Ask Your Teacher When a potential difference of 160 V is applied to the plates of a parallel-plate capacitor, the plates carry a
Morgarella [4.7K]

The spacing between the plates is 5.4\cdot 10^{-6} m

Explanation:

The electric field in the spacing between the plates of a parallel-plate capacitor is uniform and it is given by

E=\frac{\sigma}{\epsilon_0}

where

\sigma is the surface charge density

\epsilon_0 = 8.85\cdot 10^{-12} F/m is the vacuum permittivity

We also know that the relationship between electric field and potential difference across a parallel-plate capacitor is

V=Ed

where

V is the potential difference

d is the spacing between the plates

Combining the two equations we get

V=\frac{\sigma d}{\epsilon_0}

And given that here we have:

V = 160 V

\sigma = 26.0 nC/cm^2 = 26.0\cdot 10^{-9} C/cm^2=26.0\cdot 10^{-5} C/m^2

We can solve the equation for d, the spacing between the plates:

d=\frac{V \epsilon_0}{\sigma}=\frac{(160)(8.85\cdot 10^{-12})}{26.0\cdot 10^{-5}}=5.4\cdot 10^{-6} m

Place these bodies of our solar system in the proper order of formation.
earnstyle [38]
The four inner planets, those closest to the Sun, are Mercury, Venus, Earth, and Mars. They are smaller and composed mainly of metals and rocks. The four outer planets — Jupiter, Saturn, Uranus, and Neptune — are larger and composed mostly of gases.

Vector of magnitude 15 is added to a vector of magnitude 25. The magnitude of this sum
loris [4]

Explanation:

Given that,

Magnitude of vector A, |A| = 15

Magnitude of vector B, |B| = 25

We need to find the magnitude of this sum.

The maximum sum of the resultant vector,

R_{max}=|A_1|+|A_2|\\\\=15+25\\\\=45

The minimum sum of the resultant vector,

R_{min}=|A_1|-|A_2|\\\\=15-25\\\\=-10

So, the magnitude of this sum either 45 or -10.
