A conducting wire formed in the shape of a right triangle with base b = 28 cm and height h = 83 cm and having resistance R = 2.8 ?, rotates uniformly around the y-axis in the direction indicated by the arrow (clockwise as viewed from above (loooking down in the negative y-direction)). The triangle makes one complete rotaion in time t = T = 1.2 seconds. A constant magnetic field B = 1.1 T pointing in the positive z-direction (out of the screen) exists in the region where the wire is rotating.1)What is ?, the angular frequency of rotation?2)What is Imax, the magnitude of the maximum induced current in the loop?3)At time t = 0, the wire is positioned as shown. What is the magnitude of the magnetic flux ?1 at time t = t1 = 0.45 s?4)What is I1, the induced current in the loop at time t = 0.45 s? I1 is defined to be positive if it flows in the negative y-direction in the segment of length h.5)Which of the folowing statements about?o, the magnitude of the flux through the loop at time t = to = 0.3 s, and Io, the magnitude of the current through the loop at time t = to = 0.3 s, is true? ?max and Imax are defined to be the maximum values these quantites achieve during the complete rotation. a.?o = 0 and Io = 0b.?o = 0 and Io = Imaxc.?o = ?max and Io = 0d.?o = ?max and Io = Imax6)Suppose the frequency of rotation is now doubled. How do ?max, the maximum value of the flux through the loop, and Imax, the maximum value of the induced current in the loop change?a.?max and Imax both doubleb.?max doubles and Imax remains the samec.?max remains the same and Imax doublesd. Both ?max and Imax remain the same

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?
