Question
I need help with the following 3 physics questions. There is a figure that goes with this which you should be able to picture from the description. I tried to upload the image but I had errors. Anyways, any help would be appreciated and PLEASE explain your calculations.
A rectangular loop of area 0.16 m^2 is placed in a region where the
magnetic field is perpendicular to the plane of the loop. In the figure
to the right, the magnetic field is directed out of the plane. For times
t<0, the magnetic field has the constant value of 0.350 T and for times
t>0, the magnetic field varies in time according to the expression
B(t) = 0.35e^(-0.5t) where t is expressed in seconds and B(t) is expressed
in tesla.
44. What is the magnitude of the induced emf in the loop at time 2.00 st=?
(A) 1.03*10^-2 V
(B) 1.33*10^-2 V
(C) 1.81*10^-2 V
(D) 2.12*10^-2 V
(E) 2.43*10^-2 V
45. What is the direction of the induced current in the loop for times t>0?
(A) clockwise
(B) counter-clockwise
46. What is the magnitude of the maximum emf induced in the loop?
(A) 2.6*10^-2 V
(B) 2.8*10^-2 V
(C) 3.00*10^-2V
(D) 3.2*10^-2 V
(E) 3.4*10^-2 V
Explanation / Answer
44)(B) 1.33*10^-2 V 45)(A) clockwise 46)(C) 3.00*10^-2V
