Answer:
C. When the temperature of the liquid is the same throughout
Explanation:
Yes yes multiply hurry up
Answer:
Explanation:
Let assume begins movement at zero point, that is, height is equal to zero. The block has an initial linear kinetic energy and no gravitational potential energy and end with no linear kinetic energy, some gravitational potential energy and work losses due to slide friction. In mathematical terms, this system can be model as follows:

Where
are linear kinetic energy, gravitational potential energy and work, respectively.
The answer is B (The second one). I'm not sure though.
