Answer:
a. Ssystem > 40 J/K
Explanation:
Given that
The entropy of first block = 10 J/K
The entropy of second block = 30 J/K
When two bodies come into contact with each other, the entropy of the combined system will increase and the entropy sum remains unchanged: According to the Second law of thermodynamics.The entropy of the system will be greater than 40 J/K.
Therefore the answer is a.
Ssystem > 40 J/K
The amplitude determines the volume of the sound. This isn't affected by the motion of the sound source.

Answer:
<em><u>energy</u></em>
Explanation:
The heating and cooling of molecule will make <em><u>energy</u></em> change their state of matter.
Answer:
B). increasing
Explanation
its increasing but at a constant rate, its growing consistently
Assuming that the time needed to cross the ammeter is 1 hour or 3600s, then using coloumb's law,
I x t = F x m / (eq. wt)
Using the given values and formula:
3 x 3600 = 96500 x m / (27/3)
Solving for m,
m = 1.007 g of Al3+
