Arectangular loop of wire with side lengths a and b lies in the first quadrant of the ry plane with one corner at the origin. the side along the r-axis has length a. a nonunifornm magnetic field b(y, t) =-ky3t2ż + k~5t2x, where k is a positive constant. (a) find the magnetic flux through the loop as a function of time (b) find the emf induced in the rectangular loop. (c) will the current resulting from the induced emf flow clockwise or anti-clockwise when viewed from a point in space with z > 0?

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?

3. a lunar exploration vehicle was created by a research team. it weighs 3,000 kg on the earth. it needs an acceleration of 10 m/s2 on the moon. in order to have the same acceleration, what will be the net force acting on the vehicle on the earth?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
