Hunter-Best [27]2 years ago
4 0

Answer:

I X j = k       (perpendicular to plane)

j X k = 0

i X k = 0       cross products for vectors i, j, k  

Flux = B dot A    and only B in the k direction is relevant

Flux = .550 T * .0435^2  m^2 = .00104 Webers-m^2

A stationary boat bobs up and down with a period of 2.4 s when it encounters the waves from a moving boat.
lapo4ka [179]
It seems like the question is asking for the frequency.
Given: 
Time period (T) = 2.4 sec

Frequency (f) =? 

We know that the formula for frequency is:

Frequency (f) = 1/time period (T) 

= 1 / 2.4 s 

= 0.42 Hz. is the frequency for this problem.

Pls help i begg youuuuu
Anna [14]
Pitch is the sensation of certain frequencies to the ear. High frequency = high pitch, low frequency = low pitch. 

f = c(speed of the wave) /  <span>λ (wavelength)

1. 343m/s / 0.77955m = 439.99 Hz   
     This corresponds to pitch A 

2. 343m/s / 0.52028m = 659.26 Hz
</span>     This corresponds to pitch E 
<span>
3. 343m/s / 0.65552m = 523.349 Hz
    </span>This corresponds to pitch C

4. using f = c /  λ
  λ = c / f<span>
     = 343m/s / 587.33 = 0.583999 m = 0.584 m
