Answer:
Explanation:
Given
Diameter(D)=21.5 cm
distance between plate=1.75 mm
and we know capacitance is
and we know charge is
Q=CV
and charge density (![\sigma [tex])[tex]=\frac{Q}{A}=\frac{\epsilon _0AV}{Ad}=\frac{\epsilon V}{d}](https://tex.z-dn.net/?f=%5Csigma%20%5Btex%5D%29%5Btex%5D%3D%5Cfrac%7BQ%7D%7BA%7D%3D%5Cfrac%7B%5Cepsilon%20_0AV%7D%7BAd%7D%3D%5Cfrac%7B%5Cepsilon%20V%7D%7Bd%7D)
Electric field(E)
Energy density
Energy desity
Energy desity![=\frac{1}{8\pi \cdot 9\times 10^9}\times \left [ \frac{12\times 10^3}{1.75}\right ]^2](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B8%5Cpi%20%5Ccdot%209%5Ctimes%2010%5E9%7D%5Ctimes%20%5Cleft%20%5B%20%5Cfrac%7B12%5Ctimes%2010%5E3%7D%7B1.75%7D%5Cright%20%5D%5E2)

real world examples
Explanation:
concave wave rock- The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history. --Also, volcanic eruptions have changed earth greatly. EX- Ash and sulfur went into Earth's atmosphere because of the Tambora eruption which dimmed incoming sunlight. It lowered global temperatures by about 3°F. The Mount Pinatubo of 1991 that erupted in the Philippines cooled the planet by about 1°F.
Answer : The correct degree of precision is 272.94 g.
Explanation :
Precision : It is defined as the closeness of two or more measurements to each other.
For Example: If you weigh a given substance five times and you get 2.7 kg each time. Then the measurement is said to be precise.
Level of precision is determined by the maximum number of decimal places.
In the given figure, the value of mass of object is 280 g. From the given options we conclude that the 272.94 g is more close to 280 g and has maximum number of decimal places. So, 272.94 g measurement is said to be precise.
Therefore, the correct degree of precision is 272.94 g.
