Answer:
Reflection
Explanation:
Reflection is the property of light in which when a ray of light hits a smooth surface, it bounces back in the direction in which it came from. If i is the angle between the normal to the surface and the incident ray, and r is the angle between the normal and reflected ray, the law of reflection states that the angle of incidence equals the angle of reflection. That is, i = r.
So, to record the image of an object with a camera, one property of light that makes that possible is reflection because, the incidence rays form an image of the object in the camera, while the reflected rays reflect the image so that it is visible to the eye.

The DuPage Freight Shipping Company charges the following rates: Weight of Package Rate per Pound 2 pounds or less $1.10 Over 2 pounds, but not more than 6 pounds $2.20 Over 6 pounds, but not more than 10 pounds $3.70 Over 10 pounds $3.80 Design a program that does the following: asks the user to enter the weight of a package and displays the shipping charges. 1. Prompt the user for the weight of a package 2. Determines the rate per pound in a getRate module 3. Calculates and displays the total shipping charge in a getTotal module Hint - you may want to use a global variable for this! Please submit three things:
Answer:
The program in Python is as follows:
def getRate(weight):
if weight<=2.0:
rate = 1.10
elif weight>2 and weight<=6:
rate = 2.20
elif weight>6 and weight<=10:
rate = 3.70
else:
rate = 3.80
return rate
def getTotal(weight,rate):
total = weight * rate
print("Total: ",total)
weight = float(input("Weight: "))
rate = getRate(weight)
getTotal(weight,rate)
Explanation:
This defines the getRate function
def getRate(weight):
The following if conditions determine the corresponding rate based on the value of weight passed to the function
if weight<=2.0:
rate = 1.10
elif weight>2 and weight<=6:
rate = 2.20
elif weight>6 and weight<=10:
rate = 3.70
else:
rate = 3.80
This returns the rate back to the main method
return rate
The getTotal module begins here
def getTotal(weight,rate):
This calculates the total charges
total = weight * rate
This prints the calculated total
print("Total: ",total)
The main begins here
This gets input for weight
weight = float(input("Weight: "))
This gets the rate from the getRate function
rate = getRate(weight)
This passes values to the getTotal function
getTotal(weight,rate)
