Twisted copper telephone wire, coaxial copper cable, fiber-optical cable, and media for wireless transmission are all physical transmission medium.
A system or material that can mediate the propagation of signals for telecommunications purposes is referred to as a transmission medium. Typically, signals are applied to a wave of some sort that is appropriate for the selected medium.
For instance, data may modulate sound, and while air is a common transmission channel for sounds, solids and liquids can also be used. A useful transmission medium for electromagnetic waves like light and radio waves is vacuum or air.
Although a physical substance is not necessary for the propagation of electromagnetic waves, these waves are typically impacted by the transmission medium they pass through, for example, by absorption, reflection, or refraction at the interfaces between media. Therefore, waves can be transmitted or guided using technical devices.

Answer:
Required code is given below:
Explanation:
def add_to_dict(dictt, key,value):
if key in dictt.keys():
print("Error. Key already exists.")
else:
dictt[key]=value
return dictt
def remove_from_dict(dictt,key):
try:
dictt[key]
dictt.pop(key, None)
return dictt
except KeyError:
print("No such key exists in the dictionary.")
def find_key(dictt,key):
try:
value=dictt[key]
print("Value: ", value)
except KeyError:
print("Key not found.")
It would be margins. none of the others are even terms for anything.
Explanation:
I have attached the answer as an image. I can't upload the file as it requires a licensed product and I only used demo version. I can provide the file too if you can give me your vlsig file required to use full software. However, If you just copy along the images on your Visual Studio, you will easily create the files yourself. Answer is provided for both scenarios as part A and part B, one which stops after 1 iteration and the one which loops until 0 height is given.
Answer:
sendObject(John_Doe);
Explanation:
The above code has been written in Java.
Since the calling class is the same that declares it, to invoke the method, simply call its name with its argument(s) in a pair parentheses. The name of the method is "sendObject" and its argument is a reference to an object of type Customer saved in a variable called "John_Doe". This can be written as follows:
sendObject(John_Doe);
Hope this helps!
