<h3><u>Answer;</u></h3>

C) Covalent bonds are generally weaker than ionic bonds because they overlap electrons to fill their outer shell.

<h3><u>Explanation;</u></h3>

<em><u>Covalent bond is a type of bond that results from the sharing of electrons between two non-metal atoms. </u></em>
<em><u>Ionic bond on the other is a type of bond that results from the transfer of electrons between metal atoms and non metal atoms, where a metal atom looses electrons and a non-metal atom gains electrons.</u></em>
<em><u>The amount of energy required to break an given bond determines how strong a particular bond is.</u></em> Ionic bonds require more energy to break as compared to covalent bond and therefore they are stronger than the covalent bonds.

Answer:

Kf = 470 mJ

Explanation:

According the work-energy theorem, the change in the kinetic energy of one object, is equal to the net work done on it.
Since the puck is initially at rest, the change is kinetic energy is just the final kinetic energy of the puck.
Assuming that the net force is horizontal, and causes a horizontal displacement also, we can find the net work on the puck as follows:

$W_{net} = F_{net} * \Delta X = 0.56 N * 0.84 m = 0.47 J = 470 mJ (1)$

The dummy's acceleration is 11 m/s^2
(also known as 11 meters per sec. per sec.)

a = F/m
= 825 N/75 kg
= 11 m/s^2
