Can someone help me with this please?
Slav-nsk [51]

Answer:

C2, C1, C4, C5 and C6 are in parallel. Therefore, we use the formula Cp = C1 + C2 + ....

Cp = C2 + C1 + C4 + C5 + C6 = ( 7 * 10 ^-3) + (18 * 10^-6) + (0.8F) + (200 * 10^-3 F) + (750 * 10^-6) = 1.008F

Now, Cp will become one capacitor and it will be aligned with C3, therefore it will now become a circuit in series.

We use the formula: 1/Cs = 1/C1 + 1/C2 + .... + ....1/Cn

Thus,

1/Cs = 1/C3 + 1/Cp

1/Cs = 1/(14 * 10^-3 F) + 1/(1.008F)

Cs = 1.4 * 10 ^-2 or if we do not round too much it will give exactly 0.0138 F

So the answer should be a)

A water pump that consumes 2 kW of electric power when operating is claimed to take in water from a lake and pump it to a pool w
Ket [755]

Answer:

The claim is not reasonable

Explanation:

From the question we are told that

The power consumed is P  =  2kW  =  2*10^3 W

The height of the pool's free surface is h = 30 \  m

The rate is Q =  53\ L /s

Given that the rate is 53 liters in 1 second , let say the 1 liter is equivalent to 1 kg so 50 liter = 50 kg

So the workdone by the pump is mathematically represented as

W =  m * g  * h

=>     W =  50  * 9.8  * 30

=>      W =14700 \  J

So what this value is telling us is that 14700 J of work is done in one  second

and generally power is workdone per time thus the power consumed to move water at the given rate is 14.7 kW which is far greater than the power stated in the question so the claim is not reasonable

A statistic is a(n) __________ that describes groups or samples of objects.
irakobra [83]
The answer is number. The statistic is usually a numerical value that we have obtained through the application of different amthematical algorithms to our datasets. Examples of such algorithms include summary measures, the arithmetic mean, the standard deviation, etc. Statistics are used to give us information about our samples and subgroups, whereas parametrs are numerical values that give us infromation about our population values.
