What is the magnification of an astronomical telescope whose objective lens has a focal length of 71 cm and whose eyepiece has a
Rus_ich [418]

To solve this problem it is necessary to apply the concepts related to optical magnification (is the process of enlarging the apparent size, not physical size, of something.). Specifically the angular magnification of an optical telescope is given by

M = -\frac{f_o}{f_e}

Where,

f_o = Focal length of the objective lens in a refractor

f_e = Focal length of the eyepiece

Our values are given as

f_o = 71cm

f_e =  2.1cm

Replacing we have

M = -\frac{f_o}{f_e}

M = -\frac{71}{2.1}

M = - 33.81

Therefore the magnification of this astronomical telescope is -33.81

A2 = 16 m^2

Explanation:

Application of Pascal's law:

F1/A1 = F2/A2

Given:

F1 = 50 N. A1 = 1 m^2

F2 = 800 N A2 = ?

A2 = (F2/F1)A1 = (800 N/50 N)(1 m^2)

= 16 m^2

<h3>What is a watermark?</h3>

A watermark is a faint design made in paper during manufacture that is visible when held against the light and clearly identifies the maker.

The watermark can be of different types depending on the application and they include:

  • A robust watermark will not resist tampering.
  • A fragile watermark will resist manipulations of the media.

Thus, The first blank is robust watermark; a robust watermark will not resist tampering.

The second blank is fragile watermark; a fragile watermark will resist manipulations of the media.
