1. if the strength of the magnetic field at a is 64 units, the strength of the magnetic field at b is

a. 16 units
b. 32 units
c. 128 units
d. 256 units

2. if the strength of the magnetic field at b is 6 units, the strength of the magnetic field at a is

a. 1.5 units
b. 0.75 units
c. 24 units
d. 10.6 units

1. The strength of magnetic field at A is 64 unit, then the magnetic field strength at B. is 256 units.

64 × 64 = 256 units.

2. If the strength of magnetic field B is 6 units then the strength magnetic field at A is 24 units.

which is 256 : 4 = 16 units.

Magnetic field is one of the two ways where the intensity of magnetic field is being expressed.

the answer is "a.) well–developed vascular system."

explanation:

substitution is the answer in this case
