The type of Nuclear decay that is described where Gold undergoes transmutation is given as 185/79 Au → 181/77 Ir + 4/2 He, it is called Alpha Decay.
<h3>
What are the characteristics of Alpha Decay?</h3>
An Alpha Decay can be described as a form of radioactive or Nuclear decay where the atomic nucleus releases an alpha particle (also known as Helium Nucleus).
It then converts into a nucleus that is atomic with an atomic number of two and a mass number of four.
Alpha Decay is usually trigged for two key reasons:
- An unstable nucleus; and
- excessive protons.

If 64 is a perfect cube the length of each edge of the block can be found. The edge length of a cube is: 4cm.
<h3>Edge length of a cube</h3>
Given:
Volume of cube=64cm³
Hence:
Volume of the cube = a³
Volume of the cube, a³= 64 cm³
Using this formula
Cube edge length =∛(side)³
Let plug in the formula
Cube edge length =∛(64cm³)
Cube edge length=4cm
Therefore if 64 is a perfect cube the length of each edge of the block can be found. The edge length of a cube is: 4cm.

The point M is the bisector of the line RS
<h3>Bisector of a line</h3>
A bisector is a point or line that divides another line or segment into two equal parts
A line is the shortest distance between two points. From the line given, there are 3 points on the line which are R, M and S. Since the point M is located in the middle of RS, hence the point M is the bisector of the line RS
