Suppose the work required to stretch a spring from 1.1m beyond its natural length to a meters beyond its natural length is 5 J,

Nadya [2.5K]

Answer:

Explanation:

The formula for the work done on a spring is:

$W = \frac{1}{2}kx^{2}$

where k is the spring constant and x is the change in length of the string

For the first statement,

x = (a-1.1), W = 5

=> $5 = \frac{1}{2}k(a-1.1)^{2}$

Now making k the subject of formula, we have:

$k = \frac{10}{(a-1.1)^2} ---------------- (A)$

For the second statement,

x = (a-4.8), W = 9

=> $9 = \frac{1}{2}k(a-4.8)^{2}$

Now making k the subject of formula, we have:

$k = \frac{18}{(a-4.8)^{2} } ------------------------- (B)$

Equating A and B since k is constant, we have:

$\frac{10}{(a-1.1)^{2} } = \frac{18}{(a-4.8)^{2} }$

solving for the value of a

$8a^{2} +56.4a-208.62=0$

solving for a, we get:

a = 2.6801 or -9.7301

but since length cannot be negative, a = 2.68m

substituting the value of a in equation B, we have:

$k=\frac{18}{(2.68-4.8)^{2} }$

k = 4.005

Write a program that removes all non-alpha characters from the given input. Ex: If the input is: -Hello, 1 world$! the output is

Nuetrik [128]

Answer:

Explanation:

The following code is written in Python. It is a function that takes in a string as a parameter, loops through the string and checks if each character is an alpha char. If it is, then it adds it to an output variable and when it is done looping it prints the output variable. A test case has been provided and the output can be seen in the attached image below.

def checkLetters(str):

output = ''

for char in str:

if char.isalpha() == True:

output += char

return output
