Question

I need answer on this problem tyt​

Answer 1

Speed of light:

$3.05 \times 10 ^{8} m/s$

Seconds in a year:

$3.15 \times 10 ^{7}$

$\rule{300pt}{3pt}$

Multiply the speed of light with seconds in a year

*Note:- We will not change the values because speed of light is in m/s and the time is also given in seconds.

$\rule{300pt}{3pt}$

$3.08 \times 10 ^{8} \times 3.15 \times 10 ^{7}$

$(3.05 \times 3.15) \times (10 ^{8} \times 10 ^{7} )$

$9.4675 \times 10 ^{15}$

$\tt9.46 \: Trillion \: Kilometers$
