B, sedimentary
Fossils are most found in their due to the depth of the rock
This is known as the element IR. (<span>Iridium) Iridium has the atomic number of 77 therefore has </span>
"77 protons, 77 electrons, and 116 neutrons." You can figure out how many protons and electrons a element has by looking at the atomic number. In this case the atomic number is 77 therefore it will have 77 protons and electrons!
Hope this helps!
Given data:
Diameter of the gold wire (d) = 0.175 cm
Length of the gold wire (l) = 1.00 * cm
Volume of the given gold wire = volume occupied by a cylindrical object\
= π * *l
here r = radius of the cross section
where : r = d/2
Hence the volume V = π * *l
=
Density of gold = 19.3 g/cm3
Weight of the gold wire = Density * volume
= *
=
i'm not sure, so sorryyy!
