Use the information in the table about four different electric circuits to answer the question
ycow [4]

Answer:

Circuit 4

Explanation:

To know the correct answer to the question given above, we shall determine the current in each circuit. This can be obtained as follow:

For circuit 1:

Resistance (R) = 0.5 ohms

Voltage (V) = 20 V

Current (I) =?

V = IR

20 = I × 0.5

Divide both side by 0.5

I = 20 / 0.5

I = 40 A

For circuit 2:

Resistance (R) = 0.5 ohms

Voltage (V) = 40 V

Current (I) =?

V = IR

40 = I × 0.5

Divide both side by 0.5

I = 40 / 0.5

I = 80 A

For circuit 3:

Resistance (R) = 0.25 ohms

Voltage (V) = 40 V

Current (I) =?

V = IR

40 = I × 0.25

Divide both side by 0.25

I = 40 / 0.25

I = 160 A

For circuit 4:

Resistance (R) = 0.25 ohms

Voltage (V) = 60 V

Current (I) =?

V = IR

60 = I × 0.25

Divide both side by 0.25

I = 60 / 0.25

I = 240 A

SUMMARY

Circuit >>>>>> Current

1 >>>>>>>>>>> 40 A

2 >>>>>>>>>>> 80 A

3 >>>>>>>>>>> 160 A

4 >>>>>>>>>>> 240 A

From the above calculation, circuit 4 has the greatest electric current.

Select the ion.<br><br> a) NO2<br> b)H2SO4<br> c) Al+3 ...?
Gemiola [76]
I believe the correct answer from the choices listed above is the third option. The ion would be Al+3. It is obvious because among the options, this is the only substance that has a charge. <span>An </span>ion<span> is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. </span>

<h2>A  sample of gold (Au) has a mass of 72.04g. Calculate the number of atoms of gold (Au): It is equal to ==2.207 x 10²³ number of atoms </h2>

Explanation:

we can find number of atoms in a given sample by the formula :

Number of atoms = Given mass /atomic mass  x Avogadro's number

or , it can be written as :

Number of atoms = given mass /atomic mass x 6.022 x 10²³

Now in above asked question , the values given are :

Mass of sample of gold = 72.04g

Atomic mass of gold : 196.6

Avogadro's number = 6.023 x 10²³

so, using the above formula we have :

Number of atoms = 72.04 /196.6 x 6.022 x 10²³

= 0.3664 x 6.022 x 10²³

=2.207 x 10²³ number of atoms

During which change is heat energy released
Semenov [28]

Answer:

During the uncoupling of electron transport chain energy that is generated by the transport of electron along with proton, is released as heat.

Explanation:

The proton motive force generate energy for the phosphorylation of ADP with inorganic phosphate to form ATP an energy rich molecule during the process called oxidative phosphorylation.

      There are some chemical agents knowns as uncouplers for examole thermogennin,2'4-dinitophenyl.They does not interfere with the transport of electrons through various electron carriers which generate energy,but uncouplers blocks the phosphorylation step.

    As a result the energy that is released during transport of electron, is  liberated as heat.
