6. Dan wants to create acceleration. He

d. Maintain constant velocity

Explanation:

A constant velocity leads to no acceleration.

Acceleration is defined as the change in velocity with time:

  Acceleration = \frac{change in velocity}{time taken}

If there is no change in velocity i.e constant velocity.

At constant velocity, the change in velocity is 0.

 If we put zero in the equation above, we will obtain an acceleration value of 0.

A wire, 1.0 m long, with a mass of 90 g, is under tension. A transverse wave is propagated on the wire, for which the frequency
Mice21 [21]

Answer:

T = 712.9 N

Explanation:

First, we will find the speed of the wave:

v = fλ

where,

v = speed of the wave = ?

f = frequency = 890 Hz

λ = wavelength = 0.1 m

Therefore,

v = (890 Hz)(0.1 m)

v = 89 m/s

Now, we will find the linear mass density of the wire:

\mu = \frac{m}{L}

where,

μ = linear mass density of wie = ?

m = mass of wire = 90 g = 0.09 kg

L = length of wire = 1 m

Therefore,

\mu = \frac{0.09\ kg}{1\ m}

μ = 0.09 kg/m

Now, the tension in wire (T) will be:

T = μv² = (0.09 kg/m)(89 m/s)²

<u>T = 712.9 N</u>
