Answer:
Weight = 45880 kN
Explanation:
Gas pipeline material is steel.
Density of steel = 7850 kg/m³
Mass = Volume x Density
Volume = Area x Length
Outer diameter = 610 mm
Internal diameter = 610 - 2 x 12.7 = 584.6 mm
Length = 25 km = 25000 m
Volume = 25000 x 0.0238 = 595.78 m³
Mass = 595.78 x 7850 = 4676875.12 kg
Weight = Mass x Acceleration due to gravity = 4676875.12 x 9.81 = 45880 kN
Weight = 45880 kN
Answer:
Explanation:
As the circuit is parallel, then there is no effect of other branches as the potential difference across each arm is same.

Answer:
The distance the planet Neptune travels in a single orbit around the Sun is <em>60.2π </em><em>AU.</em>
Explanation:
As it is given that the Neptune's orbit is circular, the formula that we have to use is the circumference of a circle in order to find the distance it travels in a single orbit around the Sun. In other words, you can say that the circumference of the circle is <em>equivalent</em> to the distance it travels around the Sun in a single orbit.
<em>The circumference of the circle = Distance Travelled (in a single orbit) = 2*π*R ---- (A)</em>
Where,
<em>R = Orbital radius (in this case) = 30.1 AU</em>
<em />
Plug the value of R in the equation (A):
<em>(A) => The circumference of the circle = 2*π*(30.1)</em>
<em> The circumference of the circle = </em><em>60.2π</em>
Therefore, the distance the planet Neptune travels in a single orbit around the Sun is <em>60.2π </em><em>AU.</em>
