<h3>yes, there are human health risks caused by exposure to x rays</h3>
  • describe the main risk (s) ::: - may cause damage to cells in the body

                                                      - large doses may lead cells to be cancerous        

                                                      - causes mutations in the DNA

  • describe common sources of exposure ( or overexposure ) :::

           - natural background radiation   e.g. - cosmic rays

           - medical radiation   e.g. - CT scans & medical x - rays

           - man - made radiation   e.g. - airport security scanners

  • describe a technology, device, or behavior that can be used for protection, or to decrease exposure :::

          - x - ray beam filters

          - digital x - ray detectors

          - technologies reduce radiation doses in radiography &  

            mammography

<em>hope that helps !!</em>

Elan Coil [88]

Answer:

Scientists plan to release a space probe that will enter the atmosphere of a gaseous planet. The temperature of the gaseous planet increases linearly with the height of the atmosphere as measured from the top of a visible boundary layer, defined as 0 kilometers in altitude. The instruments on board can withstand a temperature of 601 K. At what altitude will the probe's instruments fail? A. 50 kilometers B. 80 kilometers C. 83 kilometers D. 100 kilometers E. 111 kilometers

Explanation:

A. 50 kilometers

A mass m = 550 g is hung from a spring with spring constant k = 2.8 N/m and set into oscillation at time t = 0. A second, identi
riadik2000 [5.3K]

Answer:

The second system must be set in motion t=0.70s seconds later

Explanation:

The oscillation time, T, for a mass, m, attached to spring with Hooke's constant, k, is:

T=2\pi\sqrt(\frac{m}{k} )

One oscillation takes T secondes, and that is equivalent to a 2π phase. Then, a difference phase of π/2=2π/4, is equivalent to a time t=T/4.

If the phase difference π/2 of the second system relative to the first oscillator. The second system must be set in motion t=\frac{\pi}{2}\sqrt(\frac{m}{k})=\frac{\pi}{2}\sqrt(\frac{0.55}{2.8}= 0.70s) seconds later
