Astudent claims that water's polarity is the reason it has a high specific heat. what method could the student use to test his claim? perform research to see if other polar molecules have high specific heat. measure how much energy it takes to increase the temperature of water by one degree. mix water with an acid and test the new specific heat. determine how dissolving salt in water affects the specific heat.

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
