What is hydraulic pressure?

Ilia_Sergeevich [38]

Hydraulic pressure is actually the pressure that is exerted to liquid and the pressure gets transmitted throughout the liquid. Since liquid cannot be compressed, so the pressure that was exerted on the liquid gets transmitted to the walls of the container containing the liquid. This theory is applied to the braking system of cars and some other vehicles. This is known as the hydraulic pressure. It is actually the science that is concerned with the laws of movements of a fluid and the application of this theory for engineering purpose. This theory has not only been used in cars but also in planes .

Svet_ta [14]

Answer:

Hence the answer is E inside $= KQr_{1} /R^{3}$ .

Explanation:

E inside $= KQr_{1} /R^{3}$

so if r1 will be the same then

E $\begin{bmatrix}Blank Equation\end{bmatrix}$ proportional to 1/R3

so if R become 2R

E becomes 1/8 of the initial electric field.

emmasim [6.3K]

The intensity on a screen 20 ft from the light will be 0.125-foot candles.

<h3>What is the distance?</h3>

Distance is a numerical representation of the length between two objects or locations.

The intensity I of light varies inversely as the square of the distance D from the source;

I∝(1/D²)

The ratio of the intensity of the two cases;

$\rm \frac{I_1}{I_2} =(\frac{D_2}{D_1} )^2\\\\ \rm \frac{2}{I_2} =(\frac{20}{5} )^2\\\\ \frac{2}{I_2} =4^2 \\\\ I_2= \frac{2}{16} \\\\ I_2= 0.125 \ foot-candles$

Hence, the intensity on a screen 20 ft from the light will be 0.125 foot-candles
