The temperature of the liquid in a container decreases as the liquid evaporates. Use kinetic theory to explain why.

melisa1 [442]

Answer:

Temperature decreases because the number of collision of the molecules decreases as they escape or evaporate. Molecules are in constant motion. Increase in temperature leads to increase in average kinetic energy of the molecules.

carbon-14 has a half-life of approximately 5,700 years. a fossil shell contain 25% of the original amount of its carbon-14. appr

denis23 [38]

The half-life equation $m=m_{0} (\frac{1}{2})^n$ in which <em>n </em>is equal to the number of half-lives that have passed can be altered to solve for <em>n.</em>

<em> $n = \frac{log(\frac{m}{m_{0}} )}{log(\frac{1}{2})}$ </em>

<em> $\frac{log(\frac{.25}{1} )}{log(\frac{1}{2})} = 2$ </em>

Then, the number of half-lives that passed can be multiplied by the length of a half-life to find the total time.

<em>2 * 5700 = </em>11400 yr

Monochromatic light is incident on a grating that is 75 mm wide and ruled with 50,000 lines. the second-order maximum is seen at

DIA [1.3K]

Answer:

The wavelength of the incident light is $\lambda =$ 400 nm

Explanation:

Given data

Distance between the sits

$d = \frac{0.075}{50000}$

d = 1.5 × $10^{-6}$ m

$\theta = 32.5$ °

m = 2

We know that the wavelength of the incident light is given by

$\lambda = \frac{d\sin \theta}{m}$

Put all the value in above formula we get

$\lambda = \frac{1.5 (\sin 32.5)}{2}$ × $10^{-6}$

$\lambda =$ 4 × $10^{-7}$ m

$\lambda =$ 400 nm

Therefore the wavelength of the incident light is $\lambda =$ 400 nm
