A mass of 2 kg is suspended from the rod at 20 cm and another unknown mass'm'is suspended from the rod at 160 cm mark as shown in the figure. Find the value of 'm' such that the rod is in equilibrium. (g= 10 m/s2) 1)1/2 kg2) 1/3 kg3)1/6 kg4) 1/12 kg​

Answer:

55

Explanation:

Answer:

The atomic mass of Mn is 55.

Explanation:

Mn is the chemical representation of the Manganese element.

Manganese is a chemical element( atomic number 25 and the symbol Mn). It's a hard, brittle silvery metal that's frequently seen in minerals with iron. Manganese is a transition metal that has a wide range of industrial alloy applications, especially in stainless steel.

The actual atomic mass of Mn is 54.938044 g/mol.

31.4/6.28.

we have to divide with 2.

It is 15.7/3.14.

It will will no divide further more.

Sodium forms Na+ ion but it doesn't form Na+ because of. (A) Very low value of first and second I.E. (B) Very high value of first and second I.E. ... Hint: The ionization energy is defined as the energy required to remove an electron from the outermost shell of a nucleus.

Answer:

Answer: Na has the electronic configuration 2,8,1.

Sodium will never have a charge of 2+ as it does not have 2 valence electrons that it wants to Jessica's to be stable.

Therefore, Na readily forms Na+ ,but not Na2+.
