What type of antenna where Penzias and Wilson testing in 1962 that led to their discovery of one of the biggest piece
of evidence supporting the Big Bang Theory

Answers

Answer 1

In 1964, Bell Labs scientists Arno Penzias and Robert A. Wilson were conducting experiments with the Holmdel Horn Antenna, an extremely sensitive device originally used to detect radio waves that were bounced off Echo balloon satellites, and later Telstar, the first active communications satellite. These radio waves were so weak, that it became critical to eliminate all possible interference in order to detect them.

Despite taking all conceivable steps to eliminate interference, they continually detected a strange, buzzing noise that was coming from all parts of the sky at all times of day and night. They did a range of additional testing on the equipment, and even removed some pigeons that were nesting in the antenna and their associate detritus. Still, the sound persisted. They ultimately determined that the noise was coming from outside of our galaxy

Almost by chance, they later learned that researchers and astrophysicists Robert H. Dicke, Jim Peebles and David Wilkinson at nearby Princeton University were looking for a way to detect residual radiation that they believed would have resulted from the Big Bang. As it turned out, the radiation detected by Penzias and Wilson was a perfect match for what the Princeton researchers had predicted, and hence made history.

Arno Penzias (left), Robert Wilson (center) and Keith Jefferts (right) look through a model of the universe to the constellation Orion where, for the first time, they discovered carbon monoxide in outer space.

From the archives

An audio recording of the CMBR noise was captured and narrated by Robert A. Wilson. This discovery in 1964 by Penzias and Wilson, announced in a Bell Labs press release, earned the researchers a Nobel Prize in Physics and provided the basis for future astronomical discoveries.

Explanation:

Answer:

B. a group of connected or related things?

Explanation:

A system must have some form of relationship between the components inside of it. All these components work together to do a certain task or to run efficiently.

For example, let's take the court justice system. Inside the system is broken down into a range that can go from small claims court to the Supreme Court of the United States. This system is to ensure that their is not only a smaller burden on the supreme court to be able to take care more of national & international claims, but also so that if a citizen feel that they have a unfair ruling, they may bring it up to a different court that may not have local preferential to a certain degree.

All parts of a system is connected or related to each other, either as a cause, and effect, or a solution.

Describe two practical uses for an artificial chemical which behaves like chlorophyll.​

Answers

Any substance that has enhanced reactivity, or altered properties in the presence of light is said to be photoreactive. For example, a photovoltaic cell enables sunlight to be processed into usable electricity by exciting outer shell electrons on some metals. Photoreactive substances can either be natural, such as chlorophyll, or entirely man-made in the case of a photovoltaic cell.

Chemicals like Titanium dioxide and photovoltaic cells are artificial chemicals that behave like chlorophyll.

What do you mean by Artificial chemicals?

Artificial chemicals may be defined as chemicals that are synthesized by the activity of humans and their processes.

The nanoparticles of titanium dioxide have the ability to increase the light-capturing potential of a surface, while a photovoltaic cell enables sunlight to be processed into usable electricity by exciting outer shell electrons on some metals. These substances also behave naturally and initiate the reactions in the reaction center present in the chloroplast.

Therefore, Chemicals like Titanium dioxide and photovoltaic cells are artificial chemicals that behave like chlorophyll functionally.

It takes just four hours for one bacterium to become _____.

Answers

Answer: 256 bacterium.

Explanation:

suppose a bacterium would divide once in every half an hour, this means it would be double in half an hour.

therefore, a number of the bacterium after half an hour will be 1 x 2 = 2.

After one hour, we would have doubled the number of bacterium =2 x 2

= 4.

Also, in one and a half hours, it would become 4 x 2

= 8.

In 2 hours, it would be 8 x 2 = 16.

Also in two and half hours, it would  be 16 x 2

= 32.

In three hours, it would be 32 x 2

= 64.

In three and a half hours, it would be 64 x 2

= 128.

Funally, in four hours, the number of bacterium would have been multiplied to 128 x 2

= 256.

It takes just four hours for one bacterium to become 256 bacteria.

It should be noted that a bacterium will divide once in every half an hour. This implies that it'll be double in every half hour. Therefore, for an hour, there'll be 2 bacterium.

Since it doubles every half hour, in 2 hours, the value will be 16 bacteria. Therefore, the value in four hours will simply be:

= 16 × 16 = 256 bacterium.

Therefore, it takes just four hours for one bacterium to become 256 bacteria.
