Convex lenses when placed in the air, will cause rays of light (parallel to the central axis) to converge.
Converging lenses, commonly referred to as convex lenses, have thicker centers and narrower upper and lower margins. The edges are outwardly curled. This lens has the ability to concentrate a beam of parallel light rays coming from the outside onto a spot on the opposite side of the lens.
The image created is referred to be a genuine image when it is inverted relative to the object. On a screen, this kind of image can be recorded. When the object is positioned at a point farther than one focal length from the lens, a converging lens creates a true image.
A virtual image is one that cannot be produced on a screen and is formed when the image is upright in relation to the object. When an item is positioned within one focal length of a converging lens, a virtual image is created. It creates an enlarged image of the object on the same side of the lens as the image. It serves as a magnifier.

The speed with which Jennifer climb up the tree is 0.45 m/s
The distance is 10m
Time is 22 seconds
Required speed is 10/22=0.45 m/s
- Distance is the total length travelled by an object.
- Speed is distance upon time.
- It is a scalar quantity and doesn't has magnitude and direction.
- Distance traveled is the total length of the path traveled between two positions
- Distance is the total movement of an object without any regard to direction.
- Distance is the total movement of an object without any regard to direction.

b) by the end of the fifth day, group b will be more than one cm taller than group a. eliminate
Explanation:
The correct prediction based on the data shown is that by the end of the fifth day, group B plants will be more than 1cm taller than group A plants.
let us examine the table closely;
Day Group A (Water Only) Plant Height (cm) Group B (Water and Fertilizer)
1 2.0 2.0
2 2.2 2.3
3 2.3 2.8
4 2.5 3.2
5 2.6 3.8
We can see that by the end of the fifth day, the height differences between the two plants, 3.8 - 2.6 = 1.2cm, this is greater than 1cm. This claim from the experiment is very correct.
Other predictions are false.
