A metal cube with sides of length a is moving at velocity v⃗ =v0j^ across a uniform magnetic field b⃗ =b0k^. The cube is oriented so that four of its edges are parallel to its direction of motion (i. E. , the normal vector of two faces are parallel to the direction of motion). (figure 1).

The answer is : v = 55 + 8m plug in m = 25 v = 55 + 8(25) = 255 25 minutes after baxter begins filling the tank, the volume of water in the tank will be 255 gallons. slope: m = 8 gal/min for every min the water is on, the volume of water in the tank increases by 55 gallons. y-intercept: 55 (0,55) the initial volume of water in the tank was 55 gallons.

Ibelieve the correct answer is c
