A parallel plate capacitor has circular plates with diameter D=21.5 cm separated by a distance d=1.75 mm. When a potential diffe

OLga [1]

Answer: $E=2.078\times 10^{-10} J/cm^3$

Explanation:

Given

Diameter(D)=21.5 cm

distance between plate=1.75 mm

and we know capacitance is

$C=\frac{\epsilon _0A}{d}$

and we know charge is

Q=CV

and charge density ( $\sigma [tex])[tex]=\frac{Q}{A}=\frac{\epsilon _0AV}{Ad}=\frac{\epsilon V}{d}$

Electric field(E) $=\frac{\sigma }{\epsilon _0}$

Energy density $=\frac{1}{2}\epsilon _0E^2$

Energy desity $=\frac{4\pi \epsilon _0}{8\pi }\frac{V^2}{d^2}$

Energy desity $=\frac{1}{8\pi \cdot 9\times 10^9}\times \left [ \frac{12\times 10^3}{1.75}\right ]^2$

$E=2.078\times 10^{-10} J/cm^3$

488 J of work is done to a box which is moved across the floor for a distance of 8.9 m. What net force is required to act on the

kvv77 [185]

According to the formula
$a = f \times d$
Where a is work, f is force and d is the distance that box was moved over. And from that formula, you can get that f = a/d and that is 54.83N of force

Nataliya [291]

The sun’s huge mass gives it a strong gravitational pull. Because of this gravitational pull, planets that are closer to the sun tend to have different motion than planets that are further away from the sun, because the gravity becomes stronger the closer you get. I hope this helped!

lutik1710 [3]

Answer:

176ft/s

Explanation:

Speed of a wave is a function of the frequency and wavelength of the wave. It is expressed mathematically as:

V = fλ where:

V is the speed of the wave

f is the frequency

λ is the wavelength

Given f = 16Hz, λ = 11ft

V = 16×11

V = 176ft/s
