Answer:
<h2>Non-Ionizing Radiation From Wireless Technology
</h2>
Radiofrequency (RF) energy is a type of electromagnetic radiation. It is used to transmit signals carrying information in the form of radio waves. Radio waves are broadcast using a transmitter. When the radio waves reach a receiver, the signal is converted back into the information that was originally sent by the transmitter. When you talk on a cell phone, your cell phone acts as a transmitter and your voice is carried on radio waves to the person you are calling. Their phone acts as the receiver and converts the signal back into your voice. In addition to cell phones, other wireless devices such as radios, Wi-Fi routers, satellites, radars and pacemakers can send or receive RF energy waves.
Answer:
This result is a very good approximation, because R>>d
Explanation:
The capacitance for two parallel flat plates, with surface S, space between them d, is:
This calculation is based on the fact that the electric field is constant between the plates. This only happens if the area of the plates is much larger than the distance between them: S>>d, i.e. R>>d. If we assume these factors, the result has a very good approximation.

Answer:
57.4 m/s
Explanation:
Component of vectors parallel to the ground = v sin(titha)
= 100×sin35
= 57.4 m/s
