<span>So we want to know if it is true or false that The Oort clout is a large collection of comets that surrounds the Solar system. The Oort cloud is roughly a spherical shell that surrounds the Solar system and it mostly consists of icy objects and it is the source of the most of the long term comets that have been observed. So the answer is TRUE. </span>

A capacitor is constructed of two large, identical, parallel metal plates separated by a small distance d. A battery fully charg

Alja [10]

The capacitance of a capacitor of a parallel plate is given by:

$C=\frac{kA\cdot\epsilon_o}{d}$

Where:

$\begin{gathered} \epsilon_o=_{\text{ }}Vacuum_{\text{ }}permittivity \\ k=_{\text{ }}Dielectric_{\text{ }}constant=2 \\ A=_{\text{ }}Area_{\text{ }}of_{\text{ }}the_{\text{ }}plates \\ d=_{\text{ }}distance_{\text{ }}betwen_{\text{ }}the_{\text{ }}plates \end{gathered}$

We also know:

$\begin{gathered} Q=\frac{q}{V} \\ so\colon \\ \frac{q}{V}=\frac{kA\cdot\epsilon_o}{d} \\ V=\frac{qd}{kA\cdot\epsilon_o} \\ if \\ k=2 \\ V=\frac{1}{2}(\frac{qd}{kA\cdot\epsilon_o}) \end{gathered}$

As we can see the voltage halves

And since:

$\begin{gathered} E=\frac{V}{d} \\ W=qV \end{gathered}$

We can conclude that electric field and also the energy halve

Two students, Nora and Allison, are both the same age when Allison hops aboard a flying saucer and blasts off to achieve a cruis

White raven [17]

Answer:

23.38 years

Explanation:

Speed of Allison = 0.83 c = v

Time passed according to Allison = Δt = 29.5 years

Time dilation

$\Delta t'=\frac{\Delta t}{\sqrt{1-\frac{v^2}{c^2}}}\\\Rightarrow \Delta t'=\frac{29.5}{\sqrt{1-\frac{0.83^2c^2}{c^2}}}\\\Rightarrow \Delta t'=\frac{29.5}{\sqrt{1-0.83^2}}\\\Rightarrow \Delta t'=52.88\ years$
