I will teach you the procedure and make a calculation, based on a hypothetical dimension.
Call x the length of the side.
You will obtaind two equilateral triangles from a square if you cut by the diagonal.
The length of the diagonal is x√2.
If the sign is placed with the diagonal as the base and the vertex up (this is the righ angle), then the heigth is half the diagonal, i.e. (x√2) / 2.
So, if the side of the square is 100 inches, the diagonal is 100√2 and half diagonal is 50√2, which to the nearest tenth is 70,7 in.
Correct question:
Which reaction describes a beta emission? 2659Fe→ 2759Co + −10e, 88226Ra→ 86222Rn + 24He, 94239Pu + 24He→ 96242Cm + 01n, 54118Xe→ 53118I + +10e
Answer:
2659Fe→ 2759Co + 1e
Step-by-step explanation:
General equation for beta decay is given as;
where;
A is the atomic mass of the element
z is atomic number of the element
X is the parent atom
Y is the daughter element
β is beta emission
In beta emission, there is loss of one electron and zero proton, the will cause the daughter element to gain on electron in order to balance the reaction.
Based on beta decay equation above, we select the reaction that describes beta emission.
2659Fe→ 2759Co + 1e
Here;
A = 59
z = 26
z + 1 = 27
