navik [9.2K]

Answer:

It's not enough.

Explanation:

To be able to separate mixtures into substances we have more methods than just distillation, filtration and evaporation. Certain mixtures cannot be filtered, however by decanting can be separated simpler substances from it. Centrifugation separates solids dispersed in liquids that cannot be separated by filtration. Also, it is necessary to try to separate the substance by the method of chromatography, crystallization, etc.

Have a nice day!

Many types of decorative lights are connected in parallel. If a set of lights is connected to a 110 V source and the filament of

Oksi-84 [34.3K]

Answer:

i₀ = V / R_i

Explanation:

For this exercise we use Ohm's law

V = i R

i = V / R

the equivalent resistance for

$\frac{1}{R_{eq}}$ = ∑ $\frac{1}{R_i}$

if all the bulbs have the same resistance, there are N bulbs

$\frac{1}{ R_{eq}} = \frac{N}{R_i}$

R_{eq} = R_i / N

we substitute

i = N V / Ri

where i is the total current that passes through the parallel, the current in a branch is

i₀ = i / N

i₀ = V / R_i

Which of the following are equivalent units?

asambeis [7]

Answer : The correct options are, (B) a newton-meter and a joule and (C) a newton and a joule/sec

Explanation :

As we know that,

$1N=1Kg\text{ m }s^{-2}\\\\1J=1\text{Kg }m^2s^{-2}\\\\1W=1\text{Kg }m^2s^{-3}$

or we can say that,

$1W=1J/s\\\\1J=1Nm\\\\1N=1J/s\\\\1W=1Nms^{-1}$

From the given options, the option B and C are the equivalent units.

Hence, the correct options are, (B) and (C)

A vector A makes an angle of 20 degree and B makes an angle of 110 degree with the x-axis. The magnitude of this vectors are 3 m

Fofino [41]

The resultant is 5 m at $73.1^{\circ}$

Explanation:

To solve the problem, we have to resolve each of the two vectors into its component along the x-axis and the y-axis.

Vector A has magnitude 3 m and angle 20 degrees with the x-axis, so its components are

$A_x = A cos \theta = (3)(cos 20)=2.82 m$

$A_y = A sin \theta = (3)(sin 20)=1.03 m$

Vector B has magnitude 4 m and angle 110 degrees, so its components are

$B_x = B cos \theta = (4)(cos 110)=-1.37 m$

$B_y = B sin \theta = (4)(sin 110)=3.76 m$

So, the x- and y- components of the resultant vector are

$R_x = A_x + B_x = 2.82+(-1.37)=1.45 m\\R_y = A_y+B_y = 1.03+3.76 =4.79 m$

Therefore the magnitude of the resultant is

$R=\sqrt{R_x^2+R_y^2}=\sqrt{(1.45)^2+(4.79)^2}=5.0 m$

While the direction is given by

$\theta=tan^{-1}(\frac{R_y}{R_x})=tan^{-1}(\frac{4.79}{1.45})=73.1^{\circ}$
