REY [17]2 years ago

4 0

Explanation:

Molybdenum is a chemical element. It is denoted by Mo. In this problem, we need to match the phrases with their corresponding values using periodic table.

Atomic no = 42

Atomic mass = 95.94 amu or 96

No of valance electrons = The elctronic configration of Molybdenum is [Kr] 4d⁵ 5s¹. It means there is 1 valance electron in it.

No of electrons in the n = 3 shell = 18

No of neutrons = 54

Westkost [7]

Answer:

-5.8868501529 m/s² or -5.8868501529g

0.118909090909 s

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 9.81 m/s²

$v^2-u^2=2as\\\Rightarrow a=\dfrac{v^2-u^2}{2s}\\\Rightarrow a=\dfrac{1.3^2-2^2}{2\times 0.02}\\\Rightarrow a=-5.8868501529\ m/s^2$

Dividing by g

$\dfrac{a}{g}=\dfrac{-57.75}{9.81}\\\Rightarrow a=-5.8868501529g$

The acceleration is -5.8868501529 m/s² or -5.8868501529g

$v=u+at\\\Rightarrow t=\dfrac{v-u}{a}\\\Rightarrow t=\dfrac{1.3-2}{-5.8868501529}\\\Rightarrow t=0.118909090909\ s$

The time taken is 0.118909090909 s
