Answer:

In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

The charge density of a uniformly charged disk 0.420 m in diameter is 2.92 ✕ 10−2 C/m2. What is the magnitude of the electric fi

iragen [17]

Answer:

E = {(Charge Density/2e0)*(1 - [z/(sqrt(z^2 - R^2))]}

R is radius = Diameter/2 = 0.210m.

At z = 0.2m,

Put z = 0.2m, and charge density = 2.92 x 10^-2C/m2, and constant value e0 in the equation,

E can be calculated at distance 0.2m away from the centre of the disk.

Put z = 0.3m and all other values in the equation,

E can be calculated at distance 0.3m away from the centre of the disk

Water is flowing in a fire hose with a velocity of 1.0 m/s and a pressure of 200000 Pa. At the nozzle the pressure decreases to

jeka57 [31]

Answer:

The velocity is $v_n =14.09 \ m/s$

Explanation:

From the question we are told that

The velocity of the water in the pipe is $v_i = 1.0 \ m/s$

The pressure inside the pipe is $P_i = 200000 \ Pa$

The pressure at the nozzle is $P_n = 101300 \ Pa$

The density of water is $\rho = 1000 \ kg / m^3$

For the height $h_1 = h_2 = h$

where $h_1$ is height of water in the pipe

and $h_2$ is height of water at the nozzle

Generally Bernoulli equation is represented as

$\frac{1}{2} \rho * v_i ^2 + \rho * g * h_1 + P_i = \frac{1}{2} \rho v_n ^2 + \rho * g* h_2 + P_n$

=> $\frac{1}{2} \rho * v_i ^2 + \rho * g * h + P_1 = \frac{1}{2} \rho v_n ^2 + \rho * g* h + P_2$

Where $v_n$ is the velocity of the water at the nozzle

Now making $v_n$ the subject

$v_n = \sqrt{\frac{2}{\rho} [ P_i - Pn + \frac{1}{2} \rho v_i^2}$

substituting values

$v_n = \sqrt{\frac{2}{1000} [ 200000 - 101300 + \frac{1}{2} (1000 * (1.0)^2)}$

$v_n =14.09 \ m/s$
