How are computers used in producing weather forecasts? check all that apply. - they compile data from multiple instruments. - they collect air temperature and air pressure data. - they eliminate the need for human meteorologists. - they transmit data on developing weather systems from space. - they use mathematical equations to show what will happen to the atmosphere if conditions change.

-They compile data from multiple instruments.  

- They use mathematical equations to show what will happen to the atmosphere if conditions change.

The weather forecast agencies or institutions use supercomputers which can retain the data obtained from the satellites, radar, weather balloons, anemometer (wind speed measuring device) and from other instruments to give an appropriate information about the present or future weather conditions.

The computers can be used to solve the make the appropriate mathematical equation related to the atmospheric changes by applying various software tools which includes log function and statistics.

Explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
