Explanation:
Cell phones are widely used by people all over the world as a medium of communication. When a person makes a call from a cell phone, the cell phone emits electromagnetic waves that are intercepted by a nearby cell phone tower. The cell phone tower then connects the call to the phone of the person being called.
Which of the following processes enables a cell phone to receive communications from a cell phone tower?
A.
Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.
B.
Electromagnetic waves from the tower are reflected by the cell phone, producing an electromagnetic field that is detected by the internal circuits of the phone.
C.
Electromagnetic waves diffract around the cell phone's antenna, which allows the waves to be detected by the internal circuits of the phone.
D.
Electromagnetic waves from the tower interfere with the radio waves emitted by the cell phone, producing electric currents in the internal circuits of the phone.
Answer:
A Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.
Explanation:
Its correct I just did it
The correct option is A which is when a cell phone's antenna picks up electromagnetic waves from a tower, the phone's internal circuit becomes electrically charged through which communication is enabled.
How does a cell phone receive communications from a cell phone tower?Radio waves are sent by mobile phones through a base station network, which is a collection of permanent antennas. Since radiofrequency waves are electromagnetic fields rather than ionising radiation like X-rays or gamma rays, they cannot ionise or destroy chemical bonds in living organisms.
A cell tower has several antennas linked to it, usually positioned on a head frame. Even more than 15 antennas per carrier are found on some towers. This figure largely depends on the performance, area of coverage, and capacity needs of the antenna.
Effect of 5G on health: There are growing worries that the higher intensity radiation from 5G could harm those living close to cell towers. According to theories, the harm done to human DNA by this rise in radiofrequency radiation will result in cancer, premature ageing, and disturbance of cell metabolism.

If the weight of displaced liquid and the weight of an object are the same, the object will:
Answer:
Float
Explanation:
If the weight of liquid displaced and the weight of an object are the same, the object will float in the liquid.
From Archimedes principle, when an object is immersed in fluid, a force called upthrust supports it and it equal to the weight of the liquid displaced.
When in a liquid, the weight of the liquid displaced is the same as that of the of the object, it will float and not sink.

A. There were 3,140 kJ of energy in the snack.
B. There were 1,570 kJ of energy in the snack.
C. During her run, she used 755 Calories of energy.
D. During her run, she used 189 Calories of energy.
E. The runner used fewer Calories while running than she consumed during her snack.
F. The runner used more Calories while running than she consumed during her snack.
Answer:
B. There were 1,570 kJ of energy in the snack.
C. During her run, she used 755 Calories of energy.
F. The runner used more Calories while running than she consumed during her snack.
Explanation:
According to this question, a runner eats a snack with 375 Calories of nutritional energy. After her snack, she burns 3,160 kJ while running.
Since 1 Calorie = 4.184 kJ, it means that the runner consumed 375 × 4.184 = 1570 kJ of energy. In other words, THERE WERE 1,570 kJ OF ENERGY IN THE SNACK.
Also, the runner burns 3,160 kJ while running meaning that she equivalently burnt 3160/4.184 = 755.258 calories. Approximately, 755 calories of energy were burnt by the runner while running.
In a nutshell, the runner consumed 375 calories of energy in her snack but used up 755 calories while running. This means that the runner used more Calories while running than she consumed during her snack.

This reaction releases energy as heat. Explain whether the reaction is exothermic or endothermic and whether it obeys the law of conservation of energy
Answer:
Exothermic, it obeys the law of conservation of energy
Explanation:
The reaction is an exothermic change. In this kind of change, heat is liberated to the surrounding. So the surrounding becomes hotter at the end of the heat change.
In chemical reactions that involves the loss of energy as heat, they obey the law of conservation of energy.
The law of conservation of energy states that energy is neither created nor destroyed but transformed from one form to another. In such reactions as this, chemical energy is transformed into heat energy.

what is Bohr's atomic model?
Answer:
The Bohr model and all of its successors describe the properties of atomic electrons in terms of a set of allowed (possible) values. Atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states. Direct experimental evidence for the existence of such discrete states was obtained (1914) by the German-born physicists James Franck and Gustav Hertz.

N2 + 3H2 Right arrow. 2NH3 What is the percent yield of NH3 if the reaction of 26.3 g of H2 produces 79.0 g of NH3? Use Percent yield equals StartFraction actual yield over theoretical yield EndFraction times 100..
Answer:
53.4%
Explanation:
N₂ + 3H₂ → 2NH₃
Given that:
26.3 g of H₂ react with N₂ to produce 79.0 g of NH₃
Then:
The number of moles of H₂ = 26.3g of H₂ * (1 mol of H₂/ 2.02g of H₂)
= 13.05 mol of H₂
The number of moles of NH₃ = 13.05 mol of H₂ * ( 2mol of NH₃/ 3 mol of H₂)
= 8.697 mol of NH₃
The mass of NH₃ = 8.697 mol of NH₃ *( 17.04g of NH₃/ 1 mol of NH₃) = 148.1 g of NH₃
The percent yield = actual yield/ theoretical yield * 100%
The percent yield = ( 79.0 g/ 148.1 g )* 100%
The percent yield ≅ 53.4 %

54. Copper(I) sulfide is formed when copper and sulfur are
heated together. In this reaction, 127 g of copper reacts
with 41 g of sulfur. After the reaction is complete, 9 g of
sulfur remains unreacted. What is the mass of copper
sulfide formed?
SEL
Ma
Answer:
159g
Explanation:
Copper (I) sulfide is formed by the chemical reaction between copper and sulfur. Copper is a limiting reagent that results in the formation of 190.26 grams of copper(I) sulfide.
What is a limiting reagent?A limiting reagent is defined as the reactant that gets completely utilized in the reaction and affects the amount of the product formation. On the contrary, the excess reagent is present in more amounts.
Given,
Mass of copper = 127 gm
Mass of sulfur = 41 gm
Moles of copper:
n = mass ÷ molar mass
n = 127 ÷ 63.546
n = 1.99
Moles of sulfur:
n = 41 ÷ 32.065
n = 1.27
The reaction is shown as:
Cu + S → CuS
Here, 9 g of sulfur remains unreacted and hence is an excess reagent, and copper being consumed is a limiting reagent.
Here, 1 mole of copper reacts to form 1 mole of copper sulfide hence, 1.99 moles of Cu produces, 1.99 moles of copper sulfide.
Mass of CuS is calculated as:
Mass = moles × molar mass
Mass = 1.99 mol × 95.611 g/mol
= 190.26 grams
Therefore, 127 gm of copper and 41 gm of sulfur produces 190.26 grams of copper sulfide.

How could a synthetic material such as Acegram affect society?
Explanation:
Synthetic fiber or synthetic fibre (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). There are two types of polymerization: linear polymerization and cross-linked polymerization.
Synthetic material are madeup of monomers and long chain of monomers are known as polymers. The process is known as polymerization and the synthetic material are turned as microplastic which takes a long period of time to decompose. By this way the synthetic materials are very harmful for the society.
