Explanation:
( in the south direction)
(in the west direction)
so direction of v_1 and v_2 are north and west respectively.
we used the formula for relative velocity
is the velocity of B with respect to A.
The magnitude of the magnetic moment due to the electron's motion is .

What is magnetic moment?</h3>
The magnetic pull and direction of a magnet or other object that produces a magnetic field are referred to as the magnetic moment in electromagnetism. Things that have magnetic moments include electromagnets, permanent magnets, various compounds, elementary particles like electrons, and a number of celestial objects (such as many planets, some moons, stars, etc).
The term "magnetic moment" really refers to the magnetic dipole moment of a system, which is the portion of the magnetic moment that can be represented by an equivalent magnetic dipole or a pair of magnetic north and south poles that are only very slightly apart. The magnetic dipole component is adequate for sufficiently small magnets or over sufficiently large distances.

Answer:
Total voltage of the battery is 12 volts.
Explanation:
It is given that, we have three identical resistors of resistance 3 ohms are connected in series in a circuit. It is required to find the total voltage of the battery if the current in the circuit is 2 A.
Let is the equivalent resistance in series combination. The equivalent resistance is given by :
Let V is the total voltage of the battery. Ohm's law is given by :
So, the total voltage of the battery is 12 volts.
Answer:
Explanation:
given,
rotational inertia, I = 474.0 kg·m²
decrease in angular velocity
ω₁ = 26.2 rad/s ω₂ = 0 rad/s
time = 204 s
torque = ?
α = 0.128 rad/s²
frictional torque acting by the flywheel is equal to 60.88 N.m
Question isn’t clear
If it’s asking the no of electrons then -
No of electrons =no of protons in an atom of a element ....therefore there are 11 electrons
