The power transmitted by the wave is 21.1 W.

<h3>Speed of the wave</h3>

The speed of the wave is determined from general wave equation as shown below;

y = A sin(ωt - kx)

where;

A is amplitude of the wave
ω is angular frequency
k is wave number

v = ω/k

given equation, y = = 0.15 sin (0.80x - 50t)

v = 50/0.8

v = 62.5 m/s

<h3>Power transmitted by the wave</h3>

P = ¹/₂μω²A²v

where;

μ is mass per unit length = 12 g/m = 0.012 kg/m

P = 0.5(0.012)(50²)(0.15²)(62.5)

P = 21.1 W

Thus, the power transmitted by the wave is 21.1 W.

2. An alternating current is represented by the equation I=20sin 100mt.

Sladkaya [172]

Explanation:

The general equation of an AC current is given by :

$I=I_o sin\omega t$

Where

I₀ is the peak value of current

$\omega$ is angular frequency

$As\ \omega=2\pi f$

So,

$f=\dfrac{\omega}{2\pi}\\\\f=\dfrac{100\pi}{2\pi}\\\\f=50\ Hz$

We know that,

$I_{rms}=\dfrac{I_0}{\sqrt{2}}\\\\=\dfrac{20}{\sqrt{2}}\\\\I_{rms}=14.14\ A$

So, the frequency is 50 Hz and the maximum rms value of current is 14.14 A.

What quantities determine the resistance of a piece of material? Choose all that apply.

bija089 [108]

Answer:

Option (a), (b) and (c)

Explanation:

The resistance of a conductor depends on the length of the conductor, area of crossection of the conductor and the nature of the conductor.

The formula for the resistance is given by

R = ρ x l / A

Where, ρ is the resistivity of the conductor, l be the length of the conductor and A be the area of crossection of the conductor.

So, It depends on the length, area and the type of material.
