There are three main reasons why people are concerned that cell phones (also known as “mobile” or “wireless” telephones) might have the potential to cause certain types of cancer or other health problems:
Cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation, from their antennas. Tissues nearest to the antenna can absorb this energy.
The number of cell phone users has increased rapidly. As of December 2014, there were more than 327.5 million cell phone subscribers in the United States, according to the Cellular Telecommunications and Internet Association. This is a nearly threefold increase from the 110 million users in 2000. Globally, the number of subscriptions is estimated by the International Telecommunications Union to be 5 billion.
Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. However, improvements in cell phone technology have resulted in devices that have lower power outputs than earlier models.
Answer:
Calculate the mass of 2.75 moles of ammonia.
Explanation:
The right-lateral transform fault occurs from the convergence of the Juan de Fuca and North American plates.
<h3>What is a
transform fault?</h3>
These fault occurs along which the relative motion between the two plates is parallel to the strike of the fault.
Therefore, the right-lateral transform fault occurs from the convergence of the Juan de Fuca and North American plates.

Answer:
Kuiper Belt
Explanation:
Like you correctly said, the short-period comets are thought to originate in the Kuiper Belt, which is an area outside Neptune's orbit, which is located from thirty to fifty light-year.
One of the primary uses for a 500-mb map is in determining the speed and direction of motion for midlatitudes cyclones.
<h3>What is
500-mb map?</h3>
500-mb map is a type of mapping system that has a constant pressure on the chart .
In this case, 500-mb map is in determining the speed and direction of motion for midlatitudes cyclones.
