Answer:

B) Ammonia

Explanation:

Red cabbage juice is an acid-base indicator. It turns red for acidic medium and as the pH increase it turns to violet, green and then yellow.

It means for a basic solution, it would turn yellow. From the given options, coffee and vinegar are acidic. Therefore, they would turn red. Bottled water is neutral. Ammonia is a weak base. It would the indicator yellow.

Light could be thought of as a stream of tiny particles discharged by _______ objects that travel in straight paths. *
Gelneren [198K]

Answer: Light could be thought of as a stream of tiny particles discharged by luminous objects that travel in straight paths.

Explanation:

We can define "radiation" as the transmision of energy trough waves or particles.

Particularly, light is a form of electromagnetic radiation, so the "tiny particles" of light are discharged by a radiating object, particularly we can be more explicit and call it a luminous object, in this way we are being specific about the nature of the radiation of the object.

Sound waves produced by a source pass a point five times every second. Which of the following choices correctly describes the pe
Ugo [173]

The period is 1/5 second, and the frequency is 5 Hz.

Explanation:

Let's start by reviewing some definitions about waves:

- The period of a wave is the time taken for the wave to make one complete cycle. It is indicated with T and it is measured in seconds (s)

- The frequency of a wave is the number of complete cycles made by the wave in one second. It is indicated with f and it is measured in Hertz (Hz). It is equal to the reciprocal of the period:

f=\frac{1}{T}

where f is the frequency and T is the period.

In this problem, we have a wave that passes a given point five time per second. This means that the number of oscillations per second is five, and so its frequency is:

f=\frac{5 cycles}{1 sec}=5 Hz

It follows than the period of the wave is:

T=\frac{1}{f}=\frac{1}{5}s

Therefore, the correct statement is

The period is 1/5 second, and the frequency is 5 Hz.

Explain how fluids exert pressure
Veseljchak [2.6K]
In a fluid, all the forces exerted by the individual particles combine to make up the pressure exerted by the fluid 
Due to fundamental nature of fluids, a fluid cannot remain at rest under the presence of shear stress. However, fluids can exert pressure normal to any contacting surface. If a point in the fluid is thought of as a small cube, then it follows from the principles of equilibrium that the pressure on every side of this unit of fluid must be equal. but if this were not a case, the fluid would move in the directions of the resulting force, So the pressure on a fluid at rest is isotropic.

The table below shows the right ascensions of two stars at a location.
noname [10]
Star 1 - 4 hours right ascension
 Star 2 - 3 hours right ascension
 Subtracting hours right ascension
 4 hours right ascension - 3 hours right ascension = 1 hours right ascension.
Thus,
 star 1 will rise 1 hour before star 2
