A group of students performed an experiment to prove the law of conservation of energy. In the experiment, a flask containing water at room temperature was shaken vigorously for a few minutes. The table shows a partial record of the temperature of the water before and after shaking.

Experimental Record
Temperature
Before Shaking 20 °C
After Shaking Unknown

What best predicts the unknown temperature?
Group of answer choices

Less than 20 °C because the total energy of the system after shaking is lower

Greater than 20 °C because the total energy of the system after shaking is higher

Less than 20 °C, because the mechanical energy from shaking transforms to thermal energy

Greater than 20 °C, because the mechanical energy from shaking transforms to thermal energy

Which element is used in photosynthesis found in atmosphere and fixed by bacteria?

When analyzing tree rings, what do scientists assume a thin ring indicates?

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
