Answer:
As the object moves parallel to principle axis the image of the object will continuously moves away from the principal axis so the horizontal distance will increase
Explanation:
As the object is moving towards the lens then in that case first the image will form between the focus and double the distance of focus.
So here the image is diminished
now when the object is at large distance from from lens then its image will form at focus and it is of very small size
Now as the object comes closer to the lens till the object distance is 2F the image size will increase but smaller then object size
Now when object is between F and 2F then the image size will be more than object size and it will increase to infinite magnification
So overall we can say that as the object moves parallel to principle axis the image of the object will continuously moves away from the principal axis so the horizontal distance will increase
Answer:
your answer for this question is B
Answer:4.7N
Explanation:both of the sides are equal
The amount of heat needed to increase the temperature of a substance by
is given by
where
m is the mass of the substance
is its specific heat capacity
is the increase of temperature
The sample of silver of our problem has a mass of
. Its specific heat capacity is
and the increase in temperature is
Therefore, the amount of heat needed is
