Answer:
d = 79 m
, d = -43 m
Explanation:
This in an exercise of movement in one dimension, the displacement is a vector and the distance is the scalar
Let's calculate the distance
d = 35 + 18 +26
d = 79 m
Displacement which is a vector
d = -35 +18 - 26
d = -43 m
thebold indicate vector. The negative sign indicates that the movement is to the left
Explanation:
(i)
O is the object and I is the image.
The image formed is enlarged and it is erect. So the magnification will be positive (+) and greater than 1.
Refer above image. 1
(ii)
O is the object and I is the image.
The image formed is diminished and erect. So the magnification will be positive (+) and less than1.
Refer above image. 2
(iii)
The image will be formed as the 2F on the other side of the lens and it will be of same of the object.
It expands, increasing in volume. The warmer the water, the more space it takes up, and the lower its density.
