<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>
Answer:
Be sure to unplug the power source of all electrical equipment before working on it. Always pull from the plug, not the cord. Always wear proper non conductive clothing – insulated gloves, non conductive protective apparel and shoes with insulated soles. Avoid loose clothing or ties.
Answer:
Explanation:
= Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 m
m = Mass of person
The force on the person will balance the gravitational force
The acceleration that the Earth will feel is
Answer:
15 m/s to the right
Explanation:
Let's say right is positive and left is negative.
Momentum is conserved:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(6.0 kg) (25.0 m/s) + (15 kg) (0 m/s) = (6.0 kg) (-12.5 m/s) + (15 kg) v₂
v₂ = 15 m/s
Answer:
500x
Explanation:
A microscope had an eyepiece magnification of 10x
The objective lens magnification is 50x
Therefore the total magnification can be calculated as follows
= 10 × 50
= 500x
Hence the total Magnificattion is 500x
