a person walks 750m due north then 250 m due east of the entire walk takes 12 min find the person average velocity​

Answers

Answer:

v = 1.098 m/s

Explanation:

Given that,

A person walks 750m due north then 250 m due east of the entire walk takes 12 min.

We need to find the average velocity of the person.

Displacement,

[tex]d=\sqrt{750^2+250^2} \\\\d=790.56\ m[/tex]

Average velocity = displacement/time

[tex]v=\dfrac{790.56\ m}{12\times 60\ s}\\\\v=1.098\ m/s[/tex]

So, the average velocity of the person is 1.098 m/s.

Two cars approach each other from opposite directions each
with a velocity of 54 km/h. One of the cars emits a note of frequency 480 Hz. What will be the approximate frequency
heard in the other car before they cross each other?

Answers

Answer:524 Hz

Explanation:

Approximate frequency, heard in other car, when two car approaches each other, before they cross each other is 524 Hz.

What is frequency?

Frequency of wave is the number of waves, which is passed thorough a particular point at a unit time.

For the two cars approaching each other the Doppler formula to find the frequency of second car is given as,

[tex]f_2=\dfrac{V_s+V_2}{V_s-V_1}f_1[/tex]

Here, [tex]V_s[/tex] is the speed of the sound.

Two cars approach each other from opposite directions.The velocity of car one is 54 km/h and the velocity of the car two is also 54 km/h.

Convert the unit of velocity of the car as,

[tex]\rm 54km/s=54\times\dfrac{5}{18}m/s\\\rm 54km/s=15m/s[/tex]

As we know that the speed of the sound is 340 m/s and one of the cars emits a note of frequency 480 Hz.

Thus, putting the values in the above formula to find out the frequency heard in the other car before they cross each other as,

[tex]f_2=\dfrac{340+15}{340-15}480\\f_2=524.3\rm Hz[/tex]


The approximate frequency heard in the other car before they cross each other is 524 Hz.

If a sound wave has a wavelength of 0.790 meters, and is travelling at a speed of 355 m/s, what is the period of oscillation for this wave?

Answers

Wavelength=velocity/frequency
Time a.k.a period = 1/frequency

Step 1: solve for frequency using the first equation
0.79m = 355/frequency
Frequency=280.45 Hz

Step 2: solve the period using the second equation

1/280.45 = 0.00357=3.57*10^-3 seconds
