The sport of curling involves two teams sliding smooth, heavy stones along ice, as shown below. The teams try to get the stones close to a target. During a curling match, the stones often hit each other, causing a transfer of energy. To improve their throwing accuracy, athletes are practicing on a frictionless surface. The data table below summarizes the motion of one particular stone, stone 1, during the practice session.

At t = 0 s, stone 1 is released from the athlete's hand. At t = 8 s, the stone collides with a second stone, stone 2, which was initially at rest. During the collision of stones 1 and 2, a minimal amount of energy is lost to the surroundings.

Assuming that stone 2 does not hit any other stones, which of the given data tables could summarize the motion of stone 2 over this same time period?

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
