Answer:
J Two objects carry initial charges that are qi and q2, respectively, where |q2| > |qi|. ... [45 ptsj A particle is uncharged and is thrown vertically upward from ground level with a ... The particle is then given a positive charge +q and reaches the same maximum height h when thrown vertically upward with a speed of 40.0 m/s.
Explanation:
Answer:
<u><em>375 J</em></u>
Explanation:
<u><em>Total energy</em></u> = 750 J
<u><em>Efficiency</em></u> = 50%
<u><em>Wasted energy</em></u> = 50% [100% - 50%]
<u><em>Amount of wasted energy</em></u>
= 750 x 50%
= 750 x 0.5
= 375 J
The similarity between electric field and magnetic field is that both fields attract or repel charges in the field.
<h3>What is electric field?</h3>
An electric field is a region of space that surrounds electrically charged particles and exerts force on other charged particles within the filed.
<h3>What is magnetic field?</h3>
A magnetic field is a vector field that describes the magnetic influence on moving electric charges.
<h3>Similarity between electric field and magnetic field</h3>
The similarity between electric field and magnetic field is that both fields attract or repel charges in the field.
