Answer:
(i)The current flow in black wire = 9.67 A (ii) The current low in the red wire is 9.68 A (iii) The current flow in neutral wire is 15.36 A (iv) when 240 volt were disconnected current in black wire is 7.68 A (v) when 240 volt were disconnected current in red wire is 7.68 A (vi) 15.36 A (vii) 6.34 (viii) 9.68 A (ix) 12.02 A
Explanation:
Solution
The current drawn by one amp is
I =P/V
I =200/120
I= 1.67 A
(i) The current flow in the black wire is
IBK = 4 * 1.67 A + 1A + 2A
IBK = 9.67 A
(ii) Current flow in the red wire is
IRD = 3 * 1.67 A + 1.67 A + 1A + 2A
= 8.68A + 1 A = 9.68 A

Answer:
(a). The rotational inertia is
(b). The magnitude of the magnetic torque is
Explanation:
Given that,
Mass of neutron
Density of neutron
(a). We need to calculate the rotational inertia
Using formula of rotational inertia for sphere
...(I)
We know that,
Put the value of volume
Put the value of R in equation (I)
Put the value into the formula
The rotational inertia is .
(b). We need to calculate the magnitude of the magnetic torque
Using formula of torque
Put the value into the formula
The magnitude of the magnetic torque is
Hence, (a). The rotational inertia is
(b). The magnitude of the magnetic torque is
