Answer:
An alloy is the combination of metals homogeneously.
Explanation:
Alloys can also include other elements in combination with metals e.g carbon and Iron forms steel.
Alloys find a host of application in various industries and domestic use.
Alloying of metals helps to improve the physical and chemical properties of such materials better.
Some materials are alloyed to improve their strength.
Alloying can help heat and electrical conduction of a substance.
Alloys can greatly prevent rusting and produce corrosion resistant metals.
Alloys can provide a better means for a material to be worked.
Alloys can be more durable than original materials.
Answer:
(4) The navy needed a faster way to move ships between the Atlantic and Pacific Oceans.
Explanation:
The Panama Canal was an artificial eighty-two (82) kilometers water-way that connects the Atlantic Ocean with the Pacific Ocean in Panama and it enhanced maritime trades.
The construction of the Panama Canal became more important to the United States after the Spanish-American War because the navy needed a faster way to move ships
between the Atlantic and Pacific Oceans.
Answer:
A. Reference blank
B. Cuvettes
C. Transmittance
D. Absorbance
E. Wavelength
Explanation:
A reference blank is a sample prepared using the solvent and any other chemicals in the sample solutions, but not the absorbing substance.
A square-shaped container, typically made of quartz, designed to hold samples in a spectrophotometer is known as Cuvettes.
A measurement of the amount of light that passes through a sample or percentage of light transmitted by the sample, with the respective intensities of the incident and transmitted beams is called Transmittance.
The measurement of the amount of light taken in by a sample is known as Absorbance
The wavelength is also the distance travelled by the wave during a period of oscillation. In spectrophotometry, the unit is inversely proportional to energy and commonly measured in nanometers
Answer:
The human body is composed of the different systems or controlling parts, and among these organs the brain and spinal cord functions for the regulation of nerves and for the regulation of communication inside the human body. As, there are small basic units or cells called as neurons which makes up the basic framework for the functioning of this nervous system.
- Now, each of our body's function is either voluntary or involuntary in nature. As, they arise to having a chemical imbalance or in other words a synapse inside the structure or body of the neurons. While, all of the actions are full controlled by the central nervous system but some of them are controlled by the processing system which are called as the voluntary changes or actions. And on the other those which are not controlled all by the human body, as such actions are said to be involuntary in nature.
- While, the nervous system outside the more organized and becomes more complex when we analyze the nervous system outside the CNS and such neural system is then termed as the peripheral nervous system.
- Some of the response are quick and do not require any longer for the body to react in and such body responses are termed as the autonomic fight-or-flight responses. As, such functions or changes inside the body posture and system included inside the sympathetic relaxing responses.
