Light Travel Time from Sun to Earth - HELP-HOMEWORK

AI Thread Summary
To calculate the time it takes for light to travel from the Sun to Earth, one must use the speed of light, which is approximately 186,282 miles per second, and the distance of 93 million miles. By applying the formula time = distance/velocity, the calculation reveals that light takes about 500 seconds, or roughly 8 minutes and 20 seconds, to make this journey. The analogy of driving 25 miles at 25 miles per hour helps clarify the concept of using speed and distance to find time. Understanding this relationship is crucial for solving the homework question. The discussion emphasizes the importance of applying basic physics principles to real-world scenarios.

HELP-HOMEWORK...Hi, I have homework that ask "Using the velocity of light find an approximate value for the amount of time that it takes a light ray to travel from the sun to the earth." Now I know the distance between the Earth and the sun is 93 million miles but I'm not catching on to the question can anyone shed some light for me.(pun intended)

Answer this question first: How long does it take you to drive 25 miles at 25 miles an hour? I bet you know that. Well, your question is the same. You got the velocity (182,000 miles a second -- instead of 25 miles an hour), you have the distance (93 million miles -- instead of 25 miles). Solve it.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
