A capacitor is charged to 8.0×10−4 C , then discharged by connecting a wire between the two plates. 35us after the discharge beg

Anettt [7]

Answer:

The average current is 19.567 A

Solution:

As per the question:

Charge, Q = $8.0\times 10^{- 4}\ C$

Time, t = $35\times 10^{- 6}\ s$

Now,

We know that current is constituted by the rate of transfer of the charge per unit time. Thus we can write:

I = $\frac{Q}{t}$ (1)

Now, the charge that was transferred is 86 % of the original value.

Therefore,

We replace Q by 0.86Q in eqn (1):

I = $\frac{0.86\times 8.0\times 10^{- 4}}{35\times 10^{- 6}} = 19.657\ A$

What is Index of refraction?

Sphinxa [80]

Refractive Index is the measure of bending of light rays.

Explanation:

Index of refraction or Refractive Index is the measurement of the phenomenon exhibited by light rays - bending of light rays when passing from one medium to another.
It can also be measured as the ratio between speed of light in vacuum or empty space to that of the speed of light in a given medium.
Index of refraction is denoted by n and is calculated by the following formula

n = Speed of light in vacuum/Speed of light in the given medium = c/v

It can also be measured using the angle of incidence and angle of refraction.

n = sin i/sin r where i is the angle of incidence and r is the angle of refraction

OlgaM077 [116]

The given question is incomplete. The complete question is as follows.

Two identical balls each have a mass of 35.0 grams and a charge of q = 3.50 \times 10^{-6}C[/tex]. The balls are released from rest when they are separated by a distance of 6.00 cm. What is the speed of each ball when the distance between them has tripled? Use k = $9.00 \times 10^{9} Nm^{2}/C^{2}$ .
