Answer:
Explanation:
Given
Initial Form: Onyx
Final Form: Rectangular Solid
Dimension of Solid = 5.10 cm by 5.10 cm by 2.50 mm
Required
Volume of the solid (in cm³)
The volume of a solid is calculated as thus;
Assume the following;
The first thing to do is to convert the assumed height from mm to cm
Given that;
This implies that
Hence, the dimension of the solid in cm is:
The Volume is then calculated as;
Hence, the volume of the rectangular solid is
Answer:
half-life=T= 36.9 years

after a certain time=t=184.5 years
T=half life of a nuclide=?
Putting value in above equation we get
half-life=T= 36.9 years

There are three measures of retrieval and forgetting, bear in mind, the degree to which a person brings found facts back to conscious cognizance; recognition.
A measure in which someone identifies previously discovered statistics; and relearning, a measure wherein a person is asked to learn facts at a time. There are five popular theories of forgetting in psychology. they are the hint decay principle, retrieval failure idea, interference theory, consolidation concept, and displacement idea.
In keeping with retrieval-failure theory, forgetting happens whilst statistics are available in LTM but aren't accessible. Accessibility relies upon in massive part on retrieval cues. Forgetting is finest whilst context and country are very one-of-a-kind at encoding and retrieval.
