A ferry transports tourists among three islands. It sails from the first island to the second island, 4.17 km away, in a direction 37.0° north of east. It then sails from the second island to the third island in a direction 74.0° west of north. Finally, it returns to the first island, sailing in a direction 28.0° east of south.
(a) Calculate the distance between the second and third islands.
(b) Calculate the distance between the first and third islands.
How do you get the distances btw the islands and their degrees?
A wire has a resistance of 60.0 ohms, and is bent into a squareloop with sides of length 15.0 cm. The loop is perpendicularto a magnetic field which is changing at a rate of7.000e-3 T/s. What is the current induced in the wire?
