Question

1. Find the distance travelled by light in one hour, given that th
speed of light is 100 000 kilometres per second.
Give the answer in kilometres in standard form.​

Answer 1

Answer:

$the \: distance \: \boxed{s} \: is \to \\\boxed{ s = 3.6 \times {10}^{8} \: km}.$

Step-by-step explanation:

$if \: the \: speed \: of \: light \: is : 100 \: 000 \: km {(s)}^{ - 1} \\ if \: the \: time \:o f \: travel\: is : 1hr \: (1 \times 60 \times 60) = 3,600s \\ the n \: the\: distance \: is \: given \: by : \\ s = vt = 1.0 \times {10}^{5} \times 3600 \\ s = 360,000,000 \: km \\ in \: standard \: form \: the \: distance \: \boxed{s} \: is : \\ s = 3.6 \times {10}^{8} \: km$
