Image distance (Di) = 17 cm
Object distance (Do) = 36 cm
Using mirror equation,
1/Di + 1/Do = 1/f
1/17 + 1/36 = 1/f
0.058824 + 0.027777 = 1/f
1/f = 0.086601
f= 11.5472 = 11.55 cm
Answer:
○ 0
Explanation:
Even if the athelete runs four laps of a 400 m track, its displacement will be 0 because the displacement is the shortest distance from its to final position. And, here the final and initial position is same since he comes to its initial position after covering certain distance. So, displacement is 0.
I think 4800m, not sure though
What’s the question? Is it true or false?
