Temperature and rate of evaporation are proportional to each other. Surface area: As the surface area increases, the rate of evaporation increases. The surface area and rate of evaporation are proportional to each other. Humidity: The rate of evaporation decreases with an increase in humidity.

Answer:

The three primaryfactors of evaporation are heat, atmospheric pressure (which determines the percentage of moisture) and the movementofair. At the molecular level, there is no strict boundary between the liquid state and the vapor state

An oil layer that is 5.0 cm thick is spread smoothly and evenly over the surface of water on a windless day. A light ray from th

marshall27 [118]

Answer:

The angle of refraction in water 32.12°.

Explanation:

Given that,

Thickness = 5.0 cm

Index of refraction for oil = 1.15

Index of refraction for water = 1.33

Angle = 45°

We need to calculate the angle of refraction

When the ray of light enters from air to oil

Using formula of refraction

$n_{a}\sin\theta_{a}=n_{o}\sin\theta_{o}$

Where, $n_{a}$ = refractive index of air

$n_{0}$ = refractive index of oil

Put the value into the formula

$1\times\sin45=1.15\sin\theta_{o}$

$\sin\theta_{o}=\dfrac{1}{\sqrt{2}\times1.15}$

$\sin\theta_{o}=0.6148$

$\theta_{o}=sin^{-1}0.6149$

$\theta_{o}=37.94^{\circ}$

When the ray of light enters from oil to water

Using formula of refraction

$n_{0}\sin\theta_{0}=n_{w}\sin\theta_{w}$

Where, $n_{w}$ = refractive index of water

$1.15\times\sin37.94^{\circ}=1.33\sin\theta_{w}$

$\sin\theta_{w}=\dfrac{1.15\sin37.94^{\circ}}{1.33}$

$\theta_{w}=\sin^{-1}0.53163$

$\theta_{w}=32.12^{\circ}$

Hence, The angle of refraction in water 32.12°.

A piano tuner strikes a tuning fork at the same time he strikes a piano key with a note of a similar pitch. If he hears 3 beats

DaniilM [7]

The frequency produced by the string could be 437 Hz or it could be 443 Hz.

The frequency of the beats ... 3 Hz ... tells the piano tuner that
the difference between the fork and string frequencies is 3 Hz,
but it doesn't tell her which one is higher or lower.
