An object of 8 cm height is 15 cm in front of a converging lens with focal length of magnitude 4 cm. what is the dimension of the image? do not include the sign)?

image height is 2.9 cm

Explanation:

We have given the size of the object O = 8 cm

Distance of the object from the lens = 15 cm

Focal length of the lens = 4 cm

Now for lens we know that

So

v = 5.454 cm

Now magnification

Now magnification is the ratio of image height and object height

So , where I is the height of image and O is the height of object

So

I =2.9 cm

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

yup its correct its: c) b b
