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.

Answer:
Work done by the frictional force is
Explanation:
It is given that,
Mass of the car, m = 1000 kg
Initial velocity of car, u = 26.1 m/s
Finally, it comes to rest, v = 0
We have to find the work done by the frictional forces. Work done is equal to the change in kinetic energy as per work - energy theorem i.e.
W = −340605 J
or
Hence, the correct option is (a).
The correct answer for the question that is being presented above is this one: "C. The negative terminal of the source of voltage is connected to the N-type material within a reverse-biased setup." the statement that accurately describes junction diodes is that t<span>he negative terminal of the source of voltage is connected to the N-type material within a reverse-biased setup. </span>
