What is larger a Atom or a Molecule?

Physics

Kipish [7]3 years ago

I believe an Atom is a very powerful source, the basic unit of a chemical element. An atom is a source of nuclear energy.


But a molecule on the other hand isn't so different.
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
I hope that helps, have a fantastic day!

A ray of light traveling through air strikes a piece of diamond at an angle of incidence equal to 56 degrees. Calculate the angu
Montano1993 [528]

Answer:

The angle of separation is  \Delta \theta =  0.93 ^o

Explanation:

From the question we are told that

    The angle of incidence is  \theta  _ i  = 56^o

     The refractive index of violet light  in diamond  is  n_v = 2.46

       The refractive index of red light in diamond is n_r = 2.41

      The wavelength of violet light is  \lambda _v = 400nm = 400*10^{-9}m

         The wavelength of red  light is  \lambda _r = 700nm = 700*10^{-9}m

Snell's  Law can be represented mathematically as

         \frac{sin \theta_i}{sin \theta_r} = n

Where \theta_r is the angle of refraction

=>       sin \theta_r  =   \frac{sin \theta_i}{n}

Now considering violet light

               sin \theta_r__{v}}  =   \frac{sin \theta_i}{n_v}

substituting values

                sin \theta_r__{v}}  =   \frac{sin (56)}{2.46}

                 sin \theta_r__{v}}  =  0.337

                 \theta_r__{v}}  =  sin ^{-1} (0.337)

                 \theta_r__{v}}  =  19.69^o

Now considering red light

               sin \theta_r__{R}}  =   \frac{sin \theta_i}{n_r}

substituting values

                sin \theta_r__{R}}  =   \frac{sin (56)}{2.41}

                 sin \theta_r__{R}}  =  0.344

                 \theta_r__{R}}  =  sin ^{-1} (0.344)

                 \theta_r__{R}}  = 20.12^o

The angle of separation between the red light and the violet light is mathematically evaluated as

                  \Delta \theta = \theta_r__{R}} -  \theta_r__{V}}

substituting values

                  \Delta \theta =20.12 - 19.69

                  \Delta \theta =  0.93 ^o

How did cyanobacteria affect early Earth’s biosphere? Select all that apply. Cyanobacteria allowed organisms that rely on oxygen
FrozenT [24]

Answer:

The correct statements would be

  • Cyanobacteria allowed organisms that rely on oxygen to evolve.
  • Cyanobacteria preceded the first photosynthetic organisms.
  • Cyanobacteria produced excess oxygen.

Cyanobacteria, also termed as blue-green algae are the prokaryotes which are able to perform photosynthesis.

They were the major contributors of oxygen in the atmosphere and thus helped the organisms that rely on oxygen to evolve.

By the process of endosymbiosis, they lead to the origin of plants. The chloroplasts present in green plants is considered as the cyanobacteria living in the plant cell. It helps in photosynthesis and in return plants cell provides shelter to it.

It is believed that the oxygen released from early cyanobacteria reacted with dissolved iron ions to form iron oxide.

Find the voltage
son4ous [18]

Answer:

Explanation:

solve the parallel resistances

30||40     and 50||30

17.14285714   and 18.75

total Resistance = 35.89285714

V = IR

9V = I *35.89285714

9V / 35.89285714 = I

0.250746 = I

Now use the resistance across AB

V = 17.14285714 * 0.250746

V = 4.29850

this is the Voltage drop across AB  :P
