<em>The direction the electric field points at a position directly west of a positive charge is;</em>
B. South
<u>Field lines always point away from the positive end of a magnet. </u>
<u>Thus, if you are South of a magnet, the field lines will point south.</u>
For questions like this there are only a couple of possible equations you need to look at :)
In this case the equation for Kinetic energy (energy of motion) is:
Simply plug in the mass and velocity variable given in the question and you have your answer :)
Answer:
A) q = -8.488 cm
, B) m = 0.29
Explanation:
A) For this exercise in geometric optics, we will use the equation of the constructor
where p and q are the distance to the object and image, respectively and f is the focal length
in our case the distance the object is p = 29 cm the focal length of a diverging lens is negative and indicates that it is f = - 12 cm
we calculate
= - 0.1178
q = -8.488 cm
the negative sign indicates that the image is virtual
B) the magnification is given
we substitute
m =
m = 0.29
the positive sign indicates that the image is right
Answer:
Explanation:
As warm air comes in contact with the glass, the air becomes cooler. When that happens the cool air can't hold as much water vapor which condenses on the glass.
The answer is C.
