Answer: When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. There is no change in either the magnitude or direction of its velocity. That is, there is zero acceleration.
Answer:
Image distance = 44.8cm, Image height = 16.5cm, Magnification = 0.42
The image is a virtual and upright image.
Explanation:
The nature of image formed by an object placed in front of a convex mirror is always diminished, virtual and erect.
The focal length f and the image distance are always NEGATIVE beacause the image is formed behind the mirror.
Given f = -33.0cm, v = -19.0cm
using thr mirror formula to get the object distance u, we have;
![\frac{1}{f}=\frac{1}{u} + \frac{1}{v}\\ \frac{1}{u}=\frac{1}{f} - \frac{1}{v}\\\frac{1}{u}=\frac{1}{-33} - \frac{1}{-19}\\\frac{1}{u}=\frac{-19+33}{627} \\\frac{1}{u}=\frac{14}{627} \\u=\frac{627}{14} \\u = 44.8cm](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bf%7D%3D%5Cfrac%7B1%7D%7Bu%7D%20%2B%20%5Cfrac%7B1%7D%7Bv%7D%5C%5C%20%5Cfrac%7B1%7D%7Bu%7D%3D%5Cfrac%7B1%7D%7Bf%7D%20-%20%5Cfrac%7B1%7D%7Bv%7D%5C%5C%5Cfrac%7B1%7D%7Bu%7D%3D%5Cfrac%7B1%7D%7B-33%7D%20-%20%5Cfrac%7B1%7D%7B-19%7D%5C%5C%5Cfrac%7B1%7D%7Bu%7D%3D%5Cfrac%7B-19%2B33%7D%7B627%7D%20%5C%5C%5Cfrac%7B1%7D%7Bu%7D%3D%5Cfrac%7B14%7D%7B627%7D%20%5C%5Cu%3D%5Cfrac%7B627%7D%7B14%7D%20%5C%5Cu%20%3D%2044.8cm)
To calculate the image height, we will use the magnification formula
M = ![\frac{image\ height}{object\ height}=\frac{image\ distance}{object\ distance} \\](https://tex.z-dn.net/?f=%5Cfrac%7Bimage%5C%20height%7D%7Bobject%5C%20height%7D%3D%5Cfrac%7Bimage%5C%20distance%7D%7Bobject%5C%20distance%7D%20%20%5C%5C)
M = ![\frac{Hi}{HI}=\frac{v}{u}](https://tex.z-dn.net/?f=%5Cfrac%7BHi%7D%7BHI%7D%3D%5Cfrac%7Bv%7D%7Bu%7D)
Given Hi = 7.0cm
v = 19.0cm
u = 44.8cm
HI = 7*44.8/19
HI = 16.5cm
The object height is 16.5cm
Magnification = v/u = 19.0/44.8 = 0.42
SInce the image is formed behind the mirror, the image is a VIRTUAL and UPRIGHT image
well that be 1 and 2/3
to check just add 1 and 2/3 + 3 and 1/3 and get 5
