Charles's Law<span>, or the </span>law<span> of volumes, was found in 1787 by Jacques </span>Charles<span>. It states that, for a given mass of an </span>ideal gas<span> at </span>constant<span> pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system. The constant parameters would be the number of moles and pressure.</span>

Answer:
9.88 milivolt
Explanation:
Given: diameter d = 5.2 cm
magnetic field B_1 = 1.35 T, final magnetic field B_2 =0 T
t = 0.29 sec.
we know emf = - dΦ/dt
and flux Φ = BA
A= area
therefore emf ε = -A(B_2-B_1)/Δt
