Answer:
a. U = 1.68 μJ
b. i = 7.39 mA
Explanation:
a.
The energy total of the circuit can be find using
U = Q ² / 2 * C
Q = 3.56 μC
C = 3.77 μF
U = (3.56 μC ) ² / 2 * 3.77 μF
U = 1.6808 x 10 ⁻⁶ J
U = 1.68 μJ
b.
Now to determine the current in the circuit
U = ¹/₂ * L * i²
i² = 2 * U / L
i = √ 2 * U / L
i = √2 * 1.68 μJ / 61.5 mH
i = 7.39 mA
Answer:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

Answer:
The focal length for given convex lens = 0.0714 m
Explanation:
Given data
Radius () = 12.5 cm
Radius () = 16.7 cm
Since the radius of curvature is positive so these are the convex lens.
Now focal length is given by
⇒ = +
⇒ Put the values of and in the above formula we get,
⇒ = +
⇒ = 0.13988
⇒ f =
⇒ f = 7.14 cm
⇒ f = 0.0714 m
Thus the focal length for given convex lens = 0.0714 m
Answer:
Explanation:
Since the temperature difference between inner and outside temperature remains constant , condition of steady state has been achieved . So heat produced is equal to heat leaked
heat leaked = heat produced
heat produced = 54 kwh = 54 x 1000 x 60 x 60 J
time taken = 3 x 60 x 60 s
heat produced per second
= 54 x 1000 x 60 x 60 / 3 x 60 x 60
= 18000 J /s
heat leaked = 18000 J /s
