Aboat is moving due east in a region where the earth's magnetic field is 5.0 × 10^5n/am due north and horizontal. the boat carries a vertical aerial 3m long. if the speed of the boat is 2.50 m/s, what is the magnitude of the induced emf in the wire of aerial?
a. 3.75 × 10^-4 v
b. 3.75 × 10^-4 mv
c. 375 × 10^-4 v
d. 1 mv
e. none of the above

double the distance = divide strength by 4

its c i just checked it

a.   mass number from atomic number

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
