Answer:

<em>k = 25.18 N/m</em>

Explanation:

<u>Simple Harmonic Oscillator</u>

It consists of a weight attached to one end of a spring being allowed to move forth and back.

If m is the mass of the weight and k is the constant of the spring, the period of the oscillation is given by:

\displaystyle T=2\pi {\sqrt {\frac {m}{k}}}

If the period is known, we can find the value of the constant by solving for k:

\displaystyle k=m\left(\frac{2\pi}{T}\right)^2

Substituting the given values m=5 Kg and T=2.8 seconds:

\displaystyle k=5 \left(\frac{2\pi}{2.8}\right)^2

k = 25.18 N/m

A panpipe is made of five pipes. The longest pipe is 25 centimeters long
Marysya12 [62]
The pipe that produces the highest-frequency sound is the 5 cm long pipe. 

According to the Fundamental Principle, the length of the tube of the pipe and its frequency is inversely proportional. 

This means that the longer the tube, the lower the frequency and vice versa. Therefore, between the 25cm long pipe and the 5cm long pipe, the shorter pipe produces the highest-frequency sound.

A northbound train and a southbound train meet each other on parallel tracks heading in opposite directions. The northbound trai
SSSSS [86.1K]

Answer:

50mph,60mph

Explanation:

Let speed of southbound train=x mph

Speed of northbound train,y=x+16 mph

Distance between two trains after 1.5 hour,174 miles.

We have to find the speed of two trains.

Distance=speed\times time

Using the formula

174=1.5x+1.5(x+16)

174=1.5(x+x+16)

174=(2x+16)\times 1.5

174=3x+24

3x=174-24=150

x=\frac{150}{3}=50mph

y=x+16=50+16=66mph
