How long does radioactive isotope stay in your body? The half-lives of radioisotopes used in medicine range from a few minutes to a few days. For example, rubidium-82, which is used for myocardial perfusion imaging has a half- life of 1.26 minutes, while iodine-131, used in thyroid treatment and diagnosis, has a half- life of […]

In what way are the chemical equations useful to us?
In what way are the chemical equations useful to us? ↵Chemical equation gives us the complete information about the reaction taking place. It tells the number of atoms of each element participating in the reaction. It tells the neccerssary requirements such as temprature, catalyst, etc. It also tells us the state of the elements in […]

What are three things that affect longshore currents?
What are three things that affect longshore currents? When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. Conversely, a wider breaking angle, gentler beach slope, and lower wave height slows a longshore current’s velocity. What causes long […]
How accurate is a spectrophotometer?
How accurate is a spectrophotometer? The minimum is not sharp and good results can be expected in a transmittance range from 0.2 to 0.6 or an absorbance range from 0.7 to 0.2. An inspection of the graph below indicates that transmittance values of 0.1 and 0.8 are the outside limits between which one can expect […]
