<span>Operant conditioning by Burrhus Frederick Skinner, showed that people learn to behave in certain ways because of reinforcement. This a product of a psychology school of thought, behaviorism, which comes in the notion that whatever a person behave is what matters instead of his mind, pioneered by John B. Watson. If a person wants to retain the behavior, then he will do positive reinforcements example, positive stroking. If the behavior is undesired and needs to be exterminated, then a punishment will be instilled.</span>

Two large, parallel, nonconducting sheets of positive charge face each other. What is at points (a) to the left of the sheets, (

alexira [117]

Answer:

a)The electric Field will be zero at the point between the sheets

b) $E_1=\dfrac{\sigma}{\epsilon_0}$

c) $E_2=\dfrac{\sigma}{\epsilon_0}$

Explanation:

Let $\sigma$ be the surface charge density of the of the non conducting parallel sheet.Let consider a Gaussian surface in the form of of cylinder such that its cross-sectional is A . Then there will be flux only due to cross sectional area as the curved sectional is perpendicular to the the electric field so the Electric Flux due to it is zero.

Now using Gauss law we have, E be the electric Field at the distance r from the sheet then

$E\times 2A=\dfrac{\sigma A}{\epsilon_0}\\E=\dfrac{\sigma}{2\epsilon_0}$

The Field will be away from the sheet and perpendicular to it.

a) The Electric Field between them

$E_1=\dfrac{\sigma}{2\epsilon_0}-\dfrac{\sigma}{2\epsilon_0}\\=0$

b)The Electric Field to the right of the sheets

$E_1=\dfrac{\sigma}{2\epsilon_0}+\dfrac{\sigma}{2\epsilon_0}\\=\dfrac{\sigma}{\epsilon_0}$

c)The Electric Field to the left of the sheets

$E_2=\dfrac{\sigma}{2\epsilon_0}+\dfrac{\sigma}{2\epsilon_0}\\=\dfrac{\sigma}{\epsilon_0}$

The red LED consists of a white LED covered with a red filter. What does the red filter do?

telo118 [61]

White light is light that's made up of ALL colors.

If you have a source of white light and you want red light,
then you have to REMOVE all the other colors from the
white light somehow.

That's what a red filter does. The dye in the filter has chemicals
that absorb every color of light except red. Then, red light is the
only thing left to come out of the other side.

(If the light going into the filter had no red in it, then the filter
would appear black, because there wouldn't be any light
coming out of it at all.)

Two objects perform the same task. One has thousands of moving parts while the other has no moving parts. What are they?.

Natalka [10]

The two objects perform the same task of measuring time and they are hourglass and sundial.

<h3>What is an hourglass?</h3>

An hourglass is a device used to measure the passage of time.

The hourglass contains two glass bulbs connected vertically by a narrow neck that allows a regulated flow of a substance from the upper bulb to the lower one.

<h3>What is a sundial?</h3>

A sundial is a horological device that is used to measure time of the day when there is sunlight by the apparent position of the Sun in the sky. Unlike hourglass, its doesn't move.

Thus, the two objects perform the same task of measuring time and they are hourglass and sundial.
