I don’t know what it’s called but it’s where they can speak by moving there eyes
Answer:
A. simple to construct and easy to repair
Explanation:
A dynamic microphone works on the principle of electromagnetic principle. A diaphragm is attached to a coil of wire which helps in producing sound. Responding to the sound waves, the coil of the wire is vibrated by the diaphragm. A magnetic field is created by the magnet which is present inside the coil of wire. The electrical signal is generated in response to the motion of the coil. The speed of the motion produces the amount of the current.
Since the construction of a dynamic microphone is easier as compared to any other microphone, John is likely to opt to build one.
The code will have to obey the Pythagorean theorem that says square of the hypotenuse side is equals to the sum of the squares of the other legs.
<h3>How to write a code that check if a triangle is a right angle by using Pythagoras theorem?</h3>
The code is written in python.
def right_triangle(x, y, z):
if x**2 + y**2 == z**2 or y**2 + z**2 == x**2 or z**2 + x**2 == y**2:
print("it is a right angle triangle")
else:
print("it is not a right angle triangle")
right_triangle(6, 10, 8)
<h3>Code explanation</h3>
- we defined as function named "right_triangle". x, y and z are argument which are the length of the triangle.
- Then we check if the sides obeys Pythagoras theorem.
- If it does we print a positive statement else we print a negative statement.

3 radio buttons from the following code can be selected at any given time.
<u>Explanation:</u>
In any programming language end user prompts either checkbox or radio buttons.
Normally checkbox are used for end user to select true or false methods where return value will true if checkbox click or false, one or zero. It all depends how end user uses the checkbox in his or her programming languages.
Radio buttons are used to end user in the programming languages where to select one radio buttons out of given radio buttons.
Where each radio buttons are marked with own assigned values. Based upon user selecting the radio buttons return will be assigned value of selected radio button.
If select option is multiple, each category of radio button is placed in grouping.
