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.

Lera25 [3.4K]

<h2>Solution :</h2>

The given problem is solved in Python.

def ComputeSquare():

side = float(input('Enter the side of the square: '))

if side > 0:

perimeter = 4 * side

area = side * side

print('Perimeter of the square is:',

perimeter, 'unit.')

print('Area of the square is:', area, 'square unit.')

print('Invalid input.')

ComputeSquare()

<h2>Explanation :-</h2>

In this program, we create a function ComputeSquare() to calculate the perimeter and area of a square.

The function asks the user to enter the side of the square. The side is then stored in a variable.

Now, we check whether the side is greater than 0 or not using if-else statement.

If the condition is true, the perimeter and area is calculated which is displayed using print() statement.

If the condition is false, the else blocks executes printing the error message.

Nonamiya [84]

Answer:

False.

Explanation:

A stethoscope is a medical instrument which is used for listening to the work of the heart and lungs. It consists of a microphone that rests on the patient's chest, and rubber tubes that bring the sound to the earphones. An ordinary stethoscope does not have any moving or electrical parts, as it only mechanically conducts sound from the patient's chest to the doctor's ear. One of the simplest examinations that doctors perform today is listening to the lungs and heart with a stethoscope. With the help of this instrument, noises are heard during the work of the lungs and heart.
