In the region of space shown in the diagram, there is a uniform magnetic field of strength 0.128 T in the direction of the +z axis. What is the magnetic flux across the surface abcd?

A. 0.0115 Wb
B. 0.000 Wb
C. 0.0230 Wb
D. 0.0512 Wb

Plss anybody know how to do this? ? i need the answers from a through d

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
