Radiation in the ultraviolet region of the electromagnetic spectrum is quite energetic. It is this radiation that causes dyes to
N76 [4]

The  energy of photon in kJ/mol is 329kJ/mol.

Wavelength of radiation is 370nm. The frequency of given wavelength is

            ν = c / λ

            ν = 3×10^8 / 370×10^-9

            ν = 8.11 × 10^14 s^-1

      Now the energy of photon is:

             E = hν

             E = 6.63×10^-34  J.s/photon × 8.11×10^14s^-1

             E = 5.41× 10^-19  J/photon

         To find in mole

              E = 5.41× 10^-19 × 6.022×10^23

               E = 3.29 ×10^ 5 J/mol

   So, the energy of mole of photon is equal to 329 kJ/mol.

The movement of the planets and other celestial bodies in the Solar System is caused by
Anvisha [2.4K]

The movement of the planets and other celestial bodies in the solar system is actually caused by the sun's gravitational pull or force.

Just like the moon orbits the earth because of the gravitational pull by the earth so does gravitational pull by the sun causes planets' and other celestial bodies' orbit.

A 4 feet tall student went for swimming in a pool.He saw the depth of the water in the pool less than 4 feet.Will he be drowned?
Serjik [45]

Answer:

No, he won't be drowned.

Explanation:

We have given,

The height of the student = 4 feet,

Depth of the pool( in feet ) = x ( say ) < 4 feet,

Since, the depth of the pool < height of the student,

Thus, if the student went for swimming in a pool, however he does not know swimming, he will not be drowned until he is suffering from an injury or external force.
