Calculate how much heat energy you will need for this situation. you have a 1 kg water at 0°c. you warmed it up to 100 °c the water turns into steam with temperature 100°c. the specific heat of water is about 4200 joules per kilogram per degree c. the latent heat of vaporization is 2257000 joules per kilogram.

Which example has gravitational potential energy? a.a horse slowing down from a run b.an apple about to fall from a tree branch c.a bicycle being pedaled down a horizontal path d.beaker sitting on the floor

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.
