Answer:
the pressure of gas is 100.0 the volume is 500.0
Explanation:
Because in SI, the expectation is that area and volume will be expressed in terms of a linear dimension( the metre) or its multiples.
Ans
1. d.x-Rays
2. d.modern medical x-rays use stronger radiation than earlier types.
3. b.Radio waves have high frequency
4.a.Gamma radiation
5.b.Infrared radiation
6.a.Radio waves
<u>Explanation:</u>
- A mammogram is an X-ray of the breast. Mammograms are commonly used to screen for breast cancer.
- Radio-tracking technology assists in determining exactly where an animal is located at any instant in time and frequently what that animal is performing! Utilizing the data collected from tracking devices, scientists can conclude the day-to-day activities of an animal, the size of an animal's place range, what other animals share an animal's range and the types of habitats an animal practices.
- Gamma-rays are the common energetic form of light and are generated by the most heated regions of the universe. Gamma rays are provided by such extreme events as supernova explosions or the elimination of atoms and by less exciting events, such as the breakdown of radioactive material in space.
When you have both of these ( The periodic table of elements and the formula of your compound) you are able to calculate the R.M.M ( Relative atomic mass) of that compound.
For example the formula of a NaCl ( Table salt ) has the elemnt Na and Cl.
We look at the atomic mass of both of these compounds
Na - 23
Cl - 35.5
R.M.M = 23 +35.5 = 58.5
Hope this helps :).
