Answer:
Is all about people – how many of us there are, how we shape the world around us, and how we interact with each other.
Explanation:
1. Height of the object is 5 cm
The object distance (u) is 18 cm
The focal length is 10 cm
To calculate the image distance (v) we use;
1/f=1/v+1/u
1/v = 1/10-1/18
= 8/180
Therefore v = 180/8
= 22.5 cm
2. Height of the image
Magnification = v/u = Height of image/height of object
Therefore;
22.5/ 18= x/5
x = (22.5×5)/18
x = 6.25 cm
Therefore; the height of the image is 6.25 cm
Answer:
Consinder the first body
Consider the second body
The body of mass 4 kg had the greater potential energy than the body of 2 kg
let's find the coordinates of the points on the line.
(-1, -2)(1, 3)
