Answer:
a = 0.827468
Explanation:
given,
half life of radium-224 = 3.66 days
now,
t is the time
A₀ is the amount at t = 0
at t = 0 , A(0) = 1
A(3.66) = 1/2
at t = 3.66
taking log both side
3.66 log (a) = log (0.5)
log a = -0.0822
now,
a = 0.827468
The orientation with the largest magnetic torque on the dipole is Orientation B (See attached image).
<h3>What is Magnetic Torque?</h3>The torque on the dipole is defined as:
τ = µ×B,
where B is the external magnetic field.
The magnitude of this torque is µB sinθ, where θ is the angle between B and µ
Magnetic Torque is highest when;
→ →
µ ⊥ β
That is when θ = 90°. Hence B is the correct answer. Please see attached image.
