Shown below is a bond between two elements, X and Y. The direction of the dipole moment is indicated. If neither element
has a formal charge, which of the following statements are true?
Select all that apply.

The picture is an XY bond with the dipole moment going from X to Y

Element Y carries a partial negative charge.

Element Y is more electronegative than element X

Element Y carries no partial charge

Element X is more electronegative than element Y.

Elements X and Y have the same electronegativity

Element X carries a partial positive charge.

Element X carries a partial negative charge.

Element Y carries a partial positive charge

Element X carries no partial charge

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.

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
