Question: which statement provides a complete scientific discription of an object in motion?
Answer: the marble moved 30 cm north in 6 seconds.
Explanation: motion is a change in position of an object over time an object's motion cannot change unless it is acted upon by a force

I believe that the answer to the question provided above is that with increase in resistance provided with constant current, Power dissipated will be lessen since power loss is high. Low power dissipation has low heat production. Hope this helps!! Have a great day!! :)
Answer:
*he force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
*he force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
Explanation:
When a car is going up an inclined plane with constant speed, we can solve the problem using the translational equilibrium equation
Let's locate one axis parallel to the plane and the other perpendicular
F - W x = 0
F = W cos tea
therefore wes ee that the force to climb a plane inlcinado with constant velicad is equal to the cosine of the weight of the body
Work is defined by
W = F. l
in this case the force and displacement are constant
W = F L
where L is the length of the plane
W = mgL cos tes
we see that the work is equal to the cosine of the force times the distance on the plane
<span>In Figure 18.9, the ground wire is first removed, then the rod. This leaves a positive charge on the sphere. If you remove the rod first and then remove the ground wire, there will be no charge left on the sphere. When the rod is removed, the repulsive force caused by the presence of the rubber rod no longer exists. As the wire is still attached, free electrons enter the sphere from the ground until the sphere is neutral again.</span>
