In Fig.25-46,how much charge is stored on the parallel-plate capacitors by the 12.0 V battery? One is filled with air,and the ot
Fittoniya [83]

Answer:

Q=7.9\times 10^{-10}\ C

Explanation:

Given that

V= 12 V

K=3

d= 2 mm

Area=5.00 $ 10#3 m2

Assume that

$ = Multiple sign

# = Negative sign

A=5\times 10^{-3}\ m^2

We Capacitance given as

For air

C_1=\dfrac{\varepsilon _oA}{d}

C_1=\dfrac{\varepsilon _oA}{d}

C_1=\dfrac{8.85\times 10^{-12}\times 5\times 10^{-3}}{2\times 10^{-3}}

C_1=2.2\times 10^{-11}\ F

C_2=\dfrac{K\varepsilon _oA}{d}

C_2=\dfrac{3\times 8.85\times 10^{-12}\times 5\times 10^{-3}}{2\times 10^{-3}}\ F

C_2=6.6\times 10^{-11}\ F

Net capacitance

C=C₁+C₂

C=8.8\times 10^{-11}\ F

We know that charge Q given as

Q= C V

Q=12\times 6.6\times 10^{-11}\ C

Q=7.9\times 10^{-10}\ C

Ethan is using a machine to mix cement. The work input is 10 and the work output is 8. What is the efficiency of the
Arturiano [62]

Efficiency or \eta is calculated by formula: \eta=\frac{W_{output}}{W_{input}} where \eta\leq1 also efficiency has no unit.

Now put in the data and calculate the efficiency.

\eta=\frac{8}{10}=\boxed{0.8}

The efficiency of the machine is 0.8

If you want to get percentage just multiply by 100 and you get 80%

Hope this helps.

liq [111]

Answer: Reduction in skin resistance as a result of increased perspiration leading to conduction.

Explanation:

A lie detector is a machine used to detect when someone is lying.

This is so because when an individual lies, there is an increase in heart beat which causes an increase in sweating. As the the individual sweats there is a reduction in the resistance at skin surface leading to current conduction across the connected cables.
