<h3>Answer:</h3>

60 km/s

<h3>step-step wise explaination:</h3>

60 kilometers / 60 minutes

= 1 kilometer / minute

as we know to convert kilometer / min we should multiply 60 to speed value

therefore, (1×60/ 1) km/hr=60 km/ hr

if you want to know why 60 multiplied with it then read this

1 km/min to km/hr

1 minute = 1/60 hour

so, for converting minute to hour we multiply 1/60

when it goes to top then it multiplied

I know it's little complicated let see it by equation

1 km/min = (1 / 1×1/60) km/h

=(1 / 1/60) km/hr

= 60 km/hr

( note there is no change in km so it remains without multiplied)

If a car moves with a uniform speed of 2m/s in a circle of radius 0.4m, what is its angular speed?
REY [17]

Answer:

The car's angular speed is \frac{rad}{s}.

Explanation:

Angular velocity is usually measured with \frac{radians}{sec}, so I'm going to use that to answer your question.

The relationship between tangential velocity and angular velocity (ω)  is given by:

V = \omega R

Using the values from the question, we get:

2 \frac{m}{s} = \omega (0.4m)

\omega = 5 \frac{rad}{s}

Therefore, the car's angular speed is 5 \frac{rad}{s}.

Hope this helped!

Oksi-84 [34.3K]

Answer:

f1 = 58.3Hz, f2 = 175Hz, f3 = 291.6Hz

Explanation:

lets assume speed of sound is 350 m/s.

frequencies of a standing wave modes of an open-close tube of length L

fm = m(v/4L)

where m is 1,3,5,7......

and fm = mf1

where f1 = fundamental frequency

so therefore: f1 = 350 x 4 / 1.5

f1 = 58.3Hz

f2 = 3 x 58.3

f2 = 175Hz

f3 = 5 x 58.3

f3 = 291.6Hz
