What does the term "heat capacity" refer to? Question 2 options: The amount of heat energy needed to raise the temperature of a unit mass of a material one degree A ratio of the amount of heat a material will absorb to the amount of heat it immediately releases The amount of heat that must be applied to a solid to convert it to a liquid The amount of heat that a liquid can absorb until the particles speed up enough to become a gas

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.

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2

Relative to the ground below, how many joules of potential energy does a 1000-kg boulder have at the top of a 5-m ledge?
