24. A, natural ph scale for it not to be acidic is 7-8

25. A, not sure about this one

26. A, looked it up

27. A, because it has to be shaken up to make the mixture appear and taste more combined.

28. D, i just guessed

29. D, that answer is stupid so it is the answer because it said not a property

30. A, looked it up

How does a plasma differ from a gas
faltersainse [42]
<span>They are different and unique from the other states of matter. Plasma is different from a gas, because it is made up of groups of positively and negatively charged particles. In neon gas, the electrons are all bound to the nucleus. In neon plasma, the electrons are free to move around the system.

Hope this helps.

What is the difference between a counting loop and an infinite loop?
OlgaM077 [116]
REPETITION CYCLES. A repeating structure allows you to execute an instruction or a set of instructions multiple times. A repetitive execution of sentences is characterized by: The sentence or sentences that are repeated. The cycle is one of the most important basic programming structures, as it is present in dissimilar problems. In structured programming there are three types of basic cycles: determined, indeterminate avoidable, and indeterminate unavoidable; On the other hand, visual programming brings with it a revolutionary change in this structure, since the user who controls when the cycle ends is himself, activating an event that signifies the breaking of the cycle.

What would the speed of this wave be?
valentinak56 [21]

Answer:

c) 100,000 m/s

Explanation:

You need to take the same wave length from the top graph and bottom one, so let's take half a wave length then in the top one that is 0.005, but in the bottom one it's 2000/4 = 500 because they are smaller and there are 4 half waves before you get to 2000, whereas in the top one there is 1 half wave before you get to 0.005 on the graph.

Now use speed = distance / time

speed = 500 / 0.005 = 100 000 m/s

Light of a certain color has a wavelength of 4.8 x 10-7m. Determine the frequency and color of the light wave.
cluponka [151]

The frequency is 6.3\cdot 10^{14} and it is blue light

Explanation:

The relationship between the speed, the frequency and the wavelength of an electromagnetic wave is given by:

c=f \lambda

where

c=3.0\cdot 10^8 m/s is the speed of light

f is the frequency of the wave

\lambda is its wavelength

In this problem, the wavelength of the wave is

\lambda = 4.8\cdot 10^{-7} m

Therefore, its frequency is:

f=\frac{c}{\lambda}=\frac{3.0\cdot 10^8}{4.8\cdot 10^{-7}}=6.3\cdot 10^{14} Hz

The wavelength of this wave is

\lambda = 480 nm

And by looking at the table of the wavelengths of the colors, we notice that this corresponds to the blue light, which has a range of wavelength of

[450 - 495] nm
