An object with a height of 0.3 meter is placed at a distance of 0.4 meter from a concave spherical mirror. an image with a height of 0.1 meter is formed in front of the mirror. how far from the mirror is the image located?

We can use the magnification equation for this problem.

Magnification equation:

hi/h0 = di/d0

Where in hi : image size, h0 : object size, di : image distance, d0 : object distance from mirror

So plugging in the given variables we will have the corresponding equation

0.1 m / 0.3 m = di / 0.4 m

di = 0.1333333m

The generated image of the object is located 0.13 meters or 13 cm away from the mirror

the correct answer is a

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
