A coil of wire with 60 turns lies on the plane of the page, and a uniform magnetic field points into the page with a strength of 1.10 T. The coil has an initial area of 0.890 m2 and is then elongated so that its area decreases to 0.270 m2 in 0.80 s. What is the magnitude of the average induced emf in the coil while its area is changing? 59.334 Incorrect: Your answer is incorrect. V

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.

You are the coordinator for a program that is going to take place at night in a rectangular amphitheater in the mountains. you will have no access to any electricity, but you must be able to illuminate the entire grounds. you know the intensity of the light from a lantern varies inversely as the square of the distance from the lantern. suppose the intensity is 90 when the distance is 5 m. a. write an equation to model the situation. b. solve for the constant of variation. c. write the equation to model the situation using the constant () of variation. d. you have been given lanterns with 40 light intensity. use your equation to solve for the distance from the lantern. e. you need to illuminate 225 km. how many meters do you need to light? f. how many lanterns will you need?

What is the quantity which is measured by the area occupied below the velocity- time graph?
