Answer:
The number, such as 98.7 FM, of a radio station represents:
- <u>the frequency in which is transmitted the radio signal</u>.
Explanation:
<em>The radio FM is the modulated frequency, which means that all the information is sent by just a signal, with different frequencies which difference them</em>, <u>the radio FM use the frequencies from 88 MHz until 108 Mhz (MHz is a measuring unit for the frequency), with a minimal space among them of 0.2 MHz</u>, this last means that you could find a signal in 88.0 MHz, and the next should be 88.2 MHz, next 88.4 MHz and so (at least, regularly the space between two frequencies is more than 0.2 MHz).
Answer:
3- is the charge and 8 dots on its Lewis dot structure.
Explanation:
Hello there!
In this case, since nitrogen is an element with five valence electrons (electrons on its outer shell), we infer that it needs three bonds to complete the octet, for which its charge, when forming nitride ions is 3-, which means it has received three electrons. Thus, when drawing the Lewis dot structure, it is evident that is will have 5+3 = 8 dots due to the electron reception.
Regards!
Question:
Layer 1 and 2 → Animal fossil
Layer 3 and 4 → First plant fossil
Layer 5 → Animal fossil
Layer 6→ Second plant fossil
Layer 7 → Animal fossil.
Answer:
The correct option to choose answer is;
C) Layers 3 and 4 (Secondary succession layer).
Explanation:
Secondary succession is a concept related to pliant life and it describes the notion of an ecosystem regenerates after being destroyed and it takes place when the level of disruption is not enough to do away with all present vegetation and present soil from a location.
Secondary succession is started by an incident that destroys to a large extent the present ecosystem. Events that start secondary succession includes;
1) Hurricane
2) Fire and
3) Harvesting.
The equivalence point of a titration is equal to its stoichiometric equivalents of analyte and titrant.
Depending on the concentration of titrant we could be adding little excess of it and this may result in persistence of color of solution. After continuous stirring for a while the excess titrant may react with dissolved CO₂ in air and thus decolorizing the solution.
