For this
specific problem, the maximum value for d is 52m. I am hoping
that this answer has satisfied your query about and it will be able to help
you, and if you’d like, feel free to ask another question.
Answer:
a).
b).
Explanation:
a).
Using the law of thermodynamic and using to isovolumetric
ΔU=Qh
So to determine the internal energy knowing the work it do
b).
Efficiency is the work done in relation of the work apply in this case to produce heat so:
Solve to Qc
![Q_{c}=Q_{h}*[1-E]](https://tex.z-dn.net/?f=Q_%7Bc%7D%3DQ_%7Bh%7D%2A%5B1-E%5D)
Answer:
R = 0.93 ohms
Explanation:
Let's start by calculating the resistance of the coil,
V = I ( R + r )
Make R the subject of the above equation.
Hence,
V = IR + Ir
V - Ir = IR
( V - Ir )/I = R
Given that V = 10V
r = 0.07ohms
I = 10A ( this is an assumption )
( 10 - 10×0.07 ) ÷ 10
R = 0.93 ohms
Note: r is the internal resistance, R is the resistance, I is the current and the emf is represented as V. Since current was supposed to be included in the question but it was not, hence it was assumed to be 10A . Meaning whatsoever value is given for current will be substituted into the equation. Thanks
