In the first video for chapter 29, we looked at the emission spectrum of excited gases. In this video, we look at the __________
Elan Coil [88]

Although the video is not found here, the sentence makes reference to the transmission spectrum of colored filters.

<h3>What is the transmission spectrum?</h3>

The transmission spectrum indicates the light portion having a given wavelength that can be passed through a filter.

This spectrum (transmission spectrum) depends on the physical separation of the particles that form the filter.

In conclusion, although the video is not found here, the sentence makes reference to the transmission spectrum of colored filters.

Two identical loudspeakers 2.30 m apart are emitting sound waves into a room where the speed of sound is 340 m/s. Abby is standi
Dimas [21]

Answer:

Abby is standing (4.5^2 + 2.3^2)^1/2   from the far speaker

D2 = 5.05 m from the far speaker

The difference in distances from the speakers is

5.05 - 4.5 = .55 m     (Let y be wavelength, lambda)

n y = 4.5

(n + 1) y = 5.05 for the speakers to be in phase at smallest wavelength

y = .55 m          subtracting equations

f = v / y = 340 / .55 = 618 / sec     should be the smallest frequency

First, you must know that the statement "<span>An object at rest tends to stay at rest. An object in motion tends to stay in motion unless acted upon by an outside force." is true, because it is the first Law of Newton or inercy law.


what outside force acts on a baseball when it is thrown straight like a pitcher pitching a ball?

After the ball leaves the pitcher's hand, it is subject only to the gravitational attraction of the Earth. That is why the pitcher has to give the appropiate impulse in order to the ball reaches the point that he and the catcher want.

What about if you threw it straight into the air?

It is the same thing. The only force would be the gravitational attraction of the Earth.

What about if you threw the baseball in outer space. Would there be any forces to slow that down?

In outer space, at the beginning the baseball would be very far from of other massive objects to feel their gravitational field, so there would not be any forces to slow it down. Although eventulally, after many light-years, it would enter the gravitational field of a galaxy or other massive body and it would attract it.

Ribosomes are like tiny “factories” within cells that do all of the following EXCEPT:
tensa zangetsu [6.8K]

Answer: translate DNA into RNA <3

Explanation:

An RNA polymerase binds to promoters and then breaks down hydrogen bonds between two strands of the DNA and attaches on one of them. A DNA strand is used as a template for a new RNA molecule. In this way, pre-mRNA is made, which becomes mRNA after the introns are removed.

A mRNA molecule enters the ribosomes, located in the cytoplasm. In these organelles, a transfer RNA attaches to a mRNA and the process of translation begins. The final product is a polypeptide chain.
