marysya [2.9K]

Answer:

               The type of bond formed in FeS would be <u>Polar Covalent Bond</u>.

Explanation:

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

               Less than 0.4 then it is Non Polar Covalent  Bond

               Between 0.4 and 1.7 then it is Polar Covalent  Bond

               Greater than 1.7 then it is Ionic  Bond

For Fe and S,

                   E.N of Sulfur           =   2.58

                   E.N of Iron              =   1.83

                                                  ________

                   E.N Difference            0.75          (Polar Covalent Bond)

Find the average speed of a person who swims 105 m in 70 s
spin [16.1K]

Answer:

v = 1.5 m/s

Explanation:

Given that,

Distance covered by a person, d = 105 m

Time taken, t = 70 s

We need to find the average speed of the person. We know that the average speed is given by :

v=\dfrac{d}{t}\\\\v=\dfrac{105\ m}{70\ s}\\\\v=1.5\ m/s

So, the average speed of the person is equal to 1.5 m/s.
