Asingle conducting loop of wire has an area of 7.26e-2 m2 and a resistance of 117 ω. perpendicular to the plane of the loop is a magnetic field of strength 0.289 t. at what rate (in t/s) must this field change if the induced current in the loop is to be 0.367 a?

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
