Answer:
Earth Day is observed globally
Explanation:
The force applied to pull the box up the ramp acts parallel to the incline is 8N
The force applied to pull the box is expressed as:
Fm is the moving force
Ff is the force of friction
Get the moving force and frictional fice
The force applied to pull the box up the ramp acts parallel to the incline = 5N + 3N = 8N
Hence the force applied to pull the box up the ramp acts parallel to the incline is 8N

Answer: B. Gravitational potential energy </h2>
Explanation:
<em>The gravitational potential energy is the energy that a body or object possesses, due to its position in a gravitational field.
</em>
That is why this energy depends on the relative height of an object with respect to some point of reference and associated with the gravitational force.
In the case of the <u>Earth</u>, in which <u>the gravitational field is considered constant</u>, the value of the gravitational potential energy will be:
Where is the mass of the object, the acceleration due gravity and the height of the object.
As we can see, the value of is directly proportional to the height.
Answer:
3.75 J
Explanation:
m = 1.5 kg
a = 0.5 m/ s^2
d = 5 m
w = F × d = (0.5×1.5) × 5 = 3.75 J
