Answer: A. at the point which
is twice the focal lenght of the lens of the camera
Explanation:
When a certain document is to be produced through the use of a duplicating camera, it should be noted that the camera should be placed at the point which is twice the focal lenght of the lens of the camera so as to get the exact copy of the document.
It should be noted that placing the camera between the principal and a point twice the focal lens of the camera lens or beyond a point that's twice the focal length will not produce the document.
Therefore, the correct option is A
<span>Discuss the relationship between electric and magnetic fields. How are they related?</span>
The magnetic field is related to the electric field in such a way that magnetic fields moves perpendicular the electric field. This relationship exists between a magnetic field and an electric field is a consequence of associating elementary particles.

Answer:
it opens the circuit so that electric charges do not flow to the timier
Explanation: a closed circut will allow electrisity to flow through.
<span>circumference of orbit = pi*1/2*1.5e11m = 2.356e11 meters
in 13 weeks, there are 13*7*24*60*60 seconds = 7.862e6 seconds
avg speed = 1/4*2.356e11meters/7.862e6sec = 0.07492e5 = 7.49e3m/sec
the avg velocity is 1.414* radius of the orbit </span>
so just plug in the velocity for v, which is 20 m/s
and plug in the time for seconds which is 3.5s
so
that will give you your answer
