Answer:
The answer is "Option B"
Explanation:
The PSU stands for "power supply unit", it is an internal component of a device which is used to convert current AC to DC power that is controlled by low-voltage, and other choices are not correct, that is explained as follows:
- In option A, HDD is used to store data, that's why it's wrong.
- In option C, It is a small memory chip, that is used to hold data.
- In option D, It is a device that is used to add a graphics card, that's why it is not correct.
Answer:
See the code below.
Explanation:
The nth armonic number is obtained from the following induction process:
![a_1 = 1](https://tex.z-dn.net/?f=a_1%20%3D%201)
![a_2 = 1+\frac{1}{2}=a_1 +1](https://tex.z-dn.net/?f=a_2%20%3D%201%2B%5Cfrac%7B1%7D%7B2%7D%3Da_1%20%2B1)
![a_3 = 1+\frac{1}{2}+\frac{1}{3}=a_2 +1](https://tex.z-dn.net/?f=a_3%20%3D%201%2B%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B1%7D%7B3%7D%3Da_2%20%2B1)
And for the the n term we have this:
![a_{n-1}=1+\frac{1}{2}+\frac{1}{3}+....+\frac{1}{n-1}](https://tex.z-dn.net/?f=a_%7Bn-1%7D%3D1%2B%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B1%7D%7B3%7D%2B....%2B%5Cfrac%7B1%7D%7Bn-1%7D)
![a_n = 1+\frac{1}{2}+\frac{1}{3}+......+\frac{1}{n}=a_{n-1}+\frac{1}{n}](https://tex.z-dn.net/?f=%20a_n%20%3D%201%2B%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B1%7D%7B3%7D%2B......%2B%5Cfrac%7B1%7D%7Bn%7D%3Da_%7Bn-1%7D%2B%5Cfrac%7B1%7D%7Bn%7D)
In order to create a code for the ne term we can use the following code using python:
# Code to find the nth armonic
# Function to find n-th Harmonic Number
def armonicseries(n) :
# a1 = 1
harmonic = 1
# We need to satisfy the following formulas:
# an = a1 + a2 + a3 ... +..... +an-1 + an-1 + 1/n
for i in range(2, n + 1) :
harmonic += 1 / i
return harmonic

And then with the following instructions we find the solution for any number n.
n = 3 # thats the number of n that we want to find
print(round(armonicseries(n),5))
