What are the two basic kinds of electronic signals?

I'm guessing that what you're really asking is: 

             "What are the two fundamental ways to add
              information to an electronic signal ?"

Information is added to an electronic signal in either analog form
or digital form.

For a couple of decades now, we've gotten so good that we can do
both at the same time, making an electronic signal carry MORE
information that way.

Ibelieve your answer is b.hope this : )

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
