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:
SW
Explanation:
When a hurricane intensifies and the wind speed increases, an eye begins to form in the center of the storm. This normally occurs once the winds reach about 80 mph. Almost always the eye is circular when viewed from above, and measures about 20 to 40 miles in diameter. It looks cylindrical in a cross section of the storm, and extends through the center of the storm like a chimney. The air over the storm sinks through the center of the eye.
Hurricanes are formed from centers of low atmospheric pressures in warm waters around which strong air currents begin to circulate.
When ocean water heats up, the air rises and swirls to fill the low pressure that this creates.
This causes the air to be sucked in and up, which reinforces the low pressure in the center.
Thus, when the wind speed increases to 128 km / h, a kind of "vacuum" is created that meteorologists call "eye", since it has an almost circular shape.
