Answer:
A. Speed
Explanation:
Speed is the magnitude of velocity, which is given in the question. Velocity is a vector quantity and therefore has both a magnitude and a direction. Only the former is implied in the question.
The offspring can have some features for the parents relatives and can look nothing like the parents. They can look exactly alike to more of one parent then the other or have features from both parents as well

In SI units with dry air at 20*C (68*F), the speed of sound c is 343 meters per second (m/s).
The answers is 343 meters per second:
Answer: A proton would experience the same magnitude of force.
Explanation: The equation relating Force F charge Q and Electric Field E, is given as
E = F/Q
The magnitude of the force felt would be the same since + and - charge as same magnitude from the question (-1C and +1C). But the direction of force of the proton which as a positive charge would be towards/same direction as the Electric Field.
