jarptica [38.1K]4 years ago
5 0

Answer:

\frac {f_i}{\sqrt 2}

Explanation:

Frequency is given by \frac {1}{2\pi}\sqrt{{\frac {k}{m}}

Let the initial frequency be denoted by f_i

f_i=\frac {1}{2\pi}\sqrt{{\frac {k}{M}}

When M is 2M then

f_f=\frac {1}{2\pi}\sqrt{{\frac {k}{2M}}=\frac {f_i}{\sqrt 2}

Therefore, the final frequency is

\frac {f_i}{\sqrt 2}

A 0.25-kg ball attached to a string is rotating in a horizontal circle of radius 0.5 m. If the ball revolves twice every second,
Aloiza [94]

Answer:

19.74 N

Explanation:

mass of ball (m) = 0.25 kg

radius (r) = 0.5 m

time (t) = 2 revolutions per seconds = 1/2 = 0.5 second per revolution

find the tension in the string

tension (T) = \frac{mv^{2} }{r}

  • where velocity (v) = \frac{2πr}{t}

tension now becomes (T) = \frac{m}{r} x (\frac{2πr}{t})^{2}

tension (T) = \frac{4π^{2}rm }{t^{2} }

  • now substituting the values of mass (m), time (t) and radius (r) into the equation above we have

tension (T) = \frac{4π^{2}x0.5x0.25}{0.5^{2} }

tension (T) =  2π^{2} =   2x3.142^{2} = 19.74 N

A phone cord is 2.28 m long. The cord has a mass of 0.2 kg. A transverse wave pulse is produced by plucking one end of the taut
Debora [2.8K]

The characteristics of the speed of the traveling waves allows to find the result for the tension in the string is:  

         T = 10 N

The speed of a wave on a string is given by the relationship.

      v =\sqrt{\frac{T}{\mu } }

Where   v es the velocty, t is the tension ang μ is the lineal density.

They indicate that the length of the string is L = 2.28 m and the pulse makes 4 trips in a time of t = 0.849 s, since the speed of the pulse in the string is constant, we can use the uniform motion ratio, where the distance traveled e 4 L

           v = \frac{d}{t}  

           v = \frac{4 L}{t}  

           v = \frac{4 \ 2.28 }{0.849}  

            v = 10.7  m / s

Let's find the linear density of the string, which is the length of the mass divided by its mass.

            μ = \frac{m}{L}  

            \mu = \frac{0.2}{2.28}  

            μ = 8.77 10⁻² kg / m

The tension is:

        T = v² μ

Let's calculate

        T = 10.7²  8.77 10⁻²

        T = 1 0 N

In conclusion using the characteristics of the velocity of the traveling waves we can find the result for the tension in the string is:

         T = 10 N
