An electroscope is a device that has small gold foil strips suspended from a metal rod. A student brings a negatively charged ro

d near the top of a neutral electroscope. The student then briefly touches a hand to the top of the electroscope before removing the charged rod. The foil strips of the electroscope now spread apart. The student then brings a different rod near the top of the electroscope. The leaves of the electroscope move closer together (see below). The new rod must have a net charge that is
1) positive.
2) negative.
3) neutral.
4) not enough information.

If a car races around a 2.3 mile oval track 220 times, what is the displacement of the car in meters when it crosses the finish
Wewaii [24]

Answer: 0 miles.

Explanation:

First let's define what the displacement is:

The displacement is defined as the difference between the final position and the initial position.

So, if for example, you start at your house, then go to a store, and then go back to your house, your total displacement will be zero, because the initial position and the final position are the same.

Then when the car reaches the final line, it will be in the same place that it started (because this is an oval track, so the finish line connects with the starting point)

Then the total displacement is 0miles.

You and your dog are walking along a pond. Your dog looks into the still water and is startled to see its reflection. Which phen
attashe74 [19]

You just identified the image as a "reflection", so it's a pretty good bet that
the phenomenon involves reflection somehow.

Your dog can see his reflection in a mirror inside the house just as easily
as in the surface of the pond.  My dogs do it all the time.  The phenomenon
doesn't require water.

It's reflection of light waves.
