Answer:
frequency
Explanation:
The number of wavelengths that pass through a fixed point in a second is called the frequency of the wave. It has the unit of Hertz. Hence, option C is correct.
What is frequency ?The term that refers to the number of wavelengths that pass a fixed point in a second is frequency.
Frequency is a fundamental concept in wave motion and is defined as the number of complete cycles of a wave that occur per unit time. For example, the frequency of a sound wave is measured in hertz (Hz) and is equal to the number of sound wave cycles that occur per second.
The higher the frequency of a wave, the more cycles occur in a given period of time. Wavelength, on the other hand, refers to the distance between two adjacent points on a wave that are in phase with each other, such as the distance between two crests or two troughs.
Wavelength and frequency are related, and the frequency of a wave is inversely proportional to its wavelength. As the frequency of a wave increases, its wavelength decreases.
Amplitude refers to the maximum displacement of a wave from its equilibrium position, while compression is a region in a longitudinal wave where the particles are close together. Hence, option C is correct.

what does it mean when you hear science is tentative?
Answer/Explanation:
Tentative means that something is uncertain. So if some aspect of science is described as "tentative" it probably means that there is some evidence to support a hypothesis, but there is more work to be done to be sure about the statements being made.
You may also see these reports described as "preliminary", as they are acknowledging the work is not complete
Placing a sample of iron (II) oxide into a graduated cylinder makes the water volume increase 12.0 ml. The weight of the sample is 76.6g. What is it’s density? (Round to the nearest hundredths)
Answer:
The answer is 6.83 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass of iron (II) oxide = 76.6 g
volume = 12 mL
We have
[tex]density = \frac{76.6}{12} \\ = 6.3833333...[/tex]

where might u find examples of series & parallel circuits in everyday life
Answer: Here are some examples!
Explanation: An example of a series circuit is a string of Christmas lights. If any one of the bulbs is missing or burned out, no current will flow and none of the lights will go on. Parallel circuits are like the smaller blood vessels that branch off from an artery and then connect to a vein to return blood to the heart.

Which mineral is soft enough to be scratched by a fingernail?
a)
corundum
b)
calcite
c)
talc
d)
topaz
Answer:
Talc
Explanation:
Talc only has a hardness of one on the Moh's scale of hardness. This translates into a very soft material, which results from its layered nature. Naturally, this substance is hydrophobic (dislikes water), and tends not to absorb water, therefore giving some of its favourable water-resistant characteristics.
