I have already done the solutions but id like to check they are correct, i just need answers.

Problem 1 A capactor initially charged to a voltage AV is discharged through a resistor beginning at time / # 0. How does the current through the resistor change as a function of a time? Select One of the Following: (a) The current is constant. (b) The current continuously decreases with time. (c) The current continuously increases with time. (d) The current instantly becomes zero. Problem 2 What is the cross product, x B, of the vectors I - 27/ and B = 52? Select One of the Following: ( a) y ( b ) 2 (c) 10r (d) + 101 (e) +107 (f ) -10y (8) 103 (h) + 103 Problem 3 The figure to the right shows two wires. Both wires carry a current I out of the page What is the direction of the magnetic field at the point I'? Select One of the Following: (a) The magnetic field points to the bottom of the page (b) The magnetic field points to the top of the page (c) The magnetic field points to the left of the page (d) The magnetic field points to the right of the page (e) The magnetic field points into the page. (f) The magnetic field points out of the page. (g) The magnetic field is zero
