Question

Calculate the time taken by the light to pass through a nucleus of diameter 1.56 × 10-16 m. (speed of light is 3× 108 m/s)

CLASS - XI PHYSICS (Physical World & Measurement)

Answer 1

here distance=1.56 x10*-16m  speed of light =3 x10*8m/s   time =?     speed= dist/time      time=dist/speed =1.56 x10*-16 /3 x10*8 =0.52 x10*-24sec

Answer 2

Answer:

5.2 x 10^-25m

Explanation:

We know that distance=speed x time

Therefore, time=distance / speed

                         =1.56 x 10^-16 / 3 x 10^8

                         =0.52 x 10^-24   [1.56/3 = 0.52]

                         =5.2 x 10^-25 [standard form]

Here's your answer......best of luck!!!
