Answer:
Record players
Explanation:
In a record player, a stylus vibrates as it follows a spiral groove cut into the surface of the rotating record.
The vibrations (analogue) are converted into electrical signals and fed into an amplifier to produce the sounds you hear
Fiber optic cables, Wi-Fi devices, and flat screen TVs use digitized signals to encode and transmit information
In the combustion process using excess oxygen, each mole of methane results to 1 mole of co2 while ethane produces 2 moles of Co2. Under same conditions, these can be translated to volume. Hence the total volume absorbed is 10 cm3 + 20 cm3 = 30 cm3.
Answer:
CU
Explanation:
Cu is the correct answer if I'm correct
According to Newton's first law of motion, it takes an unbalanced force to move an object at rest.
I hope this helps :)
Answer:
1. Ionic bonding
2. Covalent bonding
3. Metallic bonding
Explanation:
Ionic bonding also referred to as electrovalent bonding is a kind of chemical bonding that involves the transfer of electrons between the valence shells of two elements with a large electronegativity difference usually a metal and a nonmetal.
For example an ionic bonding scenario might play out between a group one metal and a group seven halogen. While group one metals have one electron hindering their stability, group seven halogens need that one electron that could make them achieve this stability. It is this that causes them to come together in a way where the electron is transferred completely from the valence shell of the group 1 atom and accepted into the valence shell of the group 7 halogen.
Covalent bonding involves the sharing of electrons between atoms of comparable electronegativities. The electro negativity difference is not large enough to permit the total movement of the electrons and hence the electrons are then controlled by the nuclei of the two atoms
Between two metals, what we have is called the metallic bonding
