Suppose the green car was traveling at 0 miles the white car was traveling at 70 miles at the red car was trailing at 22 miles w
Elan Coil [88]

Answer:

The white car will cover the most distance every second.

Explanation:

The formula for the uniform speed of an object is given as follows:

s = vt

where,

s = distance covered by the object

v = speed of the object

t = time required

Now, if we assume time to be  constant at 1 s. Then the distance covered by each car will be directly proportional to the speed of the car. Hence, the car with the greatest speed will travel the greatest distance in 1 second.

We, have:

Speed of white car > Speed of red car > Speed of green car

<u>Therefore, the white car will cover the most distance every second.</u>

The tuner begins by muting the right and center A4 strings. He then strikes the A4 key, and tunes the left A4 string to be exact
Anna [14]

Answer:

f= 440.4 Hz or f= 439.6 Hz

Explanation:

In this exercise we have two waves with slightly different frequencies, the A4 chord with f = 440 Hz and the beating with the central chord fbeats = 0.40 Hz, let's use the relation

               f_{beat} = | f - f₀ |

               f = fo + - f _{beat}

               f = 440 + 0.4 = 440.4 Hz

               f = 440-0.4 = 439.6 Hz
