For a certain RLC circuit the maximum generator EMF is 125 V and the maximum current is 3.20 A. If le a) the impedance of the ci

MAXImum [283]

Answer:

Part (i)

Z = 39.06 ohm

Part (ii)

R = 21.7 ohm

Explanation:

a) here we know that

maximum value of EMF = 125 V

maximum value of current = 3.20 A

now by ohm's law we can find the impedence as

$z = \frac{V_o}{i_o}$

now we will have

$z = \frac{125}{3.20} = 39.06 ohm$

Part b)

Now we also know that

$\frac{R}{z} = cos\theta$

$\theta = 0.982 rad = 56.3 degree$

now we have

$\frac{R}{39.06} = cos56.3$

$R = 21.7 ohm$

The chemical symbol for the element calcium is Ca. What would be the symbol representing calcium atoms that have lost two electr

Kazeer [188]

Answer:

$ca^{2 + }$

Explanation:

In all atoms, the number of protons = number of electrons, as a result the atom is neutral. Losing or gaining electrons will make the atom electrically charged and we call an electrically charged atom an ion.

Ca 2+ would be the symbol because losing two negative electrons makes calcium's nucleus more positive by two protons.

Answer:

Explanation:

You could look up the shark population near specific coral reefs. You could also go the simple route and say something like, "sharks eat fish so, sharks will go where the fish are and if there are fish in the coral reefs, (which there are) they would be most likely to go there". I know this may not be the answer you were looking for but its the best I've got.
