Physics pl 12)a body goes from p to q with a velocity of 10 m/s and comes back from q to p with a velocity of 20 m/s. what is the average velocity of the body during the entire trip? a)0 m/s b)13 m/s c)10 m/s d)15 m/s

velocity = displacement / time

displacement measures how far the ending point is from the starting position. If the object returns to its original position, displacement will be 0 m.

In the question, the object starts at P and returns to P, so displacement equals 0 m. Thus, no matter how long the travelling time is, the average velocity is also 0 m/s.

So, the ans is A.

what type of charge does it have? negative

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
