The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time.
Take that as you will
<span>The distance covered by the tectonic plate, in meters, is
</span>

<span>
The time taken for the tectonic plate to cover this distance is equal to
</span>

<span>
Therefore, the average velocity of the tectonic plate is the ratio between the distance covered and the time taken:
</span>

<span>
</span>
This is very good conceptual question and can clear your doubts regarding work-energy theorem.
Whenever force is perpendicular to the direction of the motion, work done by that force is zero.
According to work-energy theorem,
Work done by all the force = change in kinetic energy.
here, work done = 0.
Therefore,
0=change in kinetic energy
This means kinetic energy remains constant.
Hope this helps
Given : Initial velocity = -1.3 m/s
Final Velocity = -6.5 m/s.
Time = 25 minutes.
To find : Average acceleration.
Solution: We are given units in meter/second (m/s).
So, we need to convert time 25 minutes in seconds.
1 minute = 60 seconds.
25 minutes = 60*25 = 1500 seconds.
Formula for average acceleration is given by,

We are not given intial time, so we can take initial time =0.
Plugging values in the above formula.

= 
= -0.003467
or
.
Answer:
X and Z
Explanation:
Conduction occurs through direct physical contact. Heat transferred from the pot to the handle, and from the handle to the hand, are both examples of conduction.
