Answer:

39 m/s

Explanation:

speed = frequency x wavelength (All SI Unit)

speed = 100 Hz x 0.30 m = 30 m/s

A rope is vibrating in such a manner that three equal-length segments are found to be vibrating up and down with 321 complete cy
kolbaska11 [484]

Answer:

<u>2.48 m</u> is the length of the rope.

Explanation:

Cycle period is 321

Time is 20 second

Wave travels at speeds = 26.4 m/s

We know that,

\text { Frequency }=\frac{1}{T} \text { (For one cycle) }

Frequency required for 321 complete cycle in 20 seconds is

\text { Frequency }(f)=\frac{321}{20}

Frequency = 16.05 hz

We know that,

\text { Wavelength }=\frac{\text { wave velocity }}{\text { frequency }}

\lambda=\frac{v}{f}

λ = wavelength, the distance between "wave crests" (m)

v = wave velocity, the "speed" that waves are moving in a direction (m/s)

f = frequency, (cycles/ or Hz)

\lambda=\frac{26,4}{16.05}

λ = 1.65 m

As per given question "length of the rope has three equal length segment"

\mathrm{Length of the rope}=\frac{3}{2} \lambda

\mathrm{Length of the rope }=\frac{3}{2} \times 1.65

\mathrm{Length of the rope}=1.5 \times 1.65

Length of the rope = 2.48 m

Therefore, length of the rope is <u>2.48 m.</u>

A glass bottle of soda is sealed with a screw cap. The absolute pressure of the carbon dioxide inside the bottle is 1.50 x 105 P
MArishka [77]

Answer:

F \approx 19.5 N

Explanation:

From the question we are told that:

Pressure of  P_{CO_2}=1.50 * 105 Pa.

Bottle cap area A_b= 4.40 * 10-4 m^2

 

Generally the equation for Resultant pressure P_r is give as is mathematically given by

P_r=P_{CO_2}-P_a

Where

P_a=atmospheric\ pressure = 1.013*10^5 pa

P_r=1.50 * 105 Pa-1.013*10^5 pa

P_r=0.487*10^5 pa

Generally the equation for Force exerted by screw F is give as is mathematically given by

F = P*A\\F = 0.487*10^5*4.00*10^-4\\ F = 19.48 N

F \approx 19.5 N
