What technical was the microscope invented in?
Ilia_Sergeevich [38]

Answer:

Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope in 1590.

Explanation:

A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses. Eeuwenhoek observed animal and plant tissue, human sperm and blood cells, minerals, fossils, and many other things that had never been seen before on a microscopic scale. He presented his findings to the Royal Society in London, where Robert Hooke was also making remarkable discoveries with a microscope.

<h3>The kinds of data type.</h3>

In Computer programming, there are five recognized data types and these include:

  • Integer type (int).
  • Character type (char).
  • Floating point type (float).
  • Boolean (bool)
  • String (str)

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

A string is a data type which is typically used for data values that comprises ordered sequences of characters.

In Java programming, strings can be used to represent all Java data types such as numbers, Boolean, strings, etc. Also, the <u>%s</u> format specifier can be used by a programmer or software developer to receive any type of Java data.

Write the program to solve quadratic equations, but if the discriminant is negative, output
Firdavs [7]

Answer:

PROGRAM  QuadraticEquation Solver

  IMPLICIT  NONE

REAL :: a, b, c ;

  REA :: d ;

  REAL  :: root1, root2 ;

//read in the coefficients a, b and c

  READ(*,*)    a, b, c  

  WRITE(*,*)   'a = ', a

  WRITE(*,*)   'b = ', b

  WRITE(*,*)    'c = ', c

  WRITE(*,*)

// computing the square root of discriminant d

  d = b*b - 4.0*a*c

  IF (d >= 0.0) THEN              //checking if it is solvable?

     d     = SQRT(d)

     root1 = (-b + d)/(2.0*a)     // first root

     root2 = (-b - d)/(2.0*a)     // second root

     WRITE(*,*)  'Roots are ', root1, ' and ', root2

  ELSE                            //complex roots

     WRITE(*,*)  'There is no real roots!'

     WRITE(*,*)  'Discriminant = ', d

  END IF
