The fulcrum is the point in any mechanical device where the moment due to weights is zero.
(Weight 1 x distance 1) - (weight 2 x distance 2) = 0
(1.7 Kg x 1.5 m ) - (weight 2 x 1.2 m) = 0
weight 2 = (1.7 Kg x 1.5 m ) / 1.2 m
= 2.1 Kg

Answer:
1)Manganese (Mn)
2)Sulfur(S)
Explanation:
Atoms of which element contain 25 protons?
It is Manganese.
The atomic number of an element is the number of proton in the nucleous of an atom of the element. Here proton= 25= atomic number.
The number of proton helps to identify the particular element. In the modern periodic table, the elements are arrange base on how the atomic number is increasing. Then Manganese has atomic number of 25.
✓Which element has an atomic number of 16?
It is Sulfur, as explained earlier, the number of pron in the atom of the sulfur element is 16.
