Use the periodic table to explore the electronegativities of elements from Period 3 and
Group 17. Fill in the missing values in the table so
you can compare the electronegativities of the
elements. After the table is filled in, compare the
values in each column.

C=

A= 3.16

B= 1.31

C= 0.93

Explanation:

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
