At room temperature, sound travels at a speed of about 344 m/s in air. You see a distant flash of lightning and hear the thunder

Answer:

$d=1.67mi$

Explanation:

Assuming the light takes essentially no time to reach you, the distance at which the lightning occurred can be calculated by multiplying the speed of sound by the time it takes to hear the thunder:

$d=v_st\\d=344\frac{m}{s}(7.8s)\\d=2683.2m*\frac{1mi}{1609.34m}=1.67mi$

Can someone help me ?

Answer:

1) Time interval Blue Car Red Car

0 - 2 s Constant Velocity Increasing Velocity

2 - 3 s Constant Velocity Constant Velocity

3 - 5 s Constant Velocity Increasing Velocity

5 - 6 s Constant Velocity Decreasing Velocity

2) For Red and Blue car y₂ = 120 v = $\frac{y_{2}-y_{1}}{t_{2}-t_{1}}$ = $\frac{120-0}{6-0}$ = 20 m/s

We get the same velocity for two cars because it is the average velocity of the car at the given interval of time. It is measured for initial and final position.

3) At t = 2s, the cars are the same position, and are moving at the same rate

Position - same

Velocity - same

The position-time graph shares the same spot for two cars.

The Richter Scale is not commonly used anymore, except for small earthquakesrecorded locally, for which ML and Mblg are the only magnitudes that can be measured. For all other earthquakes, the moment magnitude scale is a more accurate measure of the earthquake size.
