Answer 1

Answer:

B

Explanation:

Experiment tools and methods were not as precise as they are now. Since tech has evolved so has the ways to look at atoms meaning that they will see new and different things.

Answer 2

This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence. And  Because more experiments gave more data, theories and models for atoms changed to be more accurate over time.

Snow slides down a mountain in an avalanche. Where would the snow have the
most potential energy?

Answers

Answer:

At the top of the mountain

Explanation:

The snow will have the most potential energy at the top of the mountain. Potential energy is the energy at rest of a body. It is a function of the mass, acceleration due to gravity and height of the body.

                              P.E = mgh

Since at the top of the mountain, we have the highest elevation. So, we expect that at the peak of the mountain the potential energy will be highest here.

Which best explains why the sun maintains its size and shape?
A. Pressure caused by high temperatures are balanced by gravity.
B. The sun burns from its core to its surface.
о
C. Forces exerted by orbiting planets cause the sun to rotate.

Answers

Answer:

A

Explanation:

The Suns own weight keeps itself together and keeps its size and shape. all things have gravity. in this case, the sun keeps it shape with balancing its gravity with the pressure.

The best explanation of why the sun maintains its size and shape is forces exerted by orbiting planets cause the sun to rotate. The correct option is C.

What is orbiting?

"Orbiting" is one of those digital dating terms that perfectly describes what many of us have experienced but didn't realize had a name. It's when someone you were dating tells you they're no longer interested but keeps in touch with you on social media.

The Sun's own weight holds it together and maintains its size and shape. Everything has gravity. In this example, the sun maintains its shape by balancing gravity and pressure.

Planets orbit the sun in elliptical orbits, with the sun slightly off-center of each ellipse.

Therefore, the correct option is C. Forces exerted by orbiting planets cause the sun to rotate.

explain what safety measures you might take to avoid damaging the microscope, microscope slide, or a living specimen on your microscope stage​

Answers

Answer:

Some of the safety measures one can take to prevent damage to the microscope, microscope slide or living specimen include;

1. Always carry the microscope with two hands

2. Do not touch the microscope lens

3. Clean and store properly after using

Explanation:

1. Microscopes are delicate laboratory equipments and hence, should be handled with care. The proper way to handle or carry a microscope is to place one hand on the arm and the other below the base of the microscope. This will prevent the microscope from hitting something and getting damaged or something falling off.

2. The lens, either the objective or occular, is what makes visibility of any specimen possible. It shouldn't be mishandled by touching it or using inappropriate materials to clean it. A lens cleanser designed for that function should be used.

3. After use, the microscope should be cleaned thoroughly and stored in a dry place. The maintenance of the microscope will improve how long it will last.

The equipments used in the science laboratories require proper handling and safety measures to help the students and researchers to prevent any kind of illness and injury.  

• The following are the safety tips to follow to avoid damaging the microscope, a living specimen on the microscope stage, or a microscope slide:  

• One should use the microscope with two hands and should wear proper lab clothing.  

• One should look at the specimen from the side, not via the eyepiece at the time of turning the low power objective as close as possible to the specimen at the time of the initiation of observations.  

• One should avoid the application of coarse adjustment knob at the time of using the high power objective.  

• One should prevent turning the fine adjustment knob more than a fourth turn to amend the focus at the time of using the high power objective.  

Thus, one should follow precautionary measures while handling microscope and its components.

The Beach Boys were an influential surf rock band, filled with guitars and harmonies. Their leader, Brian Wilson, rose up as one of the most significant, original musicians and composers of 20th-century popular music. In the early 1960s, Brian formed the band the Beach Boys with his brothers Dennis and Carl, his cousin Mike Love, and their school friend, Al Jardine. He wrote many of the band's songs, launching the group into stardom and celebrating the surf culture's fascination with fun in the sun. He was responsible for such hit songs as Help Me, Rhonda and Surfin' USA. Even though he became deaf in one ear, he continued to arrange and compose most of the Beach Boys' songs, which were flooded with harmonies and interesting chord progressions that weren't normally heard in pop music. Brian Wilson was also admired by the Beatles, though he viewed that band as competition. Wilson was a perfectionist, always wanting his music to be absolutely perfect, which sometimes caused stress in the group. His desire to be perfect led him to become very depressed in the 1970s. He was able to get back up on his feet after receiving counseling, along with the love and support of family and friends. Continuing to write music, he finished projects that were left unfinished and impressed audiences yet again with his unique orchestral songs. In 1988, Brian Wilson overcame difficulties and released a solo album. He also released some music that he had once written for the Beach Boys, but that they never produced. He showed that he hadn't lost his touch as a singer and unbelievably talented songwriter.Which of the following best describes Brian Wilson?A.) He was completely deaf and yet still wrote impressive, harmonious music for audiences.B.) He was an important songwriter and musician in the band the Beatles.C.) He was a member of the band the Beach Boys with his brothers Dennis and Carl.D.)He was very influential in the world of pop music.
