Which refers to the ends of a magnet where the forces are strongest? A) attracting forces
B) opposing forces
C) magnetic fields
D) magnetic poles

Magnetic Pole. The ends of a magnetic object, where the magnetic force is strongest. Any magnet, no matter what its shape, has two ends, each one called a magnetic pole

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
