Suppose you drive 1500 m due east in 2 minutes. You then turn due north and drive the same distance in the same time. Which of t
ahrayia [7]

Answer:

(b) The average speeds are the same, but the average velocities are different

Explanation:

Given,

  • Distance traveled in the east direction = 1500 m
  • time take = t = 2 sec
  • Distance traveled in the north direction = 1500 m
  • time taken = t = 2 sec,

Hence the distance traveled in both the direction is the same of 1500 m in the same time of interval t = 2 sec,

We know that the average speed is the ratio of the total distance traveled and the total time is taken. And the speed does not depends upon the direction of the distance traveled. Thus in both cases, average speeds are the same

But in case of the average velocity, average velocity is equal to the ration of the total displacement and the total time is taken, and also it depends upon the direction of the displacement because the velocity is a vector quantity.

In both the magnitude of the case of the velocities are the same but the direction of the velocities is different, due to this the average velocities in both the cases are different.

Therefore the option (b) the average speeds are the same and the average velocities are different, is correct.

A sound wave takes 0.2 seconds to travel 306 meters.
chubhunter [2.5K]

Answer:

1530 m/s

Explanation:

Given that :

Speed = distance / time

Travel time take = 0.2 s

Distance covered = 306 metres

The speed of sound in the material :

Speed = distance / time = 306 m / 0.2

Speed = 1530 m/s
