The total power delivered by the battery is 32W.
<h3>
What is total power?</h3>
The total power in a series circuit can be described as one that is equal to the sum of the power that is been dissipated by the individual resistors.
The total power delivered by the battery can be calculated using the formula below:
Pp= [(Δv)^2/ R]
=4 [(Δv)^2/ 2R]
=4Ps
where Ps= power in the series = 8.00 W
R= resistance
=4*8W
=32W
Therefore, total power delivered by the battery is 32W.

Answer:
Frequency = 3.19 * 10^14 Hz or 1/s
Explanation:
Relationship b/w frequency and wavelength can be expressed as:
C = wavelength * frequency, where c is speed of light in vacuum which is 3.0*10^8 m/s.
Now simply input value (but before that convert wavelength into meters to match the units, you do this by multiply it by 10^-9 so it will be 940*10^-9)
3.0 * 10^8 = Frequency * 940 x 10^-9
Frequency = 3.19 * 10^14 Hz or 1/s

Explanation:
Hello!
To solve this problem use the following steps, the procedure is attached.
1. draw the complete outline of the problem
2. Use the continuation equation that states that the volumetric flow at the inlet of the pipe is the same as it should come out, remember that the flow is the product of the cross-sectional area by the flow rate, finally use algebra and input data to Find the exit diameter.

Explanation:
Let assume that cooling water works under a pressure of 1 atmosphere. The time required to boil half of the water is determined by the First Law of Thermodynamics:
![\dot Q \cdot \Delta t = m \cdot [c_{p,w}\cdot (T_{2}-T_{1})+h_{fg}]](https://tex.z-dn.net/?f=%5Cdot%20Q%20%5Ccdot%20%5CDelta%20t%20%3D%20m%20%5Ccdot%20%5Bc_%7Bp%2Cw%7D%5Ccdot%20%28T_%7B2%7D-T_%7B1%7D%29%2Bh_%7Bfg%7D%5D)
![\Delta t = \frac{m\cdot [c_{p,w}\cdot (T_{2}-T_{1})+h_{fg}]}{\dot Q}](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%5Cfrac%7Bm%5Ccdot%20%5Bc_%7Bp%2Cw%7D%5Ccdot%20%28T_%7B2%7D-T_%7B1%7D%29%2Bh_%7Bfg%7D%5D%7D%7B%5Cdot%20Q%7D)
![\Delta t = \frac{(2.25\times 10^{5}\,kg)\left[\left(4.186\,\frac{kJ}{kg\cdot ^{\textdegree}C} \right)\cdot (100\,^{\textdegree}C - 10\,^{\textdegree}C)+2256.5\,\frac{kJ}{kg} \right]}{200000\,kW}](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%5Cfrac%7B%282.25%5Ctimes%2010%5E%7B5%7D%5C%2Ckg%29%5Cleft%5B%5Cleft%284.186%5C%2C%5Cfrac%7BkJ%7D%7Bkg%5Ccdot%20%5E%7B%5Ctextdegree%7DC%7D%20%5Cright%29%5Ccdot%20%28100%5C%2C%5E%7B%5Ctextdegree%7DC%20-%2010%5C%2C%5E%7B%5Ctextdegree%7DC%29%2B2256.5%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D%20%5Cright%5D%7D%7B200000%5C%2CkW%7D)
