Answer:
b. A voltage causes electric charges to move from lower to a higher potential.
Explanation:
As we know, current flows from high voltage to low voltage and the electric charge flows opposite to the direction of the current. That is why we can say that the electric charge flows from low voltage to high voltage.
Resistance does not cause the electron to flow from low voltage to high voltage.
Therefore the answer is b.
Its true hopefully this helps you.
Answer:
is the initial velocity of tossing the apple.
the apple should be tossed after 
Explanation:
Given:
- velocity of arrow in projectile,

- angle of projectile from the horizontal,

- distance of the point of tossing up of an apple,

<u>Now the horizontal component of velocity:</u>



<u>The vertical component of the velocity:</u>



<u>Time taken by the projectile to travel the distance of 30 m:</u>



<u>Vertical position of the projectile at this time:</u>



<u>Now this height should be the maximum height of the tossed apple where its velocity becomes zero.</u>


is the initial velocity of tossing the apple.
<u>Time taken to reach this height:</u>



<u>We observe that </u>
<u> hence the time after the launch of the projectile after which the apple should be tossed is:</u>
