It's true charged particles are always acted on by an electric field.when the velocity of the electron is parallel to the magnetic field, the magnetic force vanishes.
Answer:
The Angle between the vector A and B is 12.32°
Explanation:
Given data
|A×B|=32
|A|=10
|B|=15
To find
Angle α
Solution
From Cross product properties we know that

The Angle between the vector A and B is 12.32°
The cycle of cellular respiration and photosynthesis are important for the life of plants because cellular respiration uses one of the products of photosynthesis (oxygen), and uses it as one of the reactants along with glucose to produce carbon dioxide. These two cycles help maintain a balance for our atmosphere, even though pollution and other factors have disrupted this balance. Hope this helps! :)
Power = (work done) / (time to do the work)
Power = (2000 J) / (5 sec)
<em>Power = 400 watts</em>
The correct answer is A) <span>The two magnetic fields repel each other, causing the train to levitate, or hover, above the rails.
In fact, same magnetic poles repel each other, while opposite magnetic poles attract each other. the magnets on bottom of the train and on top of the railway have the same polarities, so they repel each other and this allows the train to levitate.
