60
Co-60 is an isotope of Co-59, which is a common component of steel. You get Co-60 by irradiating it with neutrons, so you get Co-60 in nuclear reactors, or anywhere else you have a neutron flux.
0.602
Atomic Mass or mass no
The "60" in Co-60 represents the atomic mass number of the cobalt isotope. It indicates that the cobalt nucleus contains 60 protons and neutrons combined.
Providing that the pole is on level ground you have the outline of a right angled triangle with an adjacent side of 92 ft (the shadow of the pole) and a opposite side of 60 ft (the height of the pole). To find the angle of elevation use the tangent ratio. Tangent = Opposite/Adjacent Tangent = 60/92 = 0.652173913 Tan-1(0.652173913) = 33.11134196 degrees Therefore the angle of elevation is 33o correct to two significant figures.
The mass number of Co-60 is 60. This number represents the total number of protons and neutrons in the nucleus of a cobalt-60 atom.
A cobalt atom with have 27 electrons regardless of the isotope.
A common tangent is a line which is tangent to two (or more) curves.
