Higher frequencies, typically above 20 MHz, would result in the greatest ultrasonic attenuation losses in materials due to increased scattering and absorption.
Anthracite coal likely formed from the greatest pressure, as it is the highest grade of coal and has undergone the most intense metamorphism.
Albert Einstein's greatest discovery is probably the theory of relativity. This theory revolutionized our understanding of space, time, and gravity, leading to breakthroughs in physics and shaping many scientific advancements in the 20th century.
The object with the greatest mass is probably a supermassive black hole located in the center of a galaxy, such as the one in the Milky Way galaxy. These black holes are believed to have masses equivalent to millions or even billions of times the mass of our sun.
The forces of gravity that attract the Earth and an object on its surface toward each other are greatest for the object with the greatest mass. Among the items on your list, that's probably the house.
Gamma radiation is an extremely high frequency EM wave and is probably the common lightwave with the highest energy. Since energy is proportional to frequency, the highest energy wave would be that with the highest frequency.
the battle of stalingrad would probably be the greatest defeat.
War
Yes, probably
SETI listens to frequencies between 1420 (the Hydrogen molecule) and 1662 (the hydroxyl molecule). This is to say that an intelligent civilization would recognize these frequencies and would probably be monitoring them a well. The cosmos is full of these frequencies and a slight deviation in the regular pulsing of these frequencies would be noticed by anyone who is scanning the skies. Hope this helps. Sam Farina III
Probably the greatest: she was a wife and a mother.
Probably the Internet
A talented President
Probably the four seasons
To summarize an NIH article, probably not. They did research on musculoskeletal disorders and found that use of ultrasonic therapy was only statistically significant in one of the disorders-- where they will do a further study. But, it's not with out some basis in fact. Ultrasonic shock waves are used to break up kidney stones-- so it does have an effect in some diseases. But, probably only those systems large enough to be in a major hospital.
For immediate impact, probably nuclear. For total impact, probably biological.
There is no bond specified. Probably the one with the greatest maturity.
The war was probably the greatest influence.
