Find the electric flux through a cylindrical Guassian surface produced by a point charge at base.

Physics

Simora [160]3 years ago
7 0

Answer:

Electric flux will be \Phi =\frac{q}{\epsilon _0}

Explanation:

Let the point charge enclosed by Gaussian surface is q

We have to find the electric flux through this Gaussian surface

According to Gauss law electric flux through any closed surface is equal to \frac{1}{\epsilon _0} times of charged enclosed by the surface.

So electric flux will be \Phi =\frac{q}{\epsilon _0}

Gauss law is only valid for closed surface it is not applied for open surface

Which statement about thin lenses is correct? In each case, we are considering only a single lens. A. A diverging lens always pr
Alexus [3.1K]

Answer:

E) true. The image is always virtual and erect

Explanation:

In this exercise we are asked to find the correct statements,

for this we can use the constructor equation

     1 / f = 1 / p + 1 / q

where f is the focal length, p the distance to the object and q the distance to the image

In diverging lenses, the focal length is negative and the image is virtual and erect

In convergent lenses, the positive focal length, if the object is farther than the focal length, the image is real and inverted, and if the object is at a shorter distance than the focal length, the image is virtual and straight.

With this analysis let's review each statement

A) False. The image is right

B) False. The type of image depends on where the object is with respect to the focal length

C) False. The real image is always inverted

D) False. The image is always virtual

E) true. The image is always virtual and erect

A 3kg chunk of putty moving at a speed of 5 m/a collides with, and sticks to, a 5kg. bowling ball that is initially at REST. The
astraxan [27]
You'd have an easier time using the equation if you understood where the equation comes from.

The law here ... the major principle to remember, the key, the fundamental truth, the big cookie ... is the fact that momentum is conserved.  <em>The total momentum after they join up is the same as the total momentum before they meet.</em>

Momentum of an object is (mass) times (speed).

Now, list all the things you know, before and after the putty meets the ball:

<u>Before:</u><u>  </u>There are two objects.
Mass of putty = 3 kg
Speed of putty =  5m/s
Momentum of putty = 3 x 5 = 15 kg-m/s.

Mass of ball = 5 kg
Speed of ball = zero
Momentum of ball = 5 x 0  =  zero

Total momentum of both things = 15 kg-m/s


<u>After</u>:  There is only one object, because they stuck together.
Mass of (putty+ball) = (3+5) = 8 kg
Speed of (putty+ball) = we don't know; that's what we have to find

Momentum of (putty+ball) = 8 x (speed)

===================================

We know that the momentum after is equal to the momentum before.

8 x (speed) = 15 kg-m/s

Divide each side by  8 :

Speed = 15 / 8  =  <em>1.875 m/s </em>  after they stick together.
