The objective of a microscope has a focal length

of 0.80 cm and the eyepiece has a focal length

of 4.0 cm. An object is placed 1.50 cm from the

objective. The final image is formed at the near

point of the eye (25 cm).

a) Calculate the distance of the image from the objective.

b) Calculate the distance from the eyepiece lens of the image in part a.

c) Calculate the angular magnification of the microscope.

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..
