A 0.106-A current is charging a capacitor that has square plates 4.60 cm on each side. The plate separation is 4.00 mm.

nikdorinn [45]

Answer:

$\frac{d \phi_{E}}{dt} =1.1977 *10^{10} \ V\cdot m/s$

$I = 0.106 \ A$

Explanation:

From the question we are told that

The current is $I = 0.106 \ A$

The length of one side of the square $a = 4.60 \ cm = 0.046 \ m$

The separation between the plate is $d = 4.0 mm = 0.004 \ m$

Generally electric flux is mathematically represented as

$\phi_E = \frac{Q}{\epsilon_o}$

differentiating both sides with respect to t is

$\frac{d \phi_{E}}{dt} = \frac{1}{\epsilon_o} * \frac{d Q}{ dt}$

=> $\frac{d \phi_{E}}{dt} = \frac{1}{\epsilon_o} *I$

Here $\epsilon_o$ is the permitivity of free space with value

$\epsilon _o = 8.85*10^{-12} C/(V \cdot m)$

=> $\frac{d \phi_{E}}{dt} = \frac{0.106}{8.85*10^{-12}}$

=> $\frac{d \phi_{E}}{dt} =1.1977 *10^{10} \ V\cdot m/s$

Generally the displacement current between the plates in A

$I = 8.85*10^{-12} * 1.1977 *10^{10}$

=> $I = 0.106 \ A$

New stars form from ?

allsm [11]

Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the sun

A car traveling at 40 m/s starts to decelerate steadily. It comes to a complete stop in 5 seconds. What is its acceleration? m/s

SCORPION-xisa [38]

Acceleration =

   (change of speed) / (time for the change).

Change of speed = (speed at the end) - (speed at the beginning)

      =    ( zero ) - (40 m/s)

   = -40 m/s .

Acceleration = (-40 m/s) / (5 seconds)

   = -8 m/s² .

Learning Task 3: Read the characteristics of mixtures given in the second column. Identify if it is homogeneous or heterogeneous

madreJ [45]

1. Components can be separated by physical means [heterogenous]

2. The additive component is so finely dispersed in the main ingredient such that it can't be seen [homogenous]

3. Particles are uniformly distributed [homogenous]

4. The substances are identified in different phases [heterogenous]

5. Particles are non-uniformly distributed [heterogenous]

A homogenous mixture is a type of mixture in which the composition is uniform throughout the mixture.

Characteristics of a homogenous mixture:

the mixture is uniform
the composition is the same
it consists of one phase

A heterogenous mixture is a type of mixture in which the composition of the mixture is not uniform

Characteristics of heterogenous mixture include;

it contains two or more ingredients or phases.

different phases mixed together, which are physically separated

samples obtained from different parts of the mixture may have a different composition

In the given characteristics of the mixture in the question we can classify them as follows;

1. Components can be separated by physical means --heterogenous

2. The additive component is so finely dispersed in the main ingredient such that it can't be seen --- homogenous

3. Particles are uniformly distributed ---- homogenous

4. The substances are identified in different phases ---- heterogenous

5. Particles are non-uniformly distributed ---- heterogenous
