Answer:
The surface charge density on the plate,
Explanation:
It is given that,
Area of parallel plate capacitor,
Separation between the plates,
Electric field between the plates,
We need to find the surface charge density on the plates. The formula for electric field is given by :
Where
= surface charge density
Hence, this is the required solution.
"Mass" is the amount of matter that makes up your body. It doesn't depend on where you happen to be, any more than the amount of money in your pocket depends on where you are. If your mass is 65 kg in your kitchen, then it's 65 kg. Doesn't matter whether you're in the basement, in school, at the bottom of the ocean, in Mexico, in China, anywhere else on Earth, anywhere on the moon, or floating in space.
Wavelength = 1/frequency thus wavelength =1/30000
First you must calculate the speed of Amy and speed of Bill.
Now calculate the difference between Bill's speed and Amy's speed.
Amy's average speed is not faster. Bill's average speed is faster than Amy's by 6 m/sec.
Hope this helps.

Answer:
0.08 ft/min
Explanation:
To get the speed at witch the water raising at a given point we need to know the area it needs to fill at that point in the trough (the longitudinal section), which is given by the height at that point.
So we need to get the lenght of the sides for a height of 1 foot. Given the geometry of the trough, one side is the depth <em>d</em> and the other (lets call it <em>l</em>) is given by:
since the difference between the upper and lower base is the increase in the base and we are only at halft the height.
Now we can calculate the longitudinal section <em>A</em> at that point:
And the raising speed <em>v </em>of the water is given by:
where <em>q</em> is the water flow (1 cubic foot per minute).
