Writing a function that implements a loop to collect a set amount of data. The function should use the serial object, the record

ing time, and the iteration (city number) as input arguments and return an N x 2 array with the time in the first column and the recorded light level in the second. (4 pts). Include in this function outputs to the Command Window noting the starting and stopping of the recording.

3.A ball is thrown into the air with an initial velocity of 15 m/s. a.How long does it take the ball to reach maximum height?b.W
ehidna [41]

Answer:  a) = 1.5 sec.  b= 11.5 m. c=0  d= 1.5 sec.

Explanation:

a) Once thrown into the air , the only influence on the ball is gravity, so, we can conclude that the acceleration acting on the ball is the one due to gravity, i.e., g= 9.8 m/sec².

Applying the definition of acceleration, we can write the following equation:

a= (vf-vo) / t   ⇒ g = vf-vo / t. (1)

Now, when the ball reaches to his maximum height, it stops momentarily, and then starts to fall, so for this height, we can write vf=0.

Replacing  in (1), and solving for t, we get:

t = (0 -vo) / g = -15 m/s/ - 9.8 m/sec² (Taking upward as positive  direction)

a) t= 1.5 sec.

Replacing this value in the kinematic equation for displacement, when vo=15 m/s, we get:

hmax: 15 m/sec . 1.5 sec -1/2. 9.8 m/sec². (1.5 sec) ² (2)

b) hmax= 11.5 m

c) vf= 0 (as explained above)

Finally, in order to know how long the ball takes to return to its initial height, we know that for the falling part of the trajectory, vo=0, so we can write the equation for displacement as follows:

h=-hmax (because it returns to the same starting point)= 1/2 gt²=-11.5 m

Solving for t, we get:

d) t=1.5 sec.

It can be seen that the time used in going up, it is the same for going down, to travel the same distance.

This result is completely general and applies to any free fall problem.

1What kind of rules protect everyone’s rights when we use each other’s content
Tanya [424]

Answer:

1. Copyright.

2. Songs and books.

Explanation:

A copyright law can be defined as a set of formal rules granted by a government to protect an intellectual property by giving the owner an exclusive right to use while preventing any unauthorized access, use or duplication by others.

For example, when an individual downloads a song owned by any record company without paying a purchase fee, it is a violation of copyright law.

A copyright can be defined as an exclusive legal right granted to the owner of a creative work (intellectual property) to perform, print, record, and publish his or her work. Also, the owner is granted the sole right to authorize any other person to use the creative work.

Hence, copyright is a kind of rules that protect everyone’s rights when we use each other’s content.

An intellectual property can be defined as an intangible creation of the human mind, ideas, thoughts or intelligence. Some examples of an intellectual property are songs, books, poems, technology, design etc.

What is the reason that a modern electron microscope (TEM) can resolve biological images to the subnanometer level, as opposed t
zhannawk [14.2K]

Answer:

The correct answer to the following question will be "The wavelengths of the electron beams are also much shorter or less than illumination and visible light".

Explanation:

TEM seems to be a methodology of microscopy during which a pulse of electrons is transferred to create the effect through some kind of microscope, could approach biological objects at the sub-nanometer standard, as related to hundreds of nano-meters for either the absolute best microscope with super-resolution.

Also because of the electron beam's distances, they are still much shorter or smaller than daylight and infrared light, meaning that biological objects and artifacts can be resolved.

CS160 Computer Science I In class Lab 10
lianna [129]

Answer:

The program in Python is as follows:

fname = input("Enter the translation file name: ")

with open(fname) as file_in:

   lines = []

   for line in file_in:

       lines.append(line.rstrip('\n'))

myDict = {}

for i in range(len(lines)):

x = lines[i].split(":")

myDict[x[0].lower()] = x[1].lower()

print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")

word = input("Enter an English word: ")

while(True):

if not word:

 break

if word.lower() in myDict:

 print("The Spanish word is ",myDict[word.lower()])

else:  

 print("I don’t have that word in my list.")

word = input("Enter an English word: ")

Explanation:

This prompts the user for file name

fname = input("Enter the translation file name: ")

This opens the file for read operation

with open(fname) as file_in:

This creates an empty list

   lines = []

This reads through the lines of the file

   for line in file_in:

This appends each line as an element of the list

       lines.append(line.rstrip('\n'))

This creates an empty dictionaty

myDict = {}

This iterates through the list

for i in range(len(lines)):

This splits each list element by :

x = lines[i].split(":")

This populates the dictionary with the list elements

myDict[x[0].lower()] = x[1].lower()

This prints an instruction on how to use the program

print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")

This prompts the user for an English word

word = input("Enter an English word: ")

This loop is repeated until the user presses the ENTER key

while(True):

If user presses the ENTER key

if not word:

The loop is exited

 break

If otherwise, this checks if the word exists in the dictionary

if word.lower() in myDict:

If yes, this prints the Spanish translation

 print("The Spanish word is ",myDict[word.lower()])

If otherwise,

else:

Print word does not exist

 print("I don’t have that word in my list.")

Prompt the user for another word

word = input("Enter an English word: ")
