Answer:

hello your question is not properly arranged attached below is the arranged table and solution

answer : attached table below

Explanation:

Given data:

02 molecules size = 10^-10m

smoke particles size = 0.3 mm

cloud droplets size = 20 mm

Rain droplets size = 3 mm

Attached below is a table showing the kind of scattering that is expected to occur at various wave lengths

Note : For Rayleigh scattering the wave particle is smaller than the wave length while for Non-selective scattering the wave particle is greater than the wavelength.

and  For Mie scattering the wavelength is the same as the wavelength.

When a battery, a resistor, a switch, and an inductor form a circuit and the switch is closed, the inductor acts to oppose the c
vladimir1956 [14]

Answer:Time constant gets doubled

Explanation:

Given

L-R circuit is given and suppose R and L is the resistance and inductance of the circuit then current is given by

i=i_0\left [ 1-e^{-\frac{t}{\tau }}\right ]

where i_0 is maximum current

i=current at any time

\tau =\frac{L}{R}=time\ constant

\tau '=\frac{2L}{R}=2\tau

thus if inductance is doubled then time constant also gets doubled or twice to its original value.

Which of these events is caused by contact forces? A. Jupiter's moons staying in orbit B. high tides occurring on the East Coast
elixir [45]

Correct option: D. Earthquakes along the San Andreas fault in California.

The earthquakes occur when the two plates collide with each other. Hence, there is contact between the two plates. So, the contact forces are responsible for the earthquakes.

The force responsible for Jupiter's moons to stay in orbit or the high tides occurring on the east coast is the gravitational force, which is not a contact force as there is no contact between Jupiter and its moon or the earth and the moon which is responsible for the high tides.

Moreover, the magnetic force is a non contact force as it attracts the pins from a distance without any contact between them.

Why does toilet seats stay cold even when the room temperature is warm?​
Andre45 [30]

Answer:

lol While plastic and wood aren't great thermal conductors, they conduct heat faster than air does. Even if the toilet seat is at the same temperature as the air around it, it will feel colder to your but t because heat will move from your skin to the seat at a faster pace Air just doesn't conduct heat very quickly.

A sound wave has a frequency of 620 Hz in air
Studentka2010 [4]

The temperature of the air is -27°C

<u>Explanation:</u>

Given:

Frequency (f)=620 Hz

Wavelength (λ)=0.5 m

To Find:

Temperature of air = ?

Formula to be used:

T=T_{0} \times ( \frac{v^2}{v_{0}^2} -1)

Solution:

velocity\ of\ sound\ at\  0\°C  v_{0}  =327 m/s\\

velocity at the current temperature v=fλ

v=620\times 0.5=310 m/s

Temperature of the air is given by the expression

T=T_{0} \times ( \frac{v^2}{v_{0}^2} -1)\\\\=273\times(\frac{310^2}{327_{0}^2} -1)\\\\=-27 \°C

Thus the temperature of the air is -27°C
