Yes that is correct. All waves have wavelength, frequency, REST POINT, and speed. The FREQUENCY of a wave remains constant if the medium, temperature, and pressure do not change.
The above sentence changes to a passive voice, thus:
<em>"Their command of English should have increased considerably if sufficient time and attention were given by students to their work."</em>
The passive voice always follows this pattern: Object + Verb + By Phrase.
When the emphasis is not on the doer but the object of the action, the passive voice is used.
In the above sentence, the passive voice emphasized "their command of English" and "sufficient time and attention," which are objects of the sentence.
Students, who are the doers of the actions, were relegated to the background because the emphasis is not on the doers but the objects of the action.
Thus, the passive voice is always used when the object must be emphasized.

Hey there Carlos!
Let's examine this above.
<span>Jeremy will be planting tulips in the spring.
let's take some key point's from this.
</span><span>Jeremy (will) be (planting) tulips in the spring.
The word's "will" and also "planting" are a form of the future tense.
So, in this case, we can cross out both option (c) and also (d).
Option (c) and also (d) are (present), and the sentence is not present, it would be in the future.
So, now we have both option (a) and also (b) as our last options.
This would be considered a "future perfect progressive" because the sentence shows that "he will plant tulips", which shows that this would be a future perfect goal pretty much.
Hope this helps you Carlos, and if you need any more help, never hesitate to ask more question's on Brainly

The correct option is B.
You can test if there are two independent clauses by separating the clauses and seeing if they can stand alone.
They hadn't planned the trip. They returned to the store the next day and bought more peanut brittle.
Since the the two clauses can stand alone, there are two independent clauses.
Two independent clauses constitute a compound sentence.
Answer: Motivational.
Explanation: This service announcement is directed towards kids. It's trying to encourage and motivate them to conserve energy. You can also use the process of elimination to cross out "aggressive" and "angry." It's not showing any strong emotions either, so it's not emotional.
