P3 Please solve this problem very clearly and briefly with step by step explanation. 13. (II) A toroid has a rectangular cross section as shown inFig. 30-26. Show that the self-inductance isLMo N²hIn ¹22π "₁where N is the total number of turns and r₁, 2, and h arethe dimensions shown in Fig. 30-26. [Hint: Use Ampère'slaw to get B as a function of r inside the toroid, andintegrate.]FIGURE 30-26Problems 13 and 19.A toroid of rectangularcross section, withN turns carrying acurrent I.

2. A bead on a wire can slide with negligible friction on a hoop with radius R rotating at a constant rate with a period T. а. Find the angle 0 at which the bead would not slide on the hoop. Express this in terms of the values given above and any constants (e.g. g). Note: A FBD and proper setup of NII equations are required here. Do your algebra. b. If the period increases, will the bead slide upward, slide downward, or do neither? Explain why, using your result from part a. Can 0 be greater than or equal to 90°? Why or why not? Use FBDS and your result С. from part a as evidence. d. Are there any other angles at which the ball will not slide on the hoop? Explain why. Note: Think very carefully about your forces here. Use FBDS.

Mass mrests on a smooth horizontal surface, mp hangs vertically. Part A If mA = 12.0 kg and mp=3.0 kg in the figure, MA MB determine the magnitude of the acceleration of each block.
A frog jumps at an angle 30° above the horizontal. The origin of the coordinate system is at the point where the frog leaves the ground. Complete the attached table by drawing check marks in the cells that correctly connect the quantities in the first column that describe the motion of the frog and the descriptions of what is happening to these quantities while the frog is moving. For each quantity, explain why your choice is correct. Consider the frog as a point-like object and assume that the resistive force exerted by the air is negligible.
