Answer:
Boiling point of HF is higher as compared to HCl because of presence of hydrogen bonding in it.
Explanation:
In HF, intermolecular force of attraction is hydrogen bonding.
Hydrogen bonding is a type of electrostatic force of attraction existing between H atom and electronegative atom.
For a molecule to have hydrogen bonding, H atom must be bonded to electronegative atom, O, N and F.
Hydrogen bonding can be intermolecular and intramolecular.
So, in HF hydrogen bonding present.
In HCl, only van der Waals force exists. van der Waals forces are weak as compared to hydrogen bonding.
Because of presence of hydrogen bonding, HF molecules are held tightly and so requires more heat to boil.
Therefore, boiling point of HF is more as compared to HCl.
The five type of new communication method (both wire and wireless) are:
- Social Media
- SMS Text Messaging
- Email Marketing
- Direct Email
- Voice Calling
<h3>What is a communication?</h3>
This means the act of giving, receiving and sharing of information as well as talking, writing, listening or reading.
The types of Communication includes:
- Verbal Communication: It occurs when we engage in speaking with others.
- Non-Verbal Communication: It occurs when what we speak often says more than the actual words.
- Written Communication: It occurs in an actual text or writing.
- Listening: It occurs when we pay attention to a speaker.
The wired communication involves transmission of data over a wire-based communication technology while a wireless communication involves transmission of data without the use of a cable or wire.

the answer is C cause drivers dont always follow the rules
Answer:
The program is given below with appropriate comments for better understanding
Explanation:
#Program
# foot stride = 2.5 feet
# 1 mile = 5280 feet
no_stride_first_min = int(input('Enter the number strides made durng the first minute of jogging: '))
no_stride_last_min = int(input('Enter the number strides made durng the last minute of jogging: '))
avg_stride_one_min = (no_stride_first_min + no_stride_last_min)/2 # calculates the average stride per minute
jogging_duration = float(input('Enter the total time spent jogging in hours and minute: '))
jogging_duration_hours = int(jogging_duration) # gets the hour
jogging_duration_min = jogging_duration - int(jogging_duration) # gets the minute
tot_jogging_duration_min = jogging_duration_hours*60 + jogging_duration_min # calculates total time in minutes
dist_feet = (avg_stride_one_min*2.5)*tot_jogging_duration_min # calculates the total distance in feet
dist_miles = dist_feet/5280 # calculates the total distance in mile
print('Distance traveled in miles = {0:.2f} miles'.format(dist_miles))
Answer:
I think this answer is number B
