1. Frequency: 
The energy given is the energy per mole of particles:

1 mole contains a number of Avogadro of particles,
, equal to
particles
So, by setting the following proportion, we can calculate the energy of a single photon:

This is the energy of a single photon; now we can calculate its frequency by using the formula:

where
is the Planck's constant
f is the photon frequency
Solving for f, we find

2. Wavelength: 
The wavelength of the photon is given by the equation:

where

is the speed of the photon (the speed of light). Substituting,

Answer:
5 years worth of work (aka all of the homework i currently have)
Answer:
Explanation:
Given
density of cylinder is 
Length of first cylinder is 
radius 
For cylinder 2 
and
are the height above water
E
as object is floating so its weight must be balanced with buoyant force

For 2nd cylinder

Dividing 1 and 2 we get



What is the value of the voltage? There must be one somewhere.
This might be too simple minded, but I'll give it a voltage of 10 Volts.
R = voltage / Current
R = 10 / 0.5
R = 20 volts.
Perhaps you could post a diagram if this is a Kirchhoff Law Question.
Answer: No
Can the change in cyclin concentration during mitosis be explained by the fact that the cell divides in two and thus divides the material in the cell into two smaller volumes?
Explanation: The cyclin concentration is not halved but degraded during mitosis.
There is an increase in cyclin concentrations at interphase. These changes are caused by the presence of Cyclin Dependent Kinase (CDK) complexes. CDK being a substrate of cyclin catalyses cyclin, thereby increasing its concentration. During mitosis, cyclins are destroyed, signifying the end of mitosis and cytokinesis.
Without this process, it will be impossible for the cell to exit mitosis.
