Light travels at precisely <span>299,792,458 metres every second (abbreviated to 3 x 10^8 metres every second but let's be precise)
There are 60 seconds in every minute (</span><span>299 792 458 x 60 = 17,987,547,480m)
60 minutes in every hour (17,987,547,480 x 60 = 1,079,252,849,000m)
96 hours in 4 days (</span><span>1,079,252,849,000 x 96 = 10,360,827,350,000m)
</span><span>Now let's convert to km to make this number (slightly) more manageable
(</span>10,360,827,350,000 / 1000 = <span>103,608,273,500km)
</span>Light travels <span>103,608,273,500km in 4 days - that's the equivalent of going around the equator of the earth 813,124 times!</span><span>

Because it can be compressed.

Answer:
S and p blocks elements are considered metals while d-block elements are considered transition metals.
Explanation:
s-block consist of lithium, sodium, potassium, rubidium, cesium and francium metals.
All are these called alkali metals.
These metals have one valance electron.
These metals are soft and having low density.
They easily lose their one valance electron and form cation with +1 charge.
They have low melting points.
P- block elements includes beryllium, magnesium, calcium, strontium, barium, radium metals.
They are called alkaline earth metals.
All are these have two valance electrons.
They easily lose their valance electrons and form cation with charge of +2.
These metals are also very soft.
They form salt with halogens.
They are also very reactive metals.
