Measurement of Young's modulus using sonic resonance
The principal idea behind the sonic resonance test method can be explained using the equation by which one can measure the propagating speed of flexural sonic wave through a medium
(1)
where v is the propagating speed of the flexural wave on a string, F is the tension applied to both sides of the string, P is the mass per unit leng
Pre- Gorbachev Soviet- Vietnames Discord
To answer the aforesaid question, we need evidence, above all, from the vietnamese and Russian archives, but it may also be useful to study the declassified reports of the East European Communist diplomats who were accredited to Hanoi in the 1980s. Namely, the Hungarian diplomats whose reports I read managed to collect an impressive amount of confiden

under study is divided into smaller elements and then analyzed to draw conclusions about the whole. Therefore, content must be reduced to units to measure it.
Content analysis: Key terms
Intercoder reliability: the degree of agreement between or among independent coders.
Why is this needed?
Need some indication that what one person sees in the content, another person will see as well.
