Answer:
[tex]\boxed {\boxed {\sf 1, 242 \ N}}[/tex]
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F=ma[/tex]
In this formula, F is the force, m is the mass, and a is the acceleration.
The mass of the object is 540 kilograms and the acceleration is 2.3 meters per second squared.
m= 540 kg a= 2.3 m/s²Substitute the values into the formula.
[tex]F=(540 \ kg)(2.3 \ m/s^2)[/tex]
Multiply.
[tex]F=1242 \ kg*m/s^2[/tex]
Conver the units. 1 kilogram meter per second squared is equal to 1 Newton. Therefore, our answer of 1242 kilogram meters per second square is equal to 1242 Newtons.
[tex]F= 1242 \ N[/tex]
The force of the object is 1242 Newtons.

11) When sodium metal is subjected to violet light, it causes the photoelectric effect. However, red light does not affect
the sodium. Explain this phenomena.
The phenomena in which violet light causes photoelectric effect and red light does not is because red light does not achieve the minimum frequency for the phenomenon to occur but violet light does.
The phenomenon in which a substance emits electrons when light is incident upon it is called the photoelectric effect.
This electron would not be emitted if the frequency of the light does not exceed a minimum frequency called the threshold frequency.
Since in the case of the sodium metal, violet light causes the photoelectric effect while red light does not.
This implies that red light does not exceed the minimum frequency for the photoelectric effect to occur, but violet light does thereby causing the photoelectric effect to occur.
So, the phenomena in which violet light causes photoelectric effect and red light does not is because red light does not achieve the minimum frequency for the phenomenon to occur but violet light does.

Graphite conducts heat in a similar way to metals because it contains __________ __________. What two words complete the sentence?
Answer:
Free electrons
Explanation:
Graphite conducts heat in a similar way to metals because it contains free electrons.
Conductivity is arised from the delocalization of free electrons. Metals are electron rich and conduct thermally and electrically. Graphite conducts heat in a similar way because it contain delocalized electrons.
What is graphite?Graphite is an allotrope of carbon as diamond and fullerenes. Graphite exhibits a layered helical structures in which the carbon atoms are arranged in a hexagonal fashion.
Substances conduct electricity and heat when they are rich in electrons and are mobile to pass through it. Metals are electropositive and they contains extra electrons which can be delocalized between orbitals or energy levels.
This delocalization of electrons results in an a thermal or electrical current in the substance. Carbon is in sp2 hybridisation in graphite. Where, the electrons can transit from one layer to the other in the layered structure.
Therefore, the presence of delocalized electrons make graphite conducting.

5 example of similarities between compression and tension stress?
Answer:
Mark me as Brainliest please
Explanation:
Compression vs Tension
Tension and compression are two concepts discussed in physics. Tension is a force, while compression is a phenomenon. Both these concepts play important parts in fields such as mechanical systems, automobile engineering, heat engines, material science, pendulums and various other fields. It is vital to have a proper understanding in tension and compression in order to excel in such fields. In this article, we are going to discuss what compression and tension are, their definitions, applications of compression and tension, the similarities between compression and tension and finally, the difference between compression and tension.

When table salt forms, which action occurs between the reacting elements? (1 point)
O Chlorine donates an electron to sodium.
Sodium shares an electron with chlorine. O Sodium donates an electron to chlorine.
O Chlorine exchanges an electron with sodium.
Answer: C: Sodium donates an electron to chlorine.
Explanation:
Sodium wants to lose an electron and chlorine wants to gain an electron to become stable. This is because of their place in the periodic table, sodium being on the very left edge and chlorine on the very right (noble gasses dont count as they are stable to begin with)
Therefore sodium will donate to chlorine so they both become stable with an ionic bond. (another way to tell its ionic is the very large difference in electronegativity)
When table salt forms, sodium donates an electron to chlorine resulting in the formation of bond which is formed when the electronic configurations become stable.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Figure 5 shows how the temperature of a substance changed as it was heated. Which segment of the graph indicates that the substance was undergoing a change of state?
answer:
B
Why:
Because when heated up, the particles vibrate from the heat and keep on vibrating.
at point b of the diagram, the energy is gone to breaking bonds of the (let's assume) solid.
So there is no change in temperature.
I hope this helps please let me know if you need me to explain more.
When temperature is changing with respect to the time in the given graph, then substance B was undergoing a change of state.
What is change of state?When any substance converts from one form of matter to the other form, then this phenomenon is known as change of state.
In the given figure a graph represents the change in temperature of substances A, B, C and D with respect to the time. Temperature of the substances A, C & D keep continuous changing with respect to the time. But substance B shows change in state because it absorbs the heat to convert in another state by breaking old bonds and making new bonds and showing showing no change in temperature.
Hence, substance B was undergoing a change of state.

What is a solvent? please answer
A. The material that is dissolved
B. The material that increases the speed of the dissolution
C. The material that reduces how much can be dissolved
D. The material that is dissolving another material
WILL MARK BRAINLIEST
Answer:
D
Explanation:
Solvent is the material that is dissolving another material. Thus, option D is correct.
A solvent is a substance that dissolves another substance to form a solution. The substance that is being dissolved is called the solute, and the substance that is doing the dissolving is called the solvent. The solute is usually present in a smaller amount than the solvent, and it is the solvent that determines the physical properties of the solution, such as its density, viscosity, and boiling point.
For example, when salt is dissolved in water, the salt is the solute and the water is the solvent. The water molecules surround the salt molecules and break them apart, so that the salt ions are free to move around in the solution. The solution is then a homogeneous mixture of salt ions and water molecules.
Thus, option D is correct.
