Answer:

for C-Cl bond $\lambda_1=3.66\times 10^{-9}\ m$

for O-O bond $\lambda_2=2.43\times 10^{-9}\ m$

Explanation:

We have the bond enegy for C-Cl, $BE_1=327\ kJ.mol^{-1}= 327000\times 1.66\times 10^{-22}\ J\ per\ molecule$

bond enegy for C-Cl, $BE_2=494\ kJ.mol^{-1}= 494000\times 1.66\times 10^{-22}\ J\ per\ molecule$

Now as we know the energy of electromagnetic waves is given by:

$E=h.\nu$

here E = BE

Then for C-Cl:

$327000\times 1.66\times 10^{-22}=6.63\times 10^{-34}\times \nu_1$

$\nu_1=8.18733\times 10^{16}\ Hz$

Now wavelength:

$\lambda_1=\frac{c}{\nu_1}$

$\lambda_1=\frac{3\times 10^8}{8.18733\times 10^{16}}$

$\lambda_1=3.66\times 10^{-9}\ m$

For O2:

$494000\times 1.66\times 10^{-22}=6.63\times 10^{-34}\times \nu_2$

$\nu_2=1.236863\times 10^{17}\ Hz$

Now wavelength:

$\lambda_2=\frac{c}{\nu_2}$

$\lambda_2=\frac{3\times 10^8}{1.236863\times 10^{17}}$

$\lambda_2=2.43\times 10^{-9}\ m$

A jogger runs 5.0 km on a straight trail at an angle of 60° south of west. What is the southern component of the run rounded to

mixer [17]

Given :

A jogger runs 5.0 km on a straight trail at an angle of 60° south of west.

To Find :

The southern component of the run rounded to the nearest tenth of a kilometre.

Solution :

We know, southern component is given by :

$d = Dsin \ \theta\\\\d = 5\times sin \ 60^{\circ}\\\\d = -4.33\ km$

Here, negative sign indicates south direction.

Therefore, the southern component of the run rounded to the nearest tenth of a kilometre is 4.3 km.

Hence, this is the required solution.

Kinetic energy into electrical energy

jeyben [28]

A wind turbine is a machine for converting the kinetic energy in wind into electrical energy. Moving air (wind) is used to rotate a machine called a turbine. Inside the wind turbine is an electrical generator. It's the electricalgenerator that transforms the kinetic energy into electrical energy.
