What Occurs when all forces acting on an object cancel out, and there is no movement

1 answer:

8 0

When all forces acting on an object cancel out, and there is no movement, the force is called A. balanced force. A balanced force for example is a vase in the inclined plane stopped by a box. The force exerted by the box to the vase is equal to the sine of the weight of the base where the two cancels out.

Create the logic for a game that simulates rolling two dice by generating two random numbers between 1 and 6 inclusive. The play

guajiro [1.7K]

Answer:

The solution code is written in Python 3.

import random
count = 0
flag = False
guess = int(input("Input your guess (2-12): "))
while(count <=3):
dice1 = random.randint(1, 7)
dice2 = random.randint(1, 7)
if((dice1 + dice2) == guess):
flag = True
count += 1
if(flag):
print("User wins!")
else:
print("Computer wins!")

Explanation:

A Random generator is needed for this question and therefore we start by importing Python random class (Line 1)

Next, create one counter variable, count, to ensure there will be only three rolling of the dices (Line 3). We need another variable, flag, to track the status if the two dices equal to the guess number chosen by user (Line 4).

Next, prompt use to input a guess number (Line 5).

Within the while loop, we can use random class method randint() to generate random integer. The arguments 1 and 7 will give one random number ranged from 1 to 6 for dice1 and dice2, respectively (Line 8 - 9).

If the total of dice1 + dice2 equal to user guess, we turn the flag to True. If not, the flag will remain False after completing entire while loop.

If the flag turned to True, print the message "User Wins!" else print the message ("Computer wins!")

1. Write a program to prompt the user to enter a single character and respond back whether or not the character is valid dna. 2.

Nina [5.8K]

Answer:

Answer 1:

dna = input("Enter DNA type: ")

dna = dna.upper()

print(dna)

if dna == "A" or dna == "B" or dna == "Z":

print("valid")

else:

print("invalid")

Answer 2:

rna = input("Enter DNA type: ")

rna = rna.lower()

print(rna)

if rna == "m" or rna == "t" or rna == "r":

print("valid")

else:

print("invalid")

Answer 3:

dnaSquence = input("Enter the DNA sequence: ")

type = "valid"

for char in dnaSquence:

if char not in ["A", "C", "G", "T"]:

type = "invalid"

break

print(type)

Answer 4:

rnaSquence = input("Enter the RNA sequence: ")

type = "valid"

for char in rnaSquence:

if char not in ["A", "C", "G", "U"]:

type = "invalid"

break

print("valid")

Explanation:

There are three types of DNA; Type A, Type B and Type Z.

A DNA sequence consists of; A, C, G and T.

There are three types of RNA; mRNA, tRNA and rRNA.

An RNA sequence consists of; A, C, G and U.

Code Explanations:

Code 1:

dna = input("Enter DNA type: ")

dna = dna.upper()

print(dna)

if dna == "A" or dna == "B" or dna == "Z":

print("valid")

else:

print("invalid")

prompts and Takes a single character input
converts the character to upper case
compares the input to the DNA types
Prints "valid" for a valid input else prints "invalid"

Code 2:

rna = input("Enter DNA type: ")

rna = rna.lower()

print(rna)

if rna == "m" or rna == "t" or rna == "r":

print("valid")

else:

print("invalid")

prompts and Takes a single character input
converts the character to lower case
compares the input to the RNA types
Prints "valid" for a valid input else prints "invalid"

Code 3:

Answer 3:

dnaSquence = input("Enter the DNA sequence: ")

type = "valid"

for char in dnaSquence:

if char not in ["A", "C", "G", "T"]:

type = "invalid"

break

print(type)

It prompts for a DNA sequence.
Declares a string variable "type" and initializes type to valid.
The FOR loop checks every character in the DNA sequence.
If the character is not in the list [A, C, G, T] type becomes invalid and the loop breaks and the type "invalid" is printed to the screen.
if all the characters are in the list, then type will remain valid and will be printed to the screen.

Code 4:

rnaSquence = input("Enter the RNA sequence: ")

type = "valid"

for char in rnaSquence:

if char not in ["A", "C", "G", "U"]:

type = "invalid"

break

print("valid")

It prompts for a RNA sequence.
Declares a string variable "type" and initializes type to valid.
The FOR loop checks every character in the RNA sequence.
If the character is not in the list [A, C, G, U] type becomes invalid and the loop breaks and the type "invalid" is printed to the screen.
if all the characters are in the list, then type will remain valid and will be printed to the screen.

If an organization’s DNS server can resolve a DNS request from its own cache, the DNS server is said to be ____.

abruzzese [7]

Answer:

Answered below

Explanation:

The DNS server is said to be a caching-only DNS server.

A caching-only Domain Name System server, works by recieving queries from the client, proceeds to perform queries against other named servers, then caches the results and returns the results to the client.

Subsequent queries are resolved and returned for the specified host straight from the the cache, by the server, instead of submitting to the external server.

The advantage of this process is that it reduces traffic from outgoing DNS and speeds up the name resolution. Also, there is a reduction in the amount of query traffic.
