Ludmilka [50]

Answer:

d. none of these

Explanation:

From the given information:

Let assume that Percival catches Sir Rodney's horse in time "t" after covering a certain distance "s"

Then, using the second equation of motion:

S = ut + \dfrac{1}{2}at^2

FOR Percival, we have:

S = (0\times t ) + \dfrac{1}{2} \times 0.6 \ m/s \times t^2  \\ \\  S = 0.3 \ m/s \times t^2  -- --  (1)

FOR Sir Rodney;

S = ut + \dfrac{1}{2}at^2

S = (3\times t ) + \dfrac{1}{2} \times 0 \times t^2  \\ \\  S =3t---  (2)

Equating both equations together; we have:

0.3t² = 3t

0.3t² - 3t = 0

0.3t(t - 10) = 0

If Percival's position at rest = 0

Then; t = 10 s.

What is entropy?
AysviL [449]

Answer: Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.
