Why must the electric field be normal to the surface at every point of a charged conductor?
solong [7]
-- If the field were inclined to the surface, then it would have
some component parallel to the surface. 

-- Then, since we're talking about a conductor, the charges
on the object would move in response to that component
of the field, until there was no longer any component of the
field trying to move them.

What is the difference between air resistance and friction? ​
Vladimir [108]

Answer:Friction is a force that opposes the motion of objects; friction can cause objects to slow down. Air resistance is a type of friction. Air resistance causes moving objects to slow down. Different physical properties, such as the shape of an object, affect the air resistance on an object.

Which graph represents the solution set of the system of inequalities?<br><br> {−2x+y≤4y&gt;x+2
Jet001 [13]

Answer:

The fourth graph is the answer

Explanation:

We have inequalities

-2x+y\leq 4      \rightarrow y\leq 2x+4

y>x+2

For the first inequality all points at or below the graph of y are solutions, and for the second inequality all the points above the graph of y are the solutions. So, the solution to these inequalities are points that are above the graph of y>x+2 and below the graph of y\leq 2x+4. The shaded region in the fourth graph satisfies these conditions.

<em>Looking at other choices, we see that the first two graphs do not even represent the graphs of our inequalities, and the third graph does represent the inequalities but shades the wrong region. </em>

P.S: the graph of the inequality y>x+2  is dashed because   y is "greater than" and not "equal to" x+2, so this indicates that the values on the line y=x+2 are not included. And the graph of the inequality y\leq 2x+4 is a solid line because y is "less than or equal to" 2x+4, so we are including the values on the line y=2x+4, and that's why it's solid.
