First we need to convert the frequency to the correct SI units (seconds)

Frequency of bell = 1440/60 = 24 Hertz (Strikes per second)

Power is the rate of work being done or the work done per second.

P = E/t = (24 * 0.2)/1 = 4.8 Watt

the candle had 350 J of energy in the chemical store. As it burned, 250 J was transferred by lighting to the surrounding​
Elan Coil [88]

Answer:

Efficiency = 71%

Explanation:

Given the following data:

Output energy = 250 Joules

Input energy = 350 Joules

To find efficiency;

Efficiency = \frac {Out-put \; energy}{In-put \; energy} * 100

Substituting into the equation, we have;

Efficiency = \frac {250}{350} * 100

Efficiency = 0.7143 * 100

Efficiency = 71.43 ≈ 71%

Therefore, the efficiency of the candle is 71 percent.

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

5. Describe the shape of the waveform in the secondary coil for a sine, square and triangle wave in the primary coil. How does t
Volgvan

Answer:

When primary coil is exited by sin wave,this will result in sin wave in secondary coil as well.According to law,flux induced in the secondary coil will have same waveform as in the primary coil.
