Explanation:

because i took the test on edge 2020

Taking into account the definition of kinetic, potencial and mechanical energy, the tatement that best compares potential and kinetic energy is: Kinetic energy increases and potential energy decreases when the velocity of an object increases.

Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion.

Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.

The kinetic energy is represented by the following expression:

Ec= ½ mv²

Where:

Potential energy is the energy that measures the ability of a system to perform work based on its position.

Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity as follow:

Ep= m×g×h

Where:

Finally, mechanical energy is that which a body or a system obtains as a result of the speed of its movement or its specific position, and which is capable of producing mechanical work. Then:

Potential energy + kinetic energy = total mechanical energy

The principle of conservation of mechanical energy indicates that the mechanical energy of a body remains constant when all the forces acting on it are conservative (a force is conservative when the work it does on a body depends only on the initial and final points and not the path taken to get from one to the other.)

Therefore, if the potential energy decreases, the kinetic energy will increase. In the same way, if the kinetics decreases, the potential energy will increase.

Taking into account the definition of kinetic energy, when the velocity of an object increases the kinetic energy increases.

Therefore, considering the principle of conservation of mechanical energy, the potential energy decreases.

So, the correct answer is the second option:  Kinetic energy increases and potential energy decreases when the velocity of an object increases.

Explanation:

Answer:

See explanation

Explanation:

The essence of chemical bonding is in order to attain minimum energy. The minimum energy state is the most stable state of a chemical system.

As the distance of separation between atoms decreases, the potential energy of the system decreases accordingly.

An optimum distance is reached when the two atoms attain the lowest potential energy. This is designated as the bond distance of the two atoms.

Hence two atoms have lower potential energy when bonded than when separated at large distance.

When two atoms are chemically bonded they have Lower potential energies while when they are separated they have higher potential energies

The potential energies of atoms chemically bonded is directly proportional to the distance between the atoms ( i.e as the distance between atoms decrease the potential energies of the atoms decreases accordingly)  and this enables chemically bonded atoms to attain a more stable state.

The lower the potential energy of bonded atoms the more stable the element/compound  becomes therefore it is necessary that bonded atoms attain the least possible potential energy.

Hence we can conclude that When two atoms are chemically bonded they have Lower potential energies while when they are separated they have higher potential energies .

The process of electroplating an iron key with silver involves electrolysis.

The anode is a silver rod, the electrolyte is AgNO3 solution while the cathode is the iron key. A battery is connected to provide energy to drive the non-spontaneous electrochemical reaction.

Electrons flow from the anode to the cathode. Silver ions from the silver rod replenishes the silver that is deposited on the iron key in order to continue the electrolytic process.

The silver anode is therefore depleted in mass while the iron key increases in mass.

In the preparation of a microscopic slide, the items which are used are medicine dropper, scissors, and a slip cover. Thus, the correct option is D.

Microscope slides are made for the purpose of observations of different objects. After the observation, the slides are discarded. In most cases, the slides use a liquid mounting medium such as water or glycerin.

The procedure for the preparation of the slide is as follows:

1. Place a drop of liquid mounting medium in the center of the slide.

2. Position the sample on liquid with the use of tweezers.

3. At an angle, place one side of the cover slip against the microscopic slide making contact with outer edge of the liquid drop.

4. Lower the cover slip slowly, avoiding air bubbles.

5. Remove the excess water present in it with the help of paper towel.

Answer:

When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.

Explanation:

Answer:

The sun radiates energy in all directions. Most of it dissipates into space, but the tiny fraction of the sun's energy that reaches Earth is enough to heat the planet and drive the global weather system by warming the atmosphere and oceans. The delicate balance between the amount of heat Earth receives from the sun and the heat that Earth radiates back into space makes it possible for the planet to sustain life.

Answer: C: Converted into another form

Explanation: pues es esa calale y si va a hacer

During a chemical or physical change, energy is converted to another form. Energy cannot be created or destroyed. During a chemical reaction, physical change the energy and mass are conserved.

According to the law of conservation of energy energy can neither be crated nor be destroyed. Hence, the total energy of a system is always conserved.

However, energy can be transformed from one form to the other. Therefore, the energy lost in one form is gained in another form. For example, in all electrical devices, the electrical energy is converting to other forms of energy such as light, thermal , mechanical etc.

Similarly, during a chemical reaction, the energy released by a reaction system is equal to the energy absorbed by other reacting system. Similarly in electrochemical cells the chemical energy is converting to electrical energy.

Answer:

Stress

Explanation:

Stress increases along faults and leads to rock breaking. Therefore option D is correct.

Along faults, stress builds up in the rocks due to the movement and interaction of tectonic plates. Stress is the force applied to the rocks, and it can occur in various forms, such as compression, tension, or shear. As the stress increases, the rocks become more strained and are pushed to their breaking point.

When the stress exceeds the strength of the rocks, they can no longer withstand the applied forces and break, resulting in an earthquake. The release of accumulated stress along the fault causes the rocks to rupture and generate seismic waves, leading to ground shaking and the propagation of energy throughout the Earth's crust.

Therefore, stress is the primary factor that increases along faults and ultimately leads to rock breaking and the occurrence of earthquakes.

Answer: The main purpose of any warhead is to inflict damage on the target. The way the damage is caused may vary with different types of warheads, but in the most general sense, damage is caused by the transfer of energy from the warhead to the target. The energy is typically mechanical in nature and takes the form of a shock wave or the kinetic energy of fragments. In either case, a large amount of energy must be released. For many warheads that energy is stored in the form of chemical explosives.

Explosive Reactions

There are many chemical reactions that will release energy. These are known as exothermic reactions. If the reaction proceeds slowly, the released energy will be dissipated and there will be few noticeable effects other than an increase in temperature. On the other hand, if the reaction proceeds very rapidly, then the energy will not be dissipated. Thus, a great quantity of energy can be deposited into a relatively small volume, then manifest itself by a rapid expansion of hot gases, which in turn can create a shock wave or propel fragments outwards at high speed. Chemical explosions may be distinguished from other exothermic reactions by the extreme rapidity of their reactions. In addition to the violent release of energy, chemical explosions must provide a means to transfer the energy into mechanical work. This is accomplished by expanding product gases from the reaction. If no gases are produced, then the energy will remain in the products as heat.

Most chemical explosions involve a limited set of simple reactions, all of which involve oxidation (reaction with oxygen). A relatively easy way to balance chemical explosive equations is to assume that the following partial reactions take place to their maximum extent (meaning one of the reactants is totally consumed) and in order of precedence:
