Answer from: daltonrebekah3532

ya thats right

Explanation:

here is one explanation i found on the web:

The true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".

Explanation:

The electric force is due to the forces acting between the charges. The magnetic force is the force exerted between the magnets or moving charged particles.

The electromagnetic force is created by the magnetic field and the electric field.

The magnetic force is related to the electric force. These forces are different aspects of single electromagnetic force. The moving charge produce the magnetic force. The moving magnet produce the electric forces. The interplay of electric field and the magnetic force is the basis for motor.

Motor converts the electrical energy into mechanical energy. The operation of a motor depends on the relationship between electric and magnetic forces.

Therefore, the true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".

Answer from: Quest

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

Answer from: Quest

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

$^{m}_{4}x$ and $^{m}_4y$

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

$^{m}_{5}x^{-}$

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be $^{9}_{5}be^{-}$ and $^{9}_{4}be$ .

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
