C D www.webassign.net/web/Student/Assignment-Responses/submit?dep-13000194 2. In the figure below, two streight conducting rals form a right angle. A conducting bar in contact with the rails starts at the vertex at m/s along them. A magnotie field with E 0.350 T is directed out of the page. time t O and moves with a constant valecity of 1.8o (a) Calculate the flux through the triangle formed by the bars-t-3.70 s. wb (b) Calculate the emf around the triangle at that time. (c) If the emf is Z = ae, where a and n are constants, what is the value of n? Math Help Intogration B over an Area 3. 10r10 points 1 Previous Answers HRw9 30 P 019 11:54 acer

Explanation / Answer

formula for magentic flux is

= BA

area of the traingle formed by the bars is

A =(1/2)(base) (height)=(1/2)(2d) (d) =d2= v2t2

= BA =B*v2t2= 0.350 T * (4.6m/s)2*(3.7 sec)2=101.38814 Wb

----------------------------------------------------------------------------------------------------

(b)

E = d/dt = d/dt ( B*v2t2) = 2Bv2t =2* 0.350 T * (4.6m/s)2*(3.7 sec)=54.8 V

(c)

E=  2Bv2t = atn

a = 2Bv2 = 2* 0.35T *(4.6m/s)2=14.81.

54.8 V=14.81 ( 3.7)^n

n = 1
