When a solar flare occurs, how long does it take before a scientist sees it? (The Earth-Sun distance is 1.5*10^11m and the speed of light is approximately 3*10^8 m/s.

It will take 500 seconds before the scientist sees the solar flare

Step-by-step explanation:

From the question, the Earth-Sun distance is 1.5×10¹¹ m and the speed of light is approximately 3×10⁸ m/s.

Now, we are to determine how long it will take before a scientist sees a solar flare after it has occurred. That is, we are to determine time.

From the formula

Speed = Distance / Time

Time = Distance / Speed

From the question,

Distance = 1.5×10¹¹ m

and speed = 3×10⁸ m/s

Therefore,

Time = 1.5×10¹¹ m / 3×10⁸ m/s

∴ Time = 0.5 × 10³ s

Time = 500 s

Hence, it will take 500 seconds before the scientist sees the solar flare.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
