Assuming that what you typed meant 20 seconds, rather than 2o seconds, the car is travelling at a velocity of 200 meters per second.
Answer:
A = -0.576 μC
B = 4.256 μC
Explanation:
Suppose a single electron charge is 
. Then the total charge that is flowing from B to A is:
Let A and B be the initial charge of spheres A and B, respectively. Since the net charge is 3.68μC we have the following equation
(1)
When they touch 2.416μC flows from B to A, then they are equal, so we have the following equation
(2)
Add equation (1) to equation (2) we have
For future reference, It is going to be kind of difficult for people to give you a direct answer without the options, but I found the questions options else where.
"If you stop working out and eating for a few days, you'll probably fit." Would be the correct answer.
I believe the answer is "radioactive decay".
Explanation:
When something is moving, we call it is in motion. It can be also defined as a change of position in relation to another object.
When an object is not moving at all, we call that it was at rest.
To be in motion, there must be a change in position.
Hence, the correct options are "a change of position in relation to another object" and "something is moving".
