Answer:

The positively charged ball moves between both charged plates till the plates and the ball all become neutral.

Check Explanation for more.

Explanation:

Let the ball be in square brackets, and the plates in normal brackets.

(+) [+] (-)

From the law that like charges repel and unlike charges attract.

The positive ball would go first to the negatively charged plate. After which, the ball would hold more negative charges overall than before.

Because the ball is now more negatively charged, it then travels towards the positive plate. In the same manner, the ball would transfer negative electrons to the positive plate.

So, when leaving the positive plate, the ball would be more positive and be drawn towards the negative plate once more. In doing so, it would make the negative plate more positive.

Then, the ball again holds more negative electrons and is drawn towards the positive plate once more.

This back and forth process continues until the once-positive and once-negative plates become neutral, that is, they are discharged.

The ball hanging on the insulated thread becomes neutral too at this point.

Hope this Helps!!!

There are 3600 in a full circle. a. How many arcminutes are in a full cycle? b. How many arcseconds are in a full cycle?

liberstina [14]

Answer:

21600

1296000

Explanation:

Full cycle consists of

$360^\{circ}$

1 hour = 3600 seconds

1 minute = 60 seconds

Converting to arcminutes

$360\times 60=21600\ arcseconds$

The arcminutes in a full cycle is 21600

Converting to arcseconds

$360\times 60\times 60=1296000\ arcseconds$

The arseconds in full cycle is 1296000

Two unknown resistors are connected together. When they are connected in series their equivalent resistance is 15 Ω. When they a

DochEvi [55]

Explanation:

Let x and y are two unknown resistors. When they are connected in series their equivalent resistance is 15 Ω. When they are connected in parallel, their equivalent resistance is 3.3 Ω.

For series combination,

$x+y=15$ ......(1)

For parallel combination,

$\dfrac{1}{x}+\dfrac{1}{y}=3.3$ ....(2)

We need to find the resistances of these resistors. Solving equation (1) and (2) we get :

x = 0.29 and y = 14.7

Hence, the resistances of these resistors are 0.29 ohms and 14.7 ohms.

a bus travels 4 km due north and 3 km due west going from bus station a to bus station b. the magnitude of the bus displacement

ladessa [460]

Answer:

5km

Explanation:

Magnitude of displacement is found by getting the resultant. Resultant is same as the bypotenuse hence

$R=\sqrt {{x^{2}+y^{2}}$ where x is the displacement in west direction and y is displacement in North direction. Substituting x with 3km and y with 4 km then

$R=\sqrt {{3^{2}+4^{2}}=5km$

If an electromagnetic wave has a frequency of 6 x 105 Hz, what is its

Ber [7]

Answer:

500 m

Explanation:

Applying,

v = λf.................... Equation 1

Where v = speed of light, λ = wave length, f = frequency of light.

make λ the subject of the equation

λ = v/f............... Equation 2

From the question,

Given: v = 3×10⁸ m/s, f = 6×10⁵ Hz

Substitute these values into equation 2

λ = 3×10⁸/6×10⁵

λ = 500 m
