Answer:
d) The image would be dimmer
Explanation:
When inverted image of an object is viewed on a screen from the side facing a converging lens, the
lens focuses the diverging, and blurred light rays from the distance object through refraction of the rays two times.Then the rays is converge by the double bending cl at a focal point behind the lens inorder for a sharper image to be be observed.
But when an opaque card is then introduced to cover only the upper half of the lens then the image becomes dimmer because of the reduction in the light intensity on the screen by 50%
Honestly you should switch it up to something better cause honestly all depends on how the person was raised or the backround of them
it does not matter if your are a male or female
The choices can be found elsewhere and as follows:
A)There will not be a change.
<span>B)The voltage will decrease by a factor of two. </span>
<span>C)The voltage will increase by a factor of two. </span>
<span>D)The two coils of wire will cancel out the magnetic field. </span>
<span>E)The voltage will be zero.
</span>
I believe the answer is option C. If the magnet is put inside two coils of wire, then the voltage will increase by a factor of two. Hope this answers the question.
Answer:
It will emerge at its initial speed not a slower speed.
Explanation:
It will emerge at the initial speed because the medium at the point of emergence is the same as the medium before incidence.
Light moves at a constant speed in any particular medium. Hence, the speed of light in air is constant in air and the speed of light in glass is constant in glass.
Yes its bigger than 5 millimeters
