The figure shows an uncharged conducting cubic shell and a positive point charge Q outside the shell. There are two lettered poi

nts W and X inside the shell where the electric field can be measured. The electric field at points W and X are EW and EX, respectively. Point W is at the center of the cubic shell. Outside the shell are points Y and Z where the charge Q can be placed. All four points are along the same line. Which of the following statements is correct?
If the point charge is placed at point Y , EW>EX .


Answer A: If the point charge is placed at point Y , E sub W is greater than E sub X .


Answer B: If the point charge is placed at point Y , E sub W is less than E sub X .


Answer C: If the point charge is placed at point Z , E sub W is greater than E sub X .


Answer D: If the point charge is placed at point Z , E sub W is less than E sub X .


Answer E: If the point charge is placed at point Z , E sub W is equal to E sub X .

If the point charge is placed at point E_W is equal to E_X.

<h3>Electric field inside a conducting cubic shell</h3>

The electric field inside a conducting cubic shell is zero. When a point charge is placed outside the shell, the electric field outside the shell is greater than the electric field inside the shell which is zero.

We can deduce the following;

  • Electric field inside the shell is zero, thus E_W = E_X =0
  • Electric field outside the shell is greater than electric field inside the shell

Thus, the only correct statement is, If the point charge is placed at point E_W is equal to E_X.

You observe a spiral galaxy with a large central bulge and tightly wrapped arms. It would be classified a
miv72 [106K]

Answer:

Sa

Explanation:

Spiral Galaxies  -

It is a disk shaped galaxies which have spiral structure , is refereed to as spiral galaxies .

According to Hubble , these galaxies are classified as Sa , Sb , Sc .

Where ,

Sa - have the structure , which is bulged from the central portion , along with a tightly wrapped spiral structure .

Sb - have a lesser bulge and the spiral is looser .

Sc - It has very weak bulge with the open spiral structure .

Hence , from the question ,

The given information is about the Sa .

Which does not represent a change in velocity?
alina1380 [7]

Answer:

A balloon is floating up into the air at 1 m/s.

Explanation:

Velocity is the displacement divided by the time;

   Velocity = \frac{displacement}{time}

It is a vector quantity that has magnitude and direction.

The choice that shows a change in direction is a correct specification of velocity.

A balloon floating up into the air at 1m/s shows no directional change.
