The answer would be:
Houlette de berger.
Answer:
Separation between the plates, area of the plates and dielectric constant
Explanation:
The capacitance of a parallel plate capacitor is given by:
where
k is the dielectric constant
is the vacuum permittivity (which has a constant value)
A is the area of the plates
d is the separation between the plates
Therefore from the formula we see that the capacitance of a parallel plate capacitor depends on the following factors:
- Separation between the plates
- Area of the plates
- Dielectric constant
Answer:
m = 369 grams
Explanation:
Given that,
The density of backpack, d = 30 g/mL
The volume of the backpack, V = 12.3 cm³
We need to find the mass of the backpack. The density of an object is given by :
So, the mass of the backpack is 369 grams.
a). is true. <span>All motion is relative to a frame of reference. That's a fancy
way of saying that whenever you talk about a distance, an acceleration,
or a speed, they're always compared to something. Many surprising
things come out of this:
-- There's no such thing as "how fast is it <u>really</u> moving".
-- There's no such thing as "how high is it <u>really</u>".
-- There's no such thing as "<u>really</u> moving" or "<u>really</u> at rest".
What about quantities where you use distance or motion to calculate them ?
Like . . . . .
Potential energy . . . . . (mass) x (gravity) x (<u>height</u>)
Kinetic energy . . . . . (1/2) (mass) (<u>speed</u>)²
Momentum . . . . . (mass) x (<u>speed</u>) .
Yep, that's right. Those things are all relative to a frame of reference too;
different observers can get different answers,and they're all correct ... for
their own frame of reference.
Simple example:
You're flying in a passenger jet to visit your grandma.
In the frame of reference of somebody on the ground, you're moving at
400 miles per hour.
In the frame of reference of the pilot or the person sitting next to you,
you are at rest, and you can listen to your pod or read a book ... (or
maybe you're <em>heavily</em> at rest and taking a nap :-).)

Current = (charge) / (time) = (2.5) / (0.0002) = <em>12,500 Amperes</em>
The only thing wrong with the answer "12500" is that it lacks a unit.
