Two isolated copper plates, each of area 0.40 m2, carry opposite charges of magnitude 7.08 × 10-10 C. They are placed opposite e

ach other in parallel alignment, with a spacing of 4.0 cm between them. What is the potential difference between the plates? (ε0 = 8.85 × 10-12 C2/N ∙ m2)

Answer:

The potential difference between the plates is 8 V.

Explanation:

Given that,

Area of plates = 0.40 m²

Charge q=7.08\times10^{-10}\ C

Distance = 4.0 cm

We need to calculate the electric field

Using for formula of electric field

E=\dfrac{2q}{2\epsilon_{0}A}

Where, q = charge

A = area

Put the value into the formula

E=\dfrac{7.08\times10^{-10}}{8.85\times10^{-12}\times0.40}

E=200\ V/m

We need to calculate the potential difference between the plates

Using formula of potential difference

V=E\times d

Where, E = electric field

d = distance

Put the value into the formula

V=200\times0.04

V=8\ V

Hence, The potential difference between the plates is 8 V.

You walk 12 meters north, then 10 meters west. What is your displacement
Elodia [21]

Answer:

Your displacement is 15.62m NW

Explanation:

We can use the Phytagorean theorem to determine the displacement:

a^2+b^2=c^2

12^2+10^2=c^2

144+100=c^2

244=c^2

15.62=c

So your displacement is 15.62m NW

When did they start using the word "Scrubbed" for launches?
VladimirAG [237]

Answer:

Many speculation exists for why the term 'scrubbed' is used in relation to launches. <em>One of these is that during world war II, when the Air force planned bombing raids</em>. These  Air force missions had their briefings done with illustration of the details of the launch and and flight drawn on chalkboards. <em>When some of mission flight takeoffs were canceled (due to bad weather or a malfunction or other reasons) the details were then scrubbed off of the chalkboard</em>. This idea of the mission <em>being scrubbed meaning that it is no longer to be followed through with</em>, proceeded to this modern day rocket and aviation launches.

When using the spectroscope to view the spectra of the discharge lamps, what observations are recorded?.
natima [27]

When using the spectroscope to view the spectra of the discharge lamps, what observations are recorded by the wavelengths and colors of all bands.

<h3>Spectra of discharge lamps</h3>

The spectra of discharge lamp from spectroscope shows the different electromagnetic spectrum, they include the following;

  • Ultraviolet rays
  • Visible lights
  • Infra-red, etc

The electromagnetic spectrum consists of radiations of different wavelengths which are indicated by different color bands.

Thus, when using the spectroscope to view the spectra of the discharge lamps, what observations are recorded by the wavelengths and colors of all bands.

Guiana dolphins are one of the few mammals able to detect electric fields. In a test of sensitivity, a dolphin was exposed to th
iren [92.7K]

Answer:

0.05 V/m

Explanation:

V = Potential difference that is possible for the dolphin to detect = 0.5 mV

d = Distance between electrodes = 1 cm

Electric field strength is given by

E=\dfrac{V}{d}

\Rightarrow E=\dfrac{0.5\times 10^{-3}}{1\times 10^{-2}}

\Rightarrow E=0.05\ V/m

The corresponding electric field strength is 0.05 V/m
