To solve this problem it is necessary to apply the concepts related to the change of Energy in photons and the conservation of energy.

From the theory we could consider that the energy change is subject to

\Delta E = E_0 -W_f

Where

E_0 =Initial Energy

W_f = Energy loses

Replacing we have that

\Delta E = 1.6-0.8

\Delta E = 0.8eV

Therefore the Kinetic energy of the electron once it has broken free of the metal surface is 0.8eV

Find the equivalent resistance.
frosja888 [35]

Answer:

18 Ω

Explanation:

As K and F are at the same voltage, we can redraw the diagram as in figure 2

Series resistances add directly, so we get figure 3

Adding parallel resistances gets us to figure 4

Now we can move two 6Ω resistances for clarification in figure 5

As the voltage between C and J will be identically split between D and H, there will be no voltage drop across the middle 6Ω resister and no current through it, identical to an infinite resistance, so that 6Ω can be eliminated as in figure 6

Add series resistances to get to figure 7

Add parallel resistances to get to figure 8

Add series resistances to get to figure 9

The chart shows the power ratings of 3 clothes dryers and the time needed to dry a load of 10 towels.
atroni [7]

Answer:

12010

Explanation:

Given:

power    time

4,370     25

4,420     22

4,150      26

To find: difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount

Solution:

Energy = power × time

For clothes dryer x:

energy = 4370 × 25 = 109250

For clothes dryer y:

energy = 4420 × 22 = 97240

For clothes dryer z:

energy = 4150 × 26 = 107900

Dryer x uses the greatest amount of energy and dryer y uses the least amount of energy.

Difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount = 109250 - 97240 = 12010
