a
Explanation:hope this helps
For the answer to the question above,
the distance from i to j is 5 parts
(2 parts from i to k and 3 parts from k to j)
The y distance from i to j is
10 - 2 = 8
Each part is 8/5 = 1.6
Therefore the distance between the 2 parts from i to k is 3.2
From the y coordinate of I which is 2 plus the 3.2 to point k
2 + 3.2 = 5.2
Answer y =5.2
Now just convert that to fraction and that will be the answer
Answer:
ΔS = 3.09 J/K
Explanation:
Entropy is defined as the magnitude of disorder in a system. Mathematically, entropy change is given as, the heat absorbed or released by a system divided by the change in absolute temperature. So, the formula for entropy change is as follows:
ΔS = ΔQ/ΔT
where,
ΔS = Change in Entropy of Metal Wire = ?
ΔQ = Heat Conducted through Wire = 1216 J
ΔT = Difference in Temperature = 686 K - 292 K = 394 K
Therefore,
ΔS = 1216 J/394 K
<u>ΔS = 3.09 J/K</u>
Answer:

Explanation:
The charge of 1 elementary charge is given by
which corresponds to the charge of the proton.
To find the charge of 100 elementary charges (100 e), we need to solve the following proportion:
Solving for x we find
