Geologists working for the Environmental Protection Agency monitor surface waters at sites across the country to determine the effects of acid rain on aquatic ecosystems. What type of information would the geologists most likely track? A; human activity B; pH Levels C;Gas Emissions D; Climate Patterns

pH Levels

Explanation:

Acid rain refers to  precipitation that contains an elevated level of hydrogen ions. It has harmful effects on plants, aquatic animals, buildings and sculpture.

Acid rain alters the pH of surface waters leading to a sudden increase in acidity. This negatively affects organisms with low tolerance for the sudden upward surge in H^+ concentration.

If the geologists are to study surface waters in order to determine the effects of acid rain, then they have to study the pH of the water.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
