1.7 Btu
1 watt = 3.41214 Btu/h
1watt * 1h = 3.41214 Btu/h * h
1 = 3.41214 Btu/ (watt*h)/
0.5 watt * h = 0.5 watt*h * 3.41214 Btu/(watt*h) = 1.706 Btu

Dear Amrish
I have come to know that since your school has closed for the Autumn Break you have plenty of free time at your disposal at the moment. I would like to tell you that even I am having holidays now.
It has been a long time since we have spent some time together. If you are free, I would welcome to have your company this weekend. Why don’t you come over to my house and spend a day or so with me?
I am anxiously waiting for your reply.
Yours affectionately
your name
Answer:
it bc the adults are bigger then us kid so when they dip in the pool it makes bigger splashes
Explanation:
Answer:
The minimum inductance needed is 2.78 H
Explanation:
Given;
frequency of the AC, f = 26.5 Hz
the root mean square voltage in the circuit,
= 41.2 V
the maximum current in the circuit, I₀ = 126 mA
The root mean square current is given by;
![I_{rms} = \frac{I_o}{\sqrt{2} } \\\\I_{rms} = \frac{126*10^{-3}}{\sqrt{2} }\\\\I_{rms} =0.0891 \ A](https://tex.z-dn.net/?f=I_%7Brms%7D%20%3D%20%5Cfrac%7BI_o%7D%7B%5Csqrt%7B2%7D%20%7D%20%5C%5C%5C%5CI_%7Brms%7D%20%20%3D%20%5Cfrac%7B126%2A10%5E%7B-3%7D%7D%7B%5Csqrt%7B2%7D%20%7D%5C%5C%5C%5CI_%7Brms%7D%20%20%3D0.0891%20%5C%20A)
The inductive reactance is given by;
![X_l = \frac{V_{rms}}{I_{rms}} \\\\X_l= \frac{41.2}{0.0891}\\\\X_l = 462.4 \ ohms](https://tex.z-dn.net/?f=X_l%20%3D%20%5Cfrac%7BV_%7Brms%7D%7D%7BI_%7Brms%7D%7D%20%5C%5C%5C%5CX_l%3D%20%5Cfrac%7B41.2%7D%7B0.0891%7D%5C%5C%5C%5CX_l%20%3D%20462.4%20%5C%20ohms)
The minimum inductance needed is given by;
![X_l = \omega L\\\\X_l = 2\pi fL\\\\L = \frac{X_l}{2\pi f}\\\\L = \frac{462.4}{2\pi *26.5}\\\\L = 2.78 \ H](https://tex.z-dn.net/?f=X_l%20%3D%20%5Comega%20L%5C%5C%5C%5CX_l%20%3D%202%5Cpi%20%20fL%5C%5C%5C%5CL%20%3D%20%5Cfrac%7BX_l%7D%7B2%5Cpi%20f%7D%5C%5C%5C%5CL%20%3D%20%5Cfrac%7B462.4%7D%7B2%5Cpi%20%2A26.5%7D%5C%5C%5C%5CL%20%3D%202.78%20%5C%20H)
Therefore, the minimum inductance needed is 2.78 H
