If a magnet is put inside one coil of wire a voltage is produced. What will happen if the magnet is put inside two coils of wire
atroni [7]
The choices can be found elsewhere and as follows:

A)There will not be a change. 
<span>B)The voltage will decrease by a factor of two. </span>
<span>C)The voltage will increase by a factor of two. </span>
<span>D)The two coils of wire will cancel out the magnetic field. </span>
<span>E)The voltage will be zero.
</span>
I believe the answer is option C. If the magnet is put inside two coils of wire, then the  voltage will increase by a factor of two. Hope this answers the question.

What is the average translational KE of 5 moles of gas molecules at 300 K?
aev [14]

Answer:

What is the average translational kinetic energy of molecules in an ideal gas at 37°C? The average translational energy of a molecule is given by the equipartition theorem as, E = 3kT 2 where k is the Boltzmann constant and T is the absolute temperature.

Explanation:

The average translational energy of a molecule is given by the equipartition theorem as, E = 3kT 2 where k is the Boltzmann constant and T is the absolute temperature.

A manufacturer sells two goods, one at a price of $1000 a unit and the other at a price of $16,500 a unit. A quantity q1 of the
vaieri [72.5K]

Answer:

manufacturing cost = $16.5 q₂ + $1 q₁ - $ 5

Explanation:

given,

one unit price of  first good is = $ 1000

one unit price of second good is = $ 16500

quantity of the first good = q₁

quantity of the second good = q₂                      

total cost to the manufacturer =  $ 5000

revenue from  good one = $1000 q₁                    

revenue from second good = $16500 q₂                      

manufacturing cost = total revenue - total manufacturing cost

manufacturing cost = $16500 q₂ + $1000 q₁ - $ 5000        

but in the question we have to answer in thousands of dollar

so, divide the result by 1000                  

manufacturing cost = $16.5 q₂ + $1 q₁ - $ 5

If a display has a dynamic range of 20 dB and the smallest voltage it can handle is 200 mV, then the largest voltage it can hand
DedPeter [7]

Answer:

The largest voltage is 0.02 V.

(d) is correct option.

Explanation:

Given that,

Range = 20 dB

Smallest voltage = 200 mV

We need to calculate the largest voltage

Using formula of voltage gain

G_{dB}=10 log_{10}(\dfrac{V_{out}^2}{V_{in}^{2}})

20 =10 log_{10}(\dfrac{V_{out}^2}{V_{in}^{2}})

2=log_{10}(\dfrac{V_{out}^2}{V_{in}^{2}})

10^2=\dfrac{V_{out}^2}{V_{in}^{2}}

\dfrac{V_{out}}{V_{in}^}=10

V_{in}=\dfrac{V_{out}}{10}

V_{in}=\dfrac{200}{10}

V_{in}=20\ mV

V_{in}=0.02\ V

Hence, The largest voltage is 0.02 V.
