How many times longer does it take light from the Sun to reach Neptune than Mercury? Express this number in standard notation. E
1 answer:
9514 1404 393
Answer:
77.6
Step-by-step explanation:
The ratio of light times will be the ratio of distances:
(light time to Neptune) / (light time to Mercury)
= (Neptune distance)/(Mercury distance)
= (27.93×10^8 mi)/(0.3598×10^8 mi) = 27.93/0.3598
≈ 77.6
It takes about 77.6 times as long for light to reach Neptune as it does to reach Mercury.

Answer:
x=0.996
Step-by-step explanation:
To take natural log ln , we need to get e^2x alone
Subtract 5 on both sides
Now we divide both sides by 3
Now we take 'ln' on both sides
As per log property we can move exponent 2x before ln
The value of ln(e) = 1
Divide both sides by 2
x= 0.996215082
Round to nearest thousandth
x=0.996
