The common uses of radioactive elements in health care.

I-131, P-32, Sr-90, Co-60 & Technetium.

Explanation: Isotopes like I-131 are used to diagnose goiter in thyroid gland and isotopes like P-32 Sr-90 are used for treatment of skin cancer and Co-60 for cancer and technetium is used to monitor bone growth.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
