Answer:
Mass – The single most important property that determines other properties of the star. Luminosity – The total amount of energy (light) that a star emits into space. Temperature – surface temperature, closely related to the luminosity and color of the star
Explanation:
It contains no large maria
An electric motor has an effective resistance of 29. 4 ω and an inductive reactance of 42. 6 ω. When working under load. the rms voltage across the alternating source is 442 v. The rms current will be 8.54 A
AC stands for “Alternating Current,” meaning voltage or current that changes polarity or direction, respectively, over time. AC electromechanical generators, known as alternators, are of simpler construction than DC electromechanical generators.
RMS or root mean square current/voltage of the alternating current/voltage represents the D.C current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, the RMS value equals peak value divided by the square root of 2.
I (RMS) = RMS voltage / 
= 442 / 
= 442 / 
= 442 / 
= 8.54 A

What does "which" mean ? Does it mean to pick the right one out of a list that you're hiding from us ?
There's no way we can begin to make a choice if we don't know WHAT the samples are samples OF.
I CAN give you some info, however, that will probably help you make the right choice from the hidden list that you have.
If water is on the list, then that's the answer, EXCEPT if liquid ammonia is on the list. Liquid ammonia is the only known substance on Earth that beats water as the answer to this question.
If neither liquid ammonia NOR water is on your secret list of samples, then you're on your own, Bunky.
