No, because for it to be kinetic energy, it's particles have to be in motion. Therefore it is potential energy
A chemical change is when a substances chemical properties change, for example, baking a cake. A physical change is when the appearance/odor/texture etc. change, for example, ice melting
Answer:
When we talk about closed economy, it means that the economy is self-sufficient. At a closed economy, no imports from the outside are brought inside a nation and no exports are sent out as well
Explanation:
The capacitance of a parallel-plate capacitor in vacuum is given by
![C= \frac{A \epsilon_0}{d}](https://tex.z-dn.net/?f=C%3D%20%5Cfrac%7BA%20%5Cepsilon_0%7D%7Bd%7D%20)
where
A is the area of each plate
d is the separation between the plates
![\epsilon_0 = 8.85 \cdot 10^{-12} F/m](https://tex.z-dn.net/?f=%5Cepsilon_0%20%3D%208.85%20%5Ccdot%2010%5E%7B-12%7D%20F%2Fm)
is the electric permittivity in vacuum
For the capacitor in our problem, the plates are circular, with a diameter of d=4.0 cm, so their radius is r=2.0 cm=0.02 m and their area is
![A=\pi r^2 =\pi (0.02 m)^2 = 1.26 \cdot 10^{-3} m^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%20%3D%5Cpi%20%280.02%20m%29%5E2%20%3D%201.26%20%5Ccdot%2010%5E%7B-3%7D%20m%5E2)
while the separation between the plates is
![d=0.50 mm=5 \cdot 10^{-4} m](https://tex.z-dn.net/?f=d%3D0.50%20mm%3D5%20%5Ccdot%2010%5E%7B-4%7D%20m)
Therefore the capacitance is

<u>According </u><u>to </u><u>Newton,</u><u> </u><u>the </u><u>bodies </u><u>in </u><u>the </u><u>universe </u><u>attract </u><u>each </u><u>other.</u><u> </u><u>This </u><u>force </u><u>if </u><u>attraction</u><u> </u><u>is </u><u>called </u><u>force </u><u>of </u><u>gravitation</u><u>.</u><u> </u> For example, the earth attracts the moon and the moon attracts the earth too. Similarly, the earth attracts the Jupiter and the Jupiter attracts the Earth.
The effect of force of attraction of a big body on a small body can be observed but that of a small body on a big one cannot be observed. The sun is so large that even the sum of the masses of all its planets and the satellites is only about 0.0015th part of mass of the sun. Due to the gravitational force between the sun and the earth, the earth keeps on moving around the sun. Similarly, the gravitational force between the satellites and planets makes the satellites to revolve around the planets. So, The gravitational force is responsible for the existence of solar system. The effect of gravitation can be experienced more on liquid than solid. Hence, we see tides in the sea and ocean due to the force of gravitation of the moon and the sun on the earth when they lie on the same straight line.
