The toll program illustrates the use of conditional statements;
As a general rule, conditional statements are used to make decisions
<h3>The
toll program</h3>
The toll program written in Python where conditional statements are used to make several decisions is as follows:
def calc_toll(hour, morning, weekend):
toll_fee = 0
if weekend == False:
if morning == True:
if hour < 7:
toll_fee+=1.15
elif hour < 10:
toll_fee+=2.95
elif hour <= 12:
toll_fee+=1.90
else:
if hour < 3:
toll_fee+=1.90
elif hour < 8:
toll_fee+=3.95
elif hour >= 8:
toll_fee+=1.40
else:
if morning == True:
if hour < 7:
toll_fee+=1.05
elif hour <= 12:
toll_fee+=2.15
else:
if hour < 8:
toll_fee+=2.15
elif hour >= 8:
toll_fee+=1.10
return toll_fee

Answer:
Effort = 120 Newton
Explanation:
Given the following data;
Mechanical advantage = 6
Load = 780 N
To find the effort required to lift the weight;
Mechanical advantage can be defined as the ratio of the load (weight) lifted by a simple machine to the effort (force) applied.
Mathematically, the mechanical advantage is given by the formula;
Making effort the subject of formula;
Substituting into the formula, we have;
Effort = 120 Newton.
