If a photon of light leaves the sun than reachers the earth 494 second later. what is the distance from the earth to sun

Speed of light = 3 x 10⁸ m/s

Time to make the trip = 494 sec

Distance = (speed) x (time)

Distance = (3 x 10⁸ m/s) x (494 s)

Distance = 1,482 x 10⁸ meters

Distance = 1.482 x 10¹¹  meters

Distance = 1.482 x 10⁸  kilometers

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
