James and haley went to the speedway to watch cars race around an oval track. one car traveled at a constant speed for the entire race. james told haley that the car was accelerating during race, but haley said james was wrong since the car traveled at a constant speed. who was right and why? race car image from pixabay. com question 17 options: james was right since the car changed direction during the race. haley was right because the car traveled at a constant speed. acceleration is a change in velocity. james was right because the car was a race car and all race cars accelerate during a race. haley was right since the car didn't win the race it was not accelerating.

James was right since the car changed direction during the race

Explanation:

Acceleration is defined as the rate of change of velocity per unit time:

This means that an object is accelerating whenever there is a change in its velocity. However, velocity is a vector: this means that it has both a magnitude (the speed) and a direction. Therefore, we can say that an object is accelerating when there is a change either in its speed or in its direction.

In this problem, the car travels at constant speed around an oval track: its speed remains constant, but its direction constantly changes, since hte track is oval. Therefore, the velocity of the car changes, so the car is accelerating, and James is right.

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

ill do it for 100, also this isnt 80 its 40
