List three cases in which potential energy becomes kinetic energy and three cases in which kinetic
energy becomes potential energy

Answers

Answer 1
Answer: 1 Electrical Potential Energy, separating two charged plates will store energy as the plates want to return to their original position. 

2 Spring or Elastic can be stretched to store energy as it wants to return to rest 

3 Gravitational energy is stored by moving something (ball or pendulum are both examples of this) against a gravity gradient (lifting an object) that wants to fall back down.

Where are most faults located? And what is a fault in science terms?

Answers

You can almost ALWAYS find a fault at the edge of a boundary or between the earths' surface and the fault plane. A fault in scientific terms is basically just a crack in the earth's surface that has movement among the fault.

Which two particles in an atom are equal in number

Answers

If you mean in mass, then the mass of one proton is approximately equal to the mass on one neutron. If you mean how many of each, then the number of protons is equal to the number of electrons. If the number of electrons was different from the number of protons, then you'd have an ion. An ion with a positive charge is a cation, and an ion with a negative charge is an anion.

Protons and electrons are the two equally abundant particles in an atom.

The atom's nucleus contains protons, which are subatomic particles with a positive charge. A +1 positive electric charge permeates each proton.

An atom's nucleus is surrounded by electrons, which are subatomic particles with a negative charge. An electric charge of -1 is carried by each electron.

The number of protons in the nucleus of a neutral atom is equal to the number of electrons encircling the nucleus. The atom becomes electrically neutral when the balance of positive and negative charges results in a net electric charge of zero.

An atom with the atomic number 6 for carbon, for instance, contains six protons and six electrons. Similar to this, an atom of sodium, which has an atomic number of 11, contains 11 protons and 11 electrons.

An atom is stable and maintains its distinctive chemical properties because it has an equal number of protons and electrons.

Why is a car rounding a curve accelerating, even if it is moving at a constant speed?

Answers

Because "acceleration" does NOT mean "speeding up". It means ANY change in the speed OR direction of motion. Speeding up, slowing down, and changing direction are all 'accelerations'. If a car is not moving in a straight line, then its direction is changing and it is accelerating, even if its speed is constant.
Automobile speedometers give an instantaneous velocity. It is important to remember that because the velocity has a direction, a change in either the speed or the direction results in a change in velocity. This leads to an interesting fact, a car going around a curve can have a constant speed and yet still have a changing velocity. The car in the following diagram is traveling around a curve. Suppose the driver looks at his speedometer when the car is at points "A", "B", and "C". At each of these points he notices that the speedometer reads 30km/h. His speed is a constant 30km/h as he rounds the curve. Now look at what is happening to his direction of motion. As he goes around the curve, his direction changes from East to South. Because of this change in direction, we have to conclude that his velocity is changing even though his speed is constant.

Fill in the blank. The gravitational attraction between two objects will ----------- if one object acquires more mass.

Answers

Well,

The Second Universal Law of Gravitation states that "The gravitational attraction between two masses is directly proportional to the mass of each individual object."  That means that if one object gains mass and the other object retains its mass, then gravitational attraction between them will increase.

So, the missing word is "increase."

That's easy.  Once we cut through all the scientific jargon,
we realize it's as simple as:
