"D. Magnetic and electrical forces are similar because they are both related to the interactions between charged particles" best describes how the forces relate.
Two copper spheres are currently 1.2 meters apart. One sphere has a charge of +2.2•10-4 C and the other has a charge of -8.9•10-4 C, then the the force between the charged spheres is the force attractive.
<h3>What is Coulomb's law?</h3>
Coulomb's law can be expressed as that the electrical force between two charged bodies is directly proportional to the product of the quantity of charge on the bodies and inversely proportional to the square of the separation distance between the two bodies.
As given in the problem two copper spheres are currently 1.2 meters apart.One sphere has a charge of +2.2•10-4 C and the other has a charge of - 8.9•10-4 C.
As per coulomb's law, opposite charges attract each other.
Thus, If one sphere has a charge of +2.2•10-4 C and the other has a charge of -8.9•10-4 C, then the the force between the charged spheres is the force attractive.

Answer:
887.1Hz
Explanation:
Given parameters:
Speed of sound wave = 330m/s
Wavelength = 0.372m
Unknown:
Frequency = ?
Solution:
To solve this problem, we use the expression below:
Speed = Frequency x wavelength
330 = Frequency x 0.372
Frequency = 887.1Hz
Diagram A shows two laser beams, one blue and one red, that are incident on a mirrored surface. Diagram B shows two laser beams, one blue and one red, that are incident on a transparent block of glass then The blue and red laser beams reflect at the same angle, and they refract at different angles.
A laser emits a very focused beam of light that can be used in a variety of equipment and technologies. Light Amplification by Stimulated Emission of Radiation is what the letters in the term laser stand for. The word "laser" is an acronym for "Light Amplification by Stimulated Emission of Radiation." In a laser beam, the light waves are "coherent," which means they are all traveling at the same speed and wavelength. To do this, excited electrons are passed through an optical "gain medium," which could be a solid substance like glass or a gas.
