How many minutes does it take light from the sun to reach earth? (the distance from the sun to earth is 93 million mi; the speed of light = 3.00 ✕ 108 m/

The speed of light is given which is 3*10˄8 = 300,000,000 m/s 
93,000 miles = 149,668,992 000 meters - distance from sun to earth 
149,668,992,000/300000000 = 498.9 seconds - time for light from sun to reach earth 
498.9 seconds/60 seconds per minute = 8.3 minutes - time for light from sun to reach earth 

So the answer is approximately 8 minutes.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
