You’ve just been involved in a traffic accident that leaves you stranded on the side of the road. <u>Microwaves from the EM spectrum would be of the most use.</u>
<u></u>
Explanation:
- Microwaves are a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter, with frequencies between 300 MHz and 300 GHz.
- Microwaves have a range of applications, including communications, radar and, perhaps best known by most people, cooking
- Microwave is a line-of-sight wireless communication technology that uses high frequency beams of radio waves to provide high speed wireless connections that can send and receive voice, video, and data information.
- Microwaves and radio waves are used to communicate with satellites.
- Microwaves pass straight through the atmosphere and are suitable for communicating with distant geostationary satellites, while radio waves are suitable for communicating with satellites in low orbit.
- Microwaves are widely used in modern technology, <u>for example</u> : in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, etc
Answer: Core muscles protect the spine and keeps it stabilized. Also they can help control movements such as walking and standing. The core helps transfer energy and help us move in different directions. It's important to have a strong set of core muscles.
