The particular temperature at which vaporisation occurs is known as the boiling point of liquid. Volume of water increases when it boils at 100° C. 1 cm3 of water at 100 ° C becomes 1760 cm3 of steam at 100 ° C.

Calculate the frequencies corresponding to the wavelengths 500.00 nm and 500.10 nm. Use these to check the accuracy of equation

mel-nik [20]

Explanation:

It is given that,

Wavelength, $\lambda_1=500\ nm=5\times 10^{-7}\ m$

Wavelength, $\lambda_2=500.10\ nm=5.001\times 10^{-7}\ m$

We need to find the frequencies from corresponding wavelengths. The frequency of the light is given by :

$f=\dfrac{c}{\lambda}$

c is the speed of light

Frequency 1,

$f_1=\dfrac{c}{\lambda_1}$

$f_1=\dfrac{3\times 10^8\ m/s}{5\times 10^{-7}\ m}$

$f_1=6\times 10^{14}\ Hz$

Frequency 2,

$f_2=\dfrac{c}{\lambda_2}$

$f_1=\dfrac{3\times 10^8\ m/s}{5.001\times 10^{-7}\ m}$

$f_1=5.99\times 10^{14}\ Hz$

Hence, this is the required solution.

If the San Andreas Fault moves 200 cm (2 meters) per big earthquake, and plate movement is xx cm/yr (see question above), how ma

weqwewe [10]

Answer:

Option C

80 years

Explanation:

<em>From Scientific records, the rate of movement of the plate is 0.025 meters</em>

Since the fault moves at the rate of 2 meters per year, to obtain the number of years it will takes to produce an earth quake, we will have to divide the rate of movement of the fault by the rate of movement of the plate.

Number of years for earthquake = $\frac{2}{0.025}$ = 80 years.

Hence, it will take 80 years to produce one big earthquake.
