The circuit was installed in UF cable which requires a minimum burial depth of 6 inches for this circuit.
<h3>
UF cable</h3>
UF cable is used as an underground feeder cable to distribute power from an existing building to outdoor equipment. UF cable can also be used as direct burial cable.
For the 24-volt branch circuit installed, the minimum burial depth will be 6 inches.
Thus, the circuit was installed in UF cable which requires a minimum burial depth of 6 inches for this circuit.

Explanation:
Electrical resistance can be defined as the opposition to the flow of current in an electric circuit or wire. The resistance converts electrical energy into thermal energy, this serves as friction in mechanical systems. And this electrical energy converted to thermal is dissipated.
By ohm's law we have
Resistance R = Voltage V/ Current I
There's really no "why", because it's not difficult at all.
Simply multiply the number of miles by 1,760, and bada boom,
there you have the same distance described in yards.
Answer:
v = 200.005 m / s
Explanation:
For this exercise we can use the concept of energy conservation,
Starting point. When the asteroid at h = 1000 km = 1 10⁶ m
Em₀ = K + U = ½ m v₀² - G m M / (R + h)
Final point. When the asteroid is on the surface of the moon
Emf = K + U = ½ m v² - G m M / R
As there is no friction the energy is conserved
Em₀ = Emf
½ m v₀² - G m M / (R + h) = ½ m v² - G m M / R
½ m (v₀² –v²) = G m M (-1 / R + 1 / R + h)
½ (v₀² - v²) = G M (-h / R (R + h))
v² = v₀² + 2 G M h / R (R + h))
Let's calculate
v² = 200² + 2 6.67 10⁻¹¹ 7.36 10²² / 1.74 (1.74 + 1 ))10¹²
v2 = 40000 + 2,059
v = 200.005 m / s
