Answer:

These destructive frequencies entrain the thoughts towards disruption, disharmony, and disunity. Additionally, they also stimulate the controlling organ of the body — the brain — into disharmonious resonance, which ultimately creates disease and war.

Answer:

Electric field, E = $6.36\times 10^{6}\ V/m$

Explanation:

Given that,

The potential difference across the membrane, $\Delta V=0.063\ V$

The thickness of the membrane is, $\Delta x=9.9\times 10^{-9}\ m$

We need to find the magnitude of the electric field in the membrane. We know that the relation between electric field and electric potential is given by :

$E=\dfrac{-\Delta V}{\Delta x}\\\\E=\dfrac{0.063\ V}{9.9\times 10^{-9}\ m}\\\\E=6.36\times 10^{6}\ V/m$

So, the magnitude of the electric field in the membrane is $6.36\times 10^{6}\ V/m$ .

how long does it take a car to accelerate from 3.4m/s to 20.9m/s if the average acceleration is 6.0m/s (squared).

Gre4nikov [31]

Average acceleration is the ratio of the change in velocity to the time it takes for that change to occur:

$a_{\mathrm{av}}=\dfrac{\Delta v}{\Delta t}$

We want to find $\Delta t$ :

$6.0\,\dfrac{\mathrm m}{\mathrm s^2}=\dfrac{20.9\,\frac{\mathrm m}{\mathrm s}-3.4\,\frac{\mathrm m}{\mathrm s}}{\Delta t}$

$\implies\Delta t=2.9\,\mathrm s$

In the Electromagnetic Force, opposite charges will ________.

kiruha [24]

-- Charges with the same sign repel each other.

-- Charges with different signs attract each other.

-- This is called the "electrostatic force".

-- There's another set of forces called "magnetic forces", but

-- there's no such thing as "electromagnetic force".
