At which dew point temperature would the amount of water vapor in the air be greatest

Physics
1 answer:
Mariana [72]3 years ago
3 0
Dew point indicates the amount of moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. The temperature in which water vapor would be at  20 degrees Celsius or 68 degrees Fahrenheit. The Relative humidity is defined as the ratio of the partial pressure of water vapor to the saturated vapor pressure at a given temperature

Relative Humidity = partial pressure of H₂0/saturated vapor pressure of H₂0  Multiply by 100%

Example at 20⁰C = 17.5 torr

That would mean 120% Humidity

What other objects in our solar systems might influence etiams movement as it travels through space? Why?
GalinKa [24]
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids hope that helps

Calculate the first and second order angles for light of wavelength 400. nm and 700. nm of the grating contains 1.00 x 104 lines
Verdich [7]

Answer:

23.58^{\circ} and 53.13^{\circ}

44.43^{\circ}, second order does not exist

Explanation:

n = Number of lines grating = 1\times10^4\ \text{Lines/cm}

\lambda = Wavelength

m = Order

Distance between slits is given by

d=\dfrac{1}{n}\\\Rightarrow d=\dfrac{1}{1\times 10^4}\\\Rightarrow d=10^{-6}\ \text{m}

\lambda=400\ \text{nm}

m = 1

We have the relation

d\sin\theta=m\lambda\\\Rightarrow \theta=\sin^{-1}\dfrac{m\lambda}{d}\\\Rightarrow \theta=\sin^{-1}\dfrac{1\times 400\times 10^{-9}}{10^{-6}}\\\Rightarrow \theta=23.58^{\circ}

m = 2

\theta=\sin^{-1}\dfrac{2\times 400\times 10^{-9}}{10^{-6}}\\\Rightarrow \theta=53.13^{\circ}

The first and second order angles for light of wavelength 400 nm are 23.58^{\circ} and 53.13^{\circ}.

\lambda=700\ \text{nm}

m = 1

\theta=\sin^{-1}\dfrac{1\times 700\times 10^{-9}}{10^{-6}}\\\Rightarrow \theta=44.43^{\circ}

m = 2

\theta=\sin^{-1}\dfrac{2\times 700\times 10^{-9}}{10^{-6}}

Here \dfrac{2\times 700\times 10^{-9}}{10^{-6}}=1.4>1 so there is no second order angle for this case.

The first order angle for light of wavelength 700 nm are 44.43^{\circ}.

Second order angle does not exist.

An object is moved closer to a lens. Does the focal length of the lens increase, decrease, or stay the same?
shtirl [24]

Answer:

Stay the same

Explanation:

The focal length of a lens is determined by its radius and by the indexes of refraction.  The distance of the object does not affect the focal length.

A 340 g bird flying along at 6.0 m/s sees a 13 g insect heading straight toward it with a speed of 30 m/s. The bird opens its mo
frosja888 [35]

Answer:

V = 4.67 m/s

Explanation:

given,

mass of the flying bird (M)= 340 g = 0.34 Kg

Speed of bird(u₁) = 6 m/s

mass of insect(m) = 13 g = 0.013 Kg

speed of insect(u₂) = 30 m/s

Speed of bird after eating the insect(V) =?

Using conservation of momentum

M u₁ + m u₂ = (M+m)V

V = \dfrac{M u_1+ m u_2}{(M+m)}

V = \dfrac{0.34\times 6 - 0.013 \times 30}{0.34+0.013}

V = \dfrac{1.65}{0.353}

V = 4.67 m/s

the bird's speed immediately after swallowing V = 4.67 m/s
