Which increases along faults and leads to rock breaking? damage earthquake focus stress
A. damage
B. earthquake
C. focus
D. stress
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.

Compare the potential energy of two atoms chemically bonded to their potential energy when separated.
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 .

Answer:
Molecular formula = C₈H₁₆
Explanation:
Given data:
Percentage of hydrogen = 14.4%
Percentage of carbon = 85.6%
Molecular formula = ?
Molecular weight = 112 g/mol
Solution:
Number of gram atoms of H = 14.4/ 1.01 = 14.26
Number of gram atoms of C = 85.6/ 12 = 7.13
Atomic ratio:
C : H
7.13/7.13 : 14.26/7.13
1 : 2
C : H = 1 : 2
Empirical formula is CH₂
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
n = 112 / 14
n = 8
Molecular formula = n (empirical formula)
Molecular formula = 8 (CH₂)
Molecular formula = C₈H₁₆

Which statement best compares potential and kinetic energy?
Objects always have more potential energy than kinetic energy.
Kinetic energy increases and potential energy decreases when the velocity of an object increases.
Only potential energy decreases when an object’s height increases.
Objects always have more kinetic energy than potential energy.
Answer:
Its B) Kinetic energy increases and potential energy decreases when the velocity of an object increases.
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 energyKinetic 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:
Ec is the kinetic energy, which is measured in Joules (J).m is the mass measured in kilograms (kg). v is the speed measured in meters over seconds (m/s).Potential energyPotential 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:
Ep is the potential energy in joules (J).m is the mass in kilograms (kg).h is the height in meters (m).g is the acceleration of fall in m/s² (approximately 9.81 m/s²).Mechanical energyFinally, 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
Principle of conservation of mechanical energyThe 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.
Statement best compares potential and kinetic energyTaking 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.

Explain the electroplating process of an iron key with silver. the materials provided for electroplating is AgNO3 solution, silver rod and iron key.
Answer:
See explanation
Explanation:
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.
Which of the following best describes the velocity of an object?
A B0 m/s
B 30 m east
C 30 m/s east
D 30 m/s2
Answer:
[tex]\boxed {\boxed {\sf C. \ 30 \ m/s \ east}}[/tex]
Explanation:
Velocity is the vector measurement of the change in position over time. A vector measurement means the answer must include a magnitude (numerical value) and a direction.
Here are some units of velocity:
m/s (meters per second) kph (kilometers per hour) km/s (kilometers per second)There are many other units, but m/s is the most common.
We can eliminate choice B and D, because the units (meters-m and meters per second squared-m/s²) are not for velocity.
We are left with choice A (30 m/s) and C (30 m/s east). Remember, velocity needs a number and a direction. C contains the direction east, so it must be the correct answer.

During a chemical or physical change, energy may be...
a. created into another form
b. destroyed and reinvented into another form
c. converted into another form
d. disappeared
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.
What is law of conservation of energy ?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.
