Evaluate skill performance against a scale is known as Rubrics; option D
<h3>What is performance evaluation?</h3>
Performance evaluation is the systematic process of assessing the performance of an individual in a certain task, skill or job.
Performance evaluation is done against a set of standard measurements or a rating scale known as Rubrics.
Rubrics use a set of specific criteria to evaluate an individual student or a group of students performance in a certain task assigned to them.
Rubrics use a rating system where points or scores are awarded depending on the skillset level or ability demonstrated.
In conclusion, rubrics are used to evaluate performance.

A vacuum tube consists of cathode (also called as filament), anode (also called as plate), and electrode (also called as grid). Cathode is an electron emitter that emits the free electrons whereas anode is an electron collector that collects the free electrons.
I hope this helps.
Time needed = t = 20.83 s
<h3>Further explanation</h3>
Given
car speed = 85 km/h
truck speed = 73 km/h
Required
the time it takes for the car to reach the truck
Solution
When the car reaches the truck, the distance between them will be the same
x car - 250 m = x truck
General formula for distance (d) :
d = v.t
So the equation becomes :
85t-250 = 73t
12t=250
t = 20.83 s
Answer:
Surface tension
Explanation:
When liquid rises against gravity in a capillary tube, the energy comes from surface tension.
This is because surface tension is the energy that's needed to increase the liquid surface area.
As a result of hydrogen bonding present in Water, it usually has high surface tension which makes it to possess a tough skin that can make it not to break despite high forces applied to it.
The liquid will be in contact with the capillary tube and as such experiences surface tension which in turn makes the capillary tube to experience an upward force that makes the liquid begin to rise up.
The more the liquid keeps rising, the more it gets to the point where the surface tension becomes balanced from the weight of the liquid.
