The specific heat of copper is 0.385 j/g•°c. which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of aluminum from 7°c to 29°c? q = 0.75 g x 0.897 j/g•°c x 29°c q = 0.75 g x 0.385 j/g•°c x 22°c q = 0.75 g x 0.385 j/g•°c x 29°c q = 0.75 g x 0.897 j/g•°c x 22°c

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
