Answer:

Mass of the ring is 2.5 kg.

Given:

Moment of inertia of a ring = 0.4 kg.m^{2}

Radius = 40 cm = 0.4 m

To find:

Mass of the ring = ?

Formula used:

I = m r^{2}

Where I = moment of inertia

r = radius of the ring

m = mass of the ring

Solution:

Moment of inertia of a ring is given by,

I = m r^{2}

Where I = moment of inertia

r = radius of the ring

m = mass of the ring

0.4 = m ×0.4×0.4

m = 0.4/(0.4×0.4)

m = 1/0.4

m = 2.5 kg

Mass of the ring is 2.5 kg.

The auditory canal behaves like a resonant tube to aid in hearing. One end terminated at the eardrum, while the other opens to t
kompoz [17]

Answer:

3.6 kHz

Explanation:

The pipes behave like a closed pipe . The end open is the end of the air canal outside the ear and the closed end is the eardrum.

The first harmonic will be as seen in the figure attached.

The length of the first harmonic will be λ/4.

λ/4=2.4 cm

λ=2.4 * 4=9.6 cm 0.096 m

Speed of Sound- 344 m/s(in air)

velocity(v) * Time Period(T) = Wavelength (λ)

Also, Time Period(T)= \frac{\textrm{1}}{\textrm{Frequency(f)}}

\frac{\textrm{Velocity}}{\textrm{Wavelength}}=\frac{\textrm{1}}{\textrm{Time Period}} =Frequency

Plugging in the values into the equation,

Frequency = \frac{344}{0.096} Hz

                  = 3583.3 Hz≈3600 Hz= 3.6 kHz

Frequency= 3.6 kHz

Enrique is given information about a satellite orbiting Earth. R = 3. 8 Ă— 108 m T = 18 days In order to calculate the tangentia
NISA [10]

The first step that  Enrique must take in order to calculate the tangential speed of the satellite is to convert the period from days to seconds.

We know that the SI unit of speed is meter per second and now, we with to obtain the tangential speed of the satellite.

Since the period is given in days, the first step is to convert the period from days to seconds.
