Acar starting at position 16m travels out to position 67m and turns around and speeds back to position 16m. what was the displacement of the car?

a 0m

b 16m

c 67m

d 102m

Displacement, D = 0

Explanation:

The initial position of the car is at 16 m. It travels out to position 67 m and turns around and speeds back to position 16 m. Finally, it reaches to a position of 16 m.

We know that the displacement of an object is equal to the shortest path covered by it.

Displacement = final position -initial position

D = 16 m - 16 m

D = 0

So, the displacement of the car during the entire journey is 0. Hence, this is the required solution.

answer and explanation;

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
