Explanation:
The relationship between work and energy is that work can transfer energy between objects and cause a change in the form of energy.
<h3>What is energy?</h3>
Energy is simply defined as the ability to do work.
Energy possessed by any object or matter enables it to do work of various forms.
Energy can be transferred from one object to another. Also, energy can be transformed into various forms.
Therefore, the relationship between work and energy is that work can transfer energy between objects and cause a change in the form of energy.

Answer:
Therefore, the brick appears to have an additional force pushing it upward.
Explanation:
When a brick is submerged in the water, it has two forces acting upon it. One force is the gravitational force or the weight of the brick, that acts downward. The weight force also acts on the brick when it is not in water. But, in water an additional force acts on the brick. This additional force is named as Buoyant Force. This force is equal to the weight of the water displaced by the brick. And this Buoyant Force acts on the brick in the upward direction. The formula for this force is given as follows:
Buoyant Force = (Density of Water)(Volume of Water Displaced)(g)
<u>Therefore, the brick appears to have an additional force pushing it upward.</u>

Answer:
See the explanation below
Explanation:
In the attached image we can see the free body diagram and forces acting on the book.
Force F, which acts to the right, the friction force which acts in the opposite direction to the movement, i.e. to the left.
The force exerted by the weight of the book that is equal to the product of the mass of the book by the gravity of the book. The normal force that is equal in magnitude to the weight of the book but in the opposite direction.
Answer:
63.36 kJ
Explanation:
Potential energy (PE) is the energy stored within an object, due to the object's position, arrangement or state.
Since the Boulder is now on a height , it has a potential energy
<em>Potential Energy = mass * gravitational acceleration * height</em>
(Assume the gravitational acceleration = 10ms⁻²)
