Each of the loops in the diagram above are identical. Each has a length of 0.2 m, a width of 0.06 m, and a resistance of 0.02 N. Each is moving with a speed of 0.30 m/s. Loops B, C, and D each have 0.09 m of their lengths not in the magnetic field at the time shown in the diagram. The magnetic field, B = 0.40 T, is directed into the page. What is the direction of the induced current for each loop at the instant shown in the diagram?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.
