1. Magnetic properties of a substance depends on the structure of its valence electrons. It has something to do with orbitals so I suggest you study about molecular geometry of a compound/substance firstIt's the way a substance's atoms fit together, being pulled and pushed from all sides equally. exists in metallic bonds if a substance is said to be magnetic, it is simply attracted by a magnet. if it is paramagnetic, it is repelled by a magnet.

2.The magnetic field will be perpendicular to the electric field and vice versa An electric field is the area which surrounds an electric charge within which it is capable of exerting a perceptible force on another electric charge. A magnetic field is the area of force surrounding a magnetic pole, or a current flowing through a conductor, in which there is a magnetic flux. A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid. The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles. The electrostatic force between charged particles is an example of this relationship.

it takes a hose 4 minutes to fill a rectangular aquarium 9 inches long, 13 inces wide, and 14 inces tall. how long will it take

Studentka2010 [4]

Answer: 43.58 min

Explanation:

Knowing the volume of a rectangular object is length x width x height, we have two volumes:

$V_{1}=(9 in)(13 in)(14 in)=1638 in^{3}$

$V_{2}=(21 in)(25 in)(34 in)=17850 in^{3}$

And we know it takes a time of 4 minutes to fill $V_{1}$ .

If we want to know how long will it take the same hose to fill another tank with volume $V_{2}$ , we can use the Rule of three, which is a mathematical rule to find out an amount that is with another quantity given in the same relation as other two also known:

$1638in^{3}$ ---- $4min$

$17850in^{3}$ ---- $?$

$?=\frac{(17850 in^{3})(4min)}{1638 in^{3}}$

Finally:

$?=43.58 min$
