. Here the matter created is an electron–antielectron pair. (me is the electron’s mass.) The total charge before and after this event is zero
When matter and antimatter collide, they annihilate each other; the total charge is conserved at zero before and after the annihilation.

Why does the interaction of the sun's magnetic field and charged particles lead to a large decrease in the angular momentum of the sun?
Why are most organic compounds nonconducting and insoluble in water? Check all that apply. They don't conduct electricity because they are covalent, not ionic. Most organic compounds don't dissolve in water because they are polar. Most organic compounds don't dissolve in water because they are nonpolar. They don't conduct electricity because they are ionic, not covalent.
Object 1 is positively charged. Object 2 is neutral. Explain in detail WHY objects and 2 are attracted to each other by an electrostatic force. (I thought only oppositely charged objects are attracted to each other!) Use clear words and diagrams.
why do the leaves separate when charged? given that the electrical force is much stronger than the gravitational force why do you think the force between the leaves is small? what are some things you can do to avoid damaging static sensitive circuits with static electricity?
2. For "sufficiently large" objects moving "sufficiently fast" through a fluid (i.e. for large Reynolds numbers), the drag force on the object is proportional to the square of its ve- locity (quadratic drag). In this limit, we can ignore viscosity and argue this dependence from kinetic considerations. (a) (2 points) Suppose a sphere of radius R moves with speed v through a fluid with mass density ρ. In a small time interval dt, what is the mass m of fluid...
why does chimney swift immigrate in large numbers that individually?
Why do we need different tools for analyzing the financial statements? Don't the numbers in the financial statements speak for themselves?
The nominal interest rate is the 1)rate of interest charged to most large commercial borrowers. 2)the rate charged on loans for automobiles and other personal loans but not the rate charged on home loans. 3)equal to the real interest rate minus the inflation rate. 4)the interest rate that is corrected for inflation. 5)the interest rate that is not corrected for inflation.
Why do scientists need particle accelerators to discover new particles and to study the properties of known particles? charge greater than less Particle accelerators allow scientists to accelerate subatomic particles to very high speeds( the speed of light). At these speeds, collisions between the accelerated particles and particles in a stationary target have sufficient energy to produce new particles and/or known particles via energy conversion greater near For example, the mediators of the weak nuclear interaction have very large rest...
which two project management knowledge areas described in Exhibit 11.5 do you consider to be the most important? Why?
