Hello tutors, i need help with this practice problem.

Problem 2: A loop of wire with radius r =0.015 m is placed in a region of uniform magnetic field with magnitude B. As shown in the figure, the field direction is perpendicular to the plane of the loop. The magnitude of the magnetic field changes at a constant rate from B1 =0.65 T to B2 =4.5 T in time At =5.5 s. The resistance of the wire is R =7 0. Part (a) Enter an expression for the magnitude of the magnetic flux through the loop using the symbols in the palette below. Your expression must be valid at all times described in the problem statement. Expression : P = Select from the variables below to write your expression. Note that all variables may not be required. At: =0: Mo: 7: B, B1: B2: e, r, R Part (b) Enter an expression for the change in the magnitude of the magnetic flux through the loop using the symbols in the palette below. Expression Ad = Select from the variables below to write your expression. Note that all variables may not be required. At. =0: Mo: n, B, B1: B2: e, r. R Part (c) Calculate the numerical value, in tesla squared meters, of the change in the magnitude of the flux. Numeric : A numeric value is expected and not an expression. Ad = Part (d) Enter an expression for the magnitude of the induced emf in the loop using the symbols in the palette. Expression E= Select from the variables below to write your expression. Note that all variables may not be required. AD. At: EQ= Ho: n, B. B1: B2: r. R Part (e) Calculate, in volts, the numerical value of the magnitude of the emf. Numeric : A numeric value is expected and not an expression. E= Part (f) Enter an expression for the magnitude of the current induced in the loop using the symbols in the palette. Expression : Select from the variables below to write your expression. Note that all variables may not be required. Ad, At, E. Ho: n, B. B1: B2: r, R Part (g) Calculate the numerical value, in amperes, of the magnitude of the induced current. Numeric : A numeric value is expected and not an expression. I = Part (h) If you are looking down at the loop from above, so that the magnetic field is directed towards you, what is the direction of the induced current? MultipleChoice : 1) counterclockwise clockwise
