Please if you don't know how to answer my questions, pleasedon't just submit wrong answers orCHATGPTanswers which I will report you.

When you do it, take your time, but I need a correct explanation step by step and especially for the direction explain it simply so I can understand it, for each one and complete the whole questions to answer them correctly.

D=20 B= 40 2. a. A moveable (massless and frictionless) bar with a length of L - 0.50 m is being moved at a constant velocity of 10 - m/s from left to right along two conducting rails by an external force, F, as shown in the Figure. If the system is immersed in a uniform magnetic field (out of the paper) with magnitude B Tesla, What is the induced current and its 100 direction of the loop if the resistance is 4.0 $2? (20 Points) O O b. Unpolarized light with intensity Io is incident on a series of polarizing sheets. The first sheet has its transmission axis oriented at 90 w.r.t +X. A second polarizer has its transmission axis oriented at 450 w.r.t +X. A third polarizer has its transmission axis oriented Do w.r.t +X. Determine the fraction of light intensity exiting the third sheet and show all work? (10 Points) c. If a coil is expanding in a magnetic field pointing out from the page, in what direction is the induced current? (10 Points)
