I need help with the following questions!

My assignment is due 10:00 AM Tomorrow and I am stuck!

PLZ help me! All help will be appreciated greatly!

3. A wire 8.0 cm long moves with a velocity of 2.4 m/s through a magnetic field directed into the page, as shown on the diagram below.

A rectangular copper loop is placed in a magnetic field of strength 0.55 T, as shown below. 5 cm 18 cm - 24 cm - - - 26 cm a) Calculate the magnetic flux for the loop. a) 2 marks b) The magnetic field is suddenly shut off. In which direction will current be temporarily induced in the loop when this happens? Check one below. I mark O clockwise O counterclockwise c) If it takes 0.13 s for the magnetic field to be shut off, what is the average EMF induced in the loop?5. A circular coil of wire, of 20 turns and radius 0.15 m, is rotating uniformly at 10.0 Hz about an axis in the plane of the coil and perpendicular to a uniform field of 0.30 T. a) Determine the magnetic flux when the plane of the coil is at right angles to the field lines. a) 2 marks b) What is the average EMF induced in the coil due to its rotation in the field
