Answer:

400 Hz

Explanation:

The frequency of a sound wave is found by the velocity/wavelength.  Therefore, f = v/wavelength = (200 m/s)/(0.5 m) = 400 Hz

I hope this helps! :)

A venturi is constructed of a 10.0 cm pipe with a 2.0 cm diameter throat. Water pressure in the pipe is twice atmospheric pressu
postnew [5]

Answer:

P_t=5066250.0696\ Pa=50\ atm

Explanation:

Given:

  • diameter of pipe, d=0.1\ m
  • diameter of throat, d_t=0.02\ m
  • velocity of flow, v=0.4\ m.s^{-1}

<u>Pressure in the pipe is twice the atmospheric pressure:</u>

P=2\times 101325=202650\ Pa

<u>Now the force of flow of water:</u>

F=P\times A

<u>now we find cross sectional area of the pipe:</u>

A=\frac{\pi.d^2}{4}

A=\pi \times\frac{0.1}{4}

A=0.007854\ m^2

<u>Therefore,</u>

F=202650\times 0.007854

F=1591.6094\ N

<u>Now the area at throat:</u>

A_t=\frac{\pi.d_t^2}{4}

A_t=\frac{\pi\times 0.02^2}{4}

A_t=0.000314\ m^2

<u>Therefore pressure at throat:</u>

P_t=\frac{F}{A_t}

P_t=\frac{1591.6094}{0.000314}

P_t=5066250.0696\ Pa=50\ atm

Coulomb's law is similar to newton's law of gravitation in several ways. which one of the statements is not a similarity between
PIT_PIT [208]

The only dissimilarity between Coulomb's law and Newton's law of gravitation other than the type of force considered is Newton's law only considers negative force while Coulomb's law considers both forces.

In these contexts, it is considered that repulsive forces are positive and attractive forces are negative. So, Newton's law of gravitation considers gravitational force which only attracts. So, Newton's law of gravitation takes only negative force into account while Coulomb's law considers both electric charges.

According to Newton's law of gravitation,

F = G m_{1} m_{2} / r^{2}

According to Coulomb's law

F = k q_{1} q_{2} / r^{2}

Therefore, the only dissimilarity between Coulomb's law and Newton's law of gravitation other than the type of force considered is Newton's law only considers negative force while Coulomb's law considers both positive and negative forces.
