How do you measure in centimeters
Answers
Answer:
To measure centimeters, use a ruler with the side marked either cm or mm. Align the edge of the object with the first centimeter line on the ruler, then find the length in whole centimeters, or the larger numbers on the ruler

Balanced chemical equation:
4Fe + 3O2 --> 2Fe2O3
i 2 0.75 0
c 1 0.75 0.5
e 1 0 0.5
Moles Fe = 112g /55.845 = 2
Moles O2 = 24/32 = 0.75
The reaction, with an excess of 1 mol Fe, produced 0.5 moles or 0.5 moles(159.69g/mol) = 79.845 grams of Fe2O3.

Electromagnetic waves best describes the signals sent and received by satellites. Therefore, the correct option is option D.
What is electromagnetic waves?
In classical physics, electromagnetic radiation refers to the movement of energy through a material medium or across empty space at the speed of light in the form of the magnetic and electrical fields that comprise up electromagnetic waves like electromagnetic radiation, visible light, including gamma rays.
Time-varying magnetic and electric fields are linked to one another at right angles or perpendicular towards the direction that of motion in such a wave. The strength and wavelength v of the time fluctuation of the magnetic and electricity fields define an electromagnetic wave. Electromagnetic waves best describes the signals sent and received by satellites.
Therefore, the correct option is option D.

Explanation:
Plasma is a state of matter which is a hot ionized gas and it contains molecules with positive ions and negative electrons.
Since there is high kinetic energy of molecules so, there is swirling gas of positive ions and negative electrons. As a result, there will be release of electrons.
For example, lightening is an example of partially ionized plasma.
Final answer:
When molecules gain significant kinetic energy, their collisions may cause ionization, releasing electrons and forming a plasma, the fourth state of matter. Similar processes can be observed in devices like a Van de Graaff generator or in nature, such as in the sun.
Explanation:
When the kinetic energy of molecules increases significantly, it can cause a phenomenon known as ionization. Energy fueling these molecules increases their pace, effectively leading to collisions among themselves and increasing their speed even more. As these collisions grow in strength, they can cause electrons to be released or ejected, thereby transforming neutral atoms into ions.
Visualize this using the concept of a Van de Graaff generator, which uses a source of positive charge and a moving belt to create a spray of positive charge that achieves high velocities. In conditions of intense kinetic energy, such as those induced by high temperature or light intensity, similar processes occur at the atomic level: atoms, ions, and molecules move and collide, breaking old bonds, forming new ones, and sometimes releasing electrons in the process.
The existence of a gas containing both positively charged ions and negatively charged electrons in this state is often referred to as a plasma. Plasmas are common in extremely hot environments and are considered the fourth state of matter alongside solid, liquid, and gas. Examples of plasmas include the sun and the colorful lights you see in neon signs.
