The equation of a progressive

Juliette [100K]

Answer:

Amplitude = 0.02m

Frequency = 640 Hz

Wavelength, λ = 0.5m

v = 320 m/s

Explanation:

Given the wave equation :

y=0.02 sin2π/0.5 (320t - x) where x and y are in

meters and t is in second

Comparing the above relation with the general wave equation :

y(x, t) = Asin2π/λ(wt - kx)

The amplitude, A = 0.02

From the equation :

2π/0.5 = 2π/λ

λ = 0.5 m

320t = vt

Hence, v = 320 m/s

Recall :

v = fλ

320 = f * 0.5

f = 320 / 0.5

f = 640 Hz

Ask Your Teacher A coil is formed by winding 260 turns of insulated 16 gauge copper wire (diameter = 1.3 mm) in a single layer o

Liula [17]

Answer:

The resistance is $2.98$ Ω

Explanation:

<u>Data</u>

diameter: $d=1.3mm$ , $d=1.3*10^{-3} m$

Radius: $r=\frac{d}{2} ,r=\frac{1.3*10^{-3} }{2} ,r=6.5*10^{-4} m$

Resistivity constant: $p=1.65*10^{-8}$ Ω $m$

To find Area:

$A=\pi r^{2} \\A=\frac{22}{7} *(6.5*10^{-4} )\\A=1.33*10^{-6} m^{2}$

To find circumference:

$l=260*(2\pi (0.15))\\l=245.04m$

Now we can apply the Resistivity formula:

$R=p\frac{l}{A}$

$R=(1.65*10^{-8} )$ Ω $m*\frac{240.04m}{1.33*10^{-6}m^{2} }$

$R=2.98$ Ω
