Answer:

Attenuation = 0.458\ db

Explanation:

Given

Power at point A = 100W

Power at point B = 90W

Required

Determine the attenuation in decibels

Attenuation is calculated using the following formula

Attenuation = 10Log_{10}\frac{P_s}{P_d}

Where P_s = Power\ Input and P_d  = Power\ output

P_s = 100W

P_d = 90W

Substitute these values in the given formula

Attenuation = 10Log_{10}\frac{P_s}{P_d}

Attenuation = 10Log_{10}\frac{100}{90}

Attenuation = 10 * 0.04575749056

Attenuation = 0.4575749056

Attenuation = 0.458\ db <em>(Approximated)</em>

This question is incomplete. The complete question is given below:

Write a program that asks the user to enter ten temperatures and then finds the sum. The input temperatures should allow for decimal values.

Sample Run

Enter Temperature: 27.6

Enter Temperature: 29.5

Enter Temperature: 35

Enter Temperature: 45.5

Enter Temperature: 54

Enter Temperature: 64.4

Enter Temperature: 69

Enter Temperature: 68

Enter Temperature: 61.3

Enter Temperature: 50

Sum = 504.3

Answer:

# Program in Python

sum = 0.0

for i in range(0, 10):

t = float( input("Enter the Temperature: "))

sum = sum + t

print("Sum: {0:0.1f}".format(sum))

Explanation:

  • Initialize the sum variable to hold the sum of input temperatures .
  • Iterate from 0 to 9, Get the input and compute the sum .
  • Print the result  by formatting the sum so that value is printed with precision to single decimal place .
