Answer:

the only way to change the velocity of an object is to apply force.

Explanation:

Newton’s first law of motion says an object will continue to move with the same velocity unless acted on by an external force.

The sound of a flute is poetic, light, mellow, and soft. Flute is a woodwind musical instrument produces the mild sound.

Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as solid, liquid ang gases. When an object vibrates, it causes a movement in surrounding air molecules. The molecules collide with the molecules close to them, causing them to vibrating as well.

The sound from flute comes due to the vibrating columns of air inside it. In a flute, the air gets vibrated and the resonator amplifies the vibration and gets modified into sound. When air is blown into the holes of flute, it creates the vibration in the air molecules inside the flute and hence, sound is produced.

The flute can produced continuous sound by the presence of number of holes in it. The flute sounds may be high pitch or soft tone depends on the position of upper and lower lips on flute.The sounds of flute are rich, gentle and gracefull.

2. isolation of the gene of interest;

3. amplifying the gene to produce many copies;

4. associating the gene with an appropriate promoter and poly A sequence and insertion into plasmids;

5. multiplying the plasmid in bacteria and recovering the cloned construct for injection;

6. transference of the construct into the recipient tissue, usually fertilized eggs;

7. integration of gene into recipient genome;

8. expression of gene in recipient genome; and

Explanation:

Cancer is the name given to a collection of related diseases. Cancer is more than one type of disease. In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation. CAD, Stroke, Respiratory illness, COPD are all diseases related to cancer. Inherited genetic mutations play a major role in about 5 to 10 percent of all cancers. There are many environmental pathogenic factors that can cause cancer. For example , Tar and Coal-Tar Pitch , Emissions , Secondhand Tobacco Smoke (Environmental Tobacco Smoke) , Arsenic , Soot , Asbestos , Wood Dust. When cancer cells break away from a tumor, they can travel to other parts of the body through the bloodstream or the lymph system. Cancer is hard to treat in later stages because it probably has already spread through out the body. The grade of a cancer depends on what the cells look like under a microscope. In general, a lower grade indicates a slower-growing cancer and a higher grade indicates a faster-growing one. Some examples of cancer treatments of cancer are, Surgery, Chemotherapy, Radiotherapy, Cancer drugs, Hormone therapy, Stem cell and bone marrow transplants, Targeted cancer drugs. A new treatment involving a photosensitising agent that makes cells more sensitive to light and, by doing so, causes cancer cells to be destroyed when a laser light is directed on a cancerous area. One challenge is, druggable genomic alterations are diverse and represent only small subsets of patients in certain tumor types, which limits testing their clinical impact in biomarker-driven clinical trials. Next-generation sequencing technologies are increasingly being implemented for molecular prescreening in clinical research, but issues regarding clinical interpretation of large genomic data make their wide clinical use difficult.

The type of heat transfer that is most important to maintaining a relatively stable climate on Earth is known as solar radiation.

Heat transfer may be characterized as the migration or transmission of heat across the border of the system due to an imbalance of difference in temperature between the system and its surroundings.

Solar radiations govern the principle and the entire process of heat transfer because it is the principle and fundamental source of heat and energy for the entire planet of the earth. These radiations initiate the process and pass down to the source artificial sources of heat transfer in physical life.

Therefore, solar radiation is a type of heat transfer that is most important to maintaining a relatively stable climate on Earth.

So basically, the first image shows a magnetic force created by the magnetism. This attracts/pushes away other magnets. The second picture is showing two magnets being held together while they are trying to push away from each other. The third picture is demonstrating the release of the magnets. As soon as you let go, the magnets push away from each other. I think the PE and KE are like models of batteries. PE is potential energy, being dormant until released. KE is kinetic energy, the energy that depends on the motion of the object. The more energy used, the more you fill in the battery. I hope this helps!

Thus, Since the turn of the 20th century, glass has been made with calcium fluoride, a novel substance. It is a solid that dissolves readily in water and has a special physical and chemical makeup that makes it suitable for usage as a glassmaking material.

Glass used in windows, bottles, and other glass goods was formerly created from calcium silicates before the invention of this substance. The new glass, referred to as glass with added fluorides, has a number of advantages over calcium silicates, which have drawbacks that make them unsuitable for the creation of modern glass.

Calcium Fluorine is a naturally occurring element that is frequently found in rock, soil, plants, and animals.

We use the four properties of sound: pitch, dynamics (loudness or softness), timbre (tone color), and duration.

Answer:

Dynamics, Duration, Pitch, Timbre! Hope this helped

Explanation:

1: Equilibrium

[] When two forces are equal in opposite directions, they are in a state of equilibrium

2: Friction

[] It can be hard to sometimes slide a paper across a table, roll a car across the ground, etc etc. This is because of a force called friction which resists motion

3: Displacement

[] Work is only "done" when the object or surroundings are having movement, or in motion, and this creates displacement

4: Force

[] A force is a push/pull in any direction, this is a simple definition so not much can be added.

5: Inertia

[] Inertia is a force that likes to remain unchanged, or without movement

6: Effort

[] "Meg is holding up weight without movement. She hasn't done any work since it did not move, but is tired. Why?" Effort! She still put in effort even though no "work" happened

7: Work

[] Force times displacement is the equation for work

8: Motion

[] Look back to #3, when there is motion we can tell work is done
