The particle, initially at rest, is acted upon only by the electric force and moves from point a to point b along the x-axis, increasing its kinetic energy by 1.44ã—10^(−18) j. in what direction and through what potential difference vb-va does the particle move? a. the particle moves to the left through a potential difference of vb-va = 0.500 v. b. the particle moves to the left through a potential difference of vb-va = -0.500 vc. the particle moves to the right through a potential difference of vb-va = 0.500 v. d. the particle moves to the right through a potential difference of vb-va = -0.500 v. e. the particle moves to the left through a potential difference of vb-va = 5.00 v. f. the particle moves to the right through a potential difference of vb-va = -5.00 v.

the closer the planet is to the sun, the larger the gravity

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
