Let us reject some answers. AM and FM radio waves do not interfere. Am are an orders of magnitude larger than FM waves. FM waves belong to microwaves, a subcategory of radiowaves while AM does not. Similarly, AM and TV have not the same, because TV uses a subset of the frequencies used in FM. The correct answe is that CB radios and submarine communication happen at the same wavelengths/frequencies, namely low frequency radiowaves.
Answer:Geography, Earth Science, Astronomy
Rotation describes the circular motion of an object around its center.
Explanation:
Answer:
velocity 1 second later = 59.8 m/s
Explanation:
Velocity final = Velocity initial + acceleration • time
Velocity final = 50m/s + 9.8m/s/s • 1s
Velocity final = 59.8 m/s
Friction produces heat hope this helps
In contrast to the heat that is still being actively produced by radioactive decay, primordial heat is the heat that the Earth loses as it continues to cool following its initial development.
Primordial and radiogenic heat can be found in the earth's deep core. Radiogenic heat is the thermal energy released as a result of spontaneous nuclear fusion, whereas primordial heat is the internal heat energy built up by planets during their first few million years of evolution.
The internal heat energy that a planet has built up over the course of its first few million years of evolution is known as primordial heat. The energy deposited by falling planetesimals, known as accretion energy, and differentiation energy, are the main sources of the primordial heat.
