Answer:
- Gap between the plates
- No, practically not achievable
Solution:
As per the question:
Capacitance, C = 1 F
Area of the plate of the capacitor, A =
Now,
To calculate the distance, D between the plates of a parallel plate capacitor:
Thus
where
= permittivity of free space
Now,
This distance much smaller and is practically not possible
Answer:
ΔL = 3.704 10⁻⁴ mm
Explanation:
The body when heated increases the distance between its atoms, which results in a linear expansion of the bodies, which is described in the first approximation by the expression
ΔL = α L Δt
Where alf is the linear expansion coefficient, L the initial length, Dt the temperature variation and DL the length variation
ΔL = 5.50 10⁻⁷ 3.49 (213 - 20)
ΔL = 3.704 10⁻⁴ mm
