Answer:
Drop to half of the previous value
Explanation:
Energy stored in capacitor is inversly propotional to the distance between the plates.
Answer:
The larger pebble has 25 times more mass.
Explanation:
To solve the exercise it is necessary to apply the work and energy conservation equations.
For the case described, the work done must be preserved and must be the same, that is,

By definition work linked to the conservation of kinetic energy would be given by






The ratio between the mass and the velocity would be,



Therefore the answer is: The larger pebble has 25 times more mass.
Outer planets are farther away and made up of gases. Inner planets closer. It's pretty much self explanatory. Hope this helps.
Ahhh, there aren’t option to work with :v
Try writing them down here thnx
The correct answer is "an attractive force" between the wires.
Let's see why. Assume we have wire A on the left and wire B on the right, and that the current in both wires go upward. First, let's find the direction of the magnetic field produced by wire A at wire B: by using the right-hand rule, we see that since the current (the thumb) goes upward, the magnetic field (given by the other fingers) at wire B is directed inside the paper.
Then we can apply again the right-hand rule to see what is the force on wire B. The index gives the direction of the current (upward), the middle finger the direction of the magnetic field (inside the paper), and the thumb gives the direction of the force: to the left, so toward wire A. This means the force is attractive. (you can re-do the procedure on wire A, and you will find the force on wire A is directed toward wire B)
