"Calculate the speed of this sound wave by recording how much time it takes to travel 5 meters. Use the (old school) velocity eq

uation: v = d/t Show units in your work. Answer: 292.39 m/s= 5 meters/.0171 secs." and here's the question I need help with: "Based on the speed you measured above, how long would it take for you to hear thunder if you observed lightning and it was seen to be 1620 meters away?"

1) sound velocity reported by you : 292.39 m /s

2) time to travel 1620m at that velocity: t = d / v = 1620 m / 292.39 m/s = 5.54 s, since the moment the sound wave started.

3) You might wanted to tell the time since you watched the lightning.

Then you can calculate the time since the lighting was generated,1620 m away from you, until you saw it, using the speed of light:

 speed of light = 3*10^8 m/s => t = 1620 m / (3*10^8m/s) =0.0000054 s

Then, this time is completely neglectible, and yet the answer is 5.54 s, as calculated in the step 2.

Which is best supported by the data in the chart? Current W flows at a higher rate than Current Z. Current Y flows at a lower ra
LekaFEV [45]
There is no chart provided in this statement. However, the current that flows within an electrically charged item is dependent on how it is arranged. There are two kinds of current and these are, parallel and circuit currents. Current that flows in  parallel current is less than when it is farther away from the electric source; current that flows in a series current flows at a constant rate regardless of how far it is from the electrical source.

Angelina jumps off a stool. As she is falling, the Earth’s gravitational force on her is larger in magnitude than the gravitatio
valentinak56 [21]
The answer is True. The amount force exerted by any object is directly proportional to its mass. This means that our planet is exerting more gravitational force to Angelina, and Angelina is also exerting a gravitational force on our planet directly proportional to her mass. Angelina is actually falling towards the center of the earth,and also our planet is also moving towards Angelina, but it seems negligible with respect to Angelina.Our Sun is so massive that it held our planet in its orbit because of its gravitational force.
