What does a triple-beam balance requires the user to do a. add the numbers from the three sliders to determine that mass of an objectb. multiply the numbers from tje tree sliders to determine the mass of an objectc. add the numbers from the three sliders to determine the volume of an objectd. multiply the numbers from tje three sliders to determine the volume of an object

Option (A)

Explanation: A triple beam balance is generally used in order to determine the mass of any object very accurately, in terms of gram. This is calculated by adding up the values of all three sliding blocks (the largest one, the medium one and the smallest) that we get from the measurement. There can be an error of about 0.05 grams.

Thus, Option (A) is the correct answer.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
